From Cristian Condurache + (2017-05-09). + * Kinetis: Disable MPU when not in protected mode. The hardware reset + state of the the MPU precludes any bus masters other then DMA access + to memory. Unfortunately USB and SDHC have there own DMA and will not + have access to memory in the default reset state. This change + disabled the MPU if present on system startup. From David Sidrane + (2017-06-02). + * Kinetis: teensy-3.x Define USBOTG-FS Read from FLASH access in board + config. Allow the board config to define the USBOTG-FS to have Read + access to FLASH. From David Sidrane (2017-06-02). + * Kinetis: usbdev clean up ensuring proper use of HW. Remove magic + numbers from code, documented the use of undocumented bits. Remove + comments and code that were not appropriate for this hardware. + Removed ifdef that's that were always compiled and removed code + blocks that were never compiled. Ensure proper access order to + hardware. Per the reference manual: disable endpoints prior to + configuring buffer descriptor, then enable endpoints Reorganize + interrupt processing order to offload data after processing errors. + Reorganize initialization so that there is a clear initialization + phase, reset phase for both the hardware and software structures. By + breaking the initialization into smaller pieces, the reset interrupt + only resets the resources within the controller that should be reset. + Rework suspend and resume logic so they perform properly. Made attach + and detach functions optional. As they do not make sense for a bus + powered device. Ensured the calls to up_usbinitalize + up_usbuninitalize do not violate the USB spec. From David Sidrane + (2017-06-02). + * WIP: wireless/ieee802154: More work on association/beacon-enabled + networks. From Anthony Merlino (2017-06-02). + * We developed a huge Changeset over a year ago to make USB Composite + configuration dynamical and be able to instanciate the CDCACM + multiple times inside this device. We use this feature to switch + between one in normal and up to three CDCACMs in maintenance boot. + The control path starts in boardctl.c where the configuration for the + device is constructed. There are still a few issues which I'll ask + you to have a look at before this beast can be merged. (1) To be + able to construct the data dynamically I have changed some + USB-Structs to be packed. Maybe there are additional structs to + change (just for completeness – not for current functionality). (2) + I've added the Macro COMPILE_TIME_ASSERTION two times (in + usbmsc_desc.c and in cdcacm_desc.c) to stay private. Maybe you’ll + find a better place. It’s used to check the size of the structs + against the assumptions. (3) I've changed the interface for some + USB-Functions to receive also the dynamic configuration. Maybe this + can be done more elegant. (4) The original NuttX (without the patch) + seems to have problems with a Composite device holding a CDCACM and + an MSC. The USB SET CONFIGURATION request does not to work at all. + This makes the test fail under Windows and under Linux. Applying this + patch doesn’t change anything – because it only changes the + configuration – not the behavior. Maybe you’ll have a look at + this problem before applying the patch. From Frank Benkert + (2017-06-01). + * power: battery_charger: add ioctl for charging input current. From + Juha Niskanen (2017-06-06). + * MTD FLASH drivers: The byte write method of several drivers had a + cloned error: It was not locking the bus while performing byte write + operations (2017-06-06). + * Kinetis:sim ensure isolation of clock dividers for 0 value case. + This fixes a bug were a SoC does not have a clockdivN register and + passes a 0 for the init value. This prevents overflow of the 0 + decremented to -1 (0xffffffff) spilling over to other clockdivN + feilds. From David Sidrane (2017-06-06). + * teensy-3.x:Removed call to khci_usbattach. The call is not need by + the driver if CONFIG_USBDEV_BUSPOWERED=y. The class register will + enable the soft connect pull up. The khci_usbattach call only set a + flag, and that flag is only tested in the class register. On a USB + powered device if we are running we are attached. From David Sidrane + (2017-06-06). + * teensy-3.x:Refreshed config and made board self powered. From David + Sidrane (2017-06-06). + * Kinetis:USB-FS driver. Removed the notion of attached. The + khci_usbattach is call early in the init either in board_initalize or + in board_app_initalize. In either case it is always done prior to the + the class register. Therefore the khci_usbattach call only set a + flag, and that flag is only tested in the class register. The class + register will enable the soft connect pull up. From David Sidrane + (2017-06-06). + * Kinetis:Fixed waning for kinetis_mpudisable. Missing header file + added. From David Sidrane (2017-06-06). + * STM32L4: Ad support for the STM32L475 family. Incomplete -- still + needs pinmap, rcc, otgfs, syscfg (2017-06-08). + * STM32L4: Add L475 syscfg register definitions (2017-06-08). + * STM32L4: Add STM32L475 RCC definitions/logic (2017-06-08). + * STM32L4: Add STM32L475 OTGFS header file. Not fully reviewed + (2017-06-08). + * STM32L4: Add STM32L475 pinmap. Initial cut is just the the L476 + pinmap with unsupported devices removed (2017-06-08). + * configs/stm32f103-minumum SPI: SPIDEV_WIRELESS used when this has + changed to SPIDEV_CONTACTLESS. From Nicolas Estibals (2017-06-08). + * stm32f103-minimum: dd GPIO device driver example for + STM32F103-Minimum. This chang eadds the initialization needed by + stm32f103-minimum board to support the NuttX GPIO Subsystem. From + Alan Carvalho de Assis (2017-06-08). + * STM32L4: Remove some C++ style comments (2017-06-08). + * configs/: a few more places where SPIDEV_WIRELELSS should be + SPIDEV_CONTACTLESS (2017-06-08). + * kinetis: lpserial fixed header inclusion. From David Sidrane + (2017-06-08). + * Kinetis: SPI driver. From David Sidrane (2017-06-08). + * Fix C++ __guard implementation for ARM. The standard C++ ABI that + most platforms follow defines __guard to be 64 bits. The existing + implementation of libxx_cxa_guard.cxx follows this. However, the + 32-bit ARM C++ ABI defines it as 32 bits instead, and changes the + meaning slightly so only the lowest bit is used. This matters because + GCC creates guard symbols without regards to what libxx_cxa_guard.cxx + says. So on ARM, gcc allocates 4 bytes, but __cxa_guard_release + writes 8 bytes, zeroing out another unlucky variable nearby. Fix it + by special-casing 32-bit ARM in libxx_cxa_guard. From Jim Paris + (2017-06-09). + * vfs/poll: fix timeout calculation. From Jim Paris (2017-06-09). + * stm32f103-minimum: Fix a small BUG when reading from output pin. We + need a different read_ops to read from output pin. This patch fixes + the issue. From Alan Carvalho de Assis (2017-06-09). + * testbuild:Added -x to fail build on errors for CI. On CI we want to + know ASAP of a failure. This adds the -x (exit on build failures) + option to faclitate that behavior. Use ${MAKE} ${MAKE_FLAGS} for + make invocation. When -x is provided change MAKE_FLAGS to --silent + --no-print-directory and set -e. Ignore exit status when using grep + for checking for CONFIG_NXWM=y. From David Sidrane (2017-06-10). + * stm32f103-minimum: Use separated read_ops for GPIO interrupt pins. + From Alan Carvalho de Assis (2017-06-11). + * STM32F33: Fix hrtim definitions, Add beginning of HRTIM driver. From + Mateusz Szafoni (2017-06-11). + * STM32 HRTIM: add character driver. From Mateusz Szafoni + (2017-06-11). + * nucleo-f334r8: add HRTIM initialization. From Mateusz Szafoni + (2017-06-11). + * i.MX6: Fix a wrong parameter passed when calling irq_attach() in + imx_serial.c. From Masayuki Ishikawa (2017-06-12). + * Based on the last PR, review all serial driver vector attachment. + Found one additional error and updated all relevant drivers to + current interrupt parameter passing (2017-06-12). + * gethostbyname_r: Fix check for space in buffer (2017-06-12). + * MTD M2PX: If we READ while a write/erase is pending, the command is + ignored and the write/erase continues. If we dont catch this + situation we will return garbage to the user because the flash will + not execute the command. So READ MUST wait for write completion, and + before that, the bus must be locked since it's a precondition to + calling waitwritecomplete(). From Sebastien Lorquet (2017-06-12). + * MTD FLASH driver: Clone Sebastien Lorquet's m25px change to at25, + is25xp, ramtron, and sst25xx (2017-06-12). + * STM32 HRTIM: GPIOs configuration + EEV and FAULT strucutres. From + Mateusz Szafoni (2017-06-12). + * stm32/stm32l4 PWM: While attempting to output a 70 MHz square wave + from the timer output of a STM32 clocked at 140 MHz (which works fine + in baremetal C), I stumbled on what I believe to be an error in + arch/arm/src/stm32/stm32_pwm.c. Line 1304 we are told that: reload = + timclk / info->frequency; which I belive to be incorrect, it should + be: reload = timclk / info->frequency - 1; since starting to count + from 0, if I want to output half of the TIM clock, I must count to 1 + and not to 2. Surely enough, the original code did output 140/3=47 + MHz, while this correction does allow the output up to 70 MHz. I am + not sure this affects most users generating slow PWM (e.g. PX4) but + for frequencies close to the PCLK, indeed the difference becomes + significant. From JM (2017-06-13). + * mtd/w25: add missing locking and fix SPI_SELECT usage for + w25_unprotect. From Jussi Kivilinna (2017-06-13). + * mtd/w25: wait for BUSY flag to clear in w25_readid and w25_unprotect. + W25Q128 datasheet says that all instructions expect 'Read Status + Register' and 'Erase/Program Suspend' are ignored when BUSY flag in + status register is '1'. Therefore wait for busy flag to clear in + w25_readid() and w25_unprotect(). From Jussi Kivilinna + (2017-06-13). + * freedom-k66f: Use SPI driver. Initalize SPI1 on connector J6. No + real use, as of yet. From David Sidrane (2017-06-13). + * pthreads: Move functions from sched/pthreads to libc/pthreads. + These functions just coordinate other OS interface calls but are not + a fundamental OS interfaces and, hence, do not belong within the OS: + pthread_yield(), pthread_once(), pthread_cond_init(), + pthread_cond_destroy(), pthread_barrier_init(), + pthread_barrier_destroy(), and pthread_barrier_wait() (2017-06-14). + * multiple fixes for stm32f1xx RTC clock: (1) compile issues because + of missing RTC_MAGIC #defines, (2) missing functionality based on + RTC_MAGIC in RTC based on stm32_rtcounter.c, (3) IRQ setup from + up_rtc_initialize was later reset in up_irqinitialize, (4) write + access to backup registers without enabling access to backup domain, + (5) possible races in set/cancel alarm. tested with STM32F103C8 + only. device now wakes up from forced STANDBY mode by alarm. From + Leif Jakob (2017-06-14). + * stm32f103-minimum: Fix compiler error in MCP2415 logic (2017-06-14). + * Fixed ARMv7-M Toolchain setting. Cortex-M4 only have Single + Precision FPU. From Hidetaka Takano (2017-06-14). + * wireless/ieee802154: Lots of fixes, cleanup, new functionality. + Functional. From Anthony Merlino (2017-06-14). + * Fixed ARMv7-M Toolchain definition for Cortex-M4. From Hidetaka + Takano (2017-06-15). + * Improve configure.sh behavior: (1) enable to call from top + directory. (2) enable to designate direct path for config. (3) + install .gdbinit if the target has. From Hidetaka Takano + (2017-06-15). + * Update tools/configure.c to same functionality as configure.sh. Add + an array of optional file names. Currently, .gdbinit is the only + optional file but other things like IDE-specific project files might + need to be copied as well (2017-06-15). + * STM32 HRTIM: outputs enable, period and compare functions, cosmetics. + From Mateusz Szafoni (2017-06-15). + * tool/configure will now copy Eclipse project files if they are + present in the board directory file (2017-06-15). + * configs/.gitignore: Make sure that any .gdbinit, .project, or + .cproject files are ignore so that they are less likely to be + included in a patch or PR (2017-06-15). + * wireless/ieee802154: Fixes issue with wrong information being sent in + a rejected association response frame. From Anthony Merlino + (2017-06-15). + * wireless/ieee802154: Fixes issue with wrong information being sent in + a rejected association response frame. From Anthony Merlino + (2017-06-15). + * Rename configs/mrf24j40-radio to mrf24j40-mac (2017-06-15). + * clicker2-stm32: Add a configuratino that will, eventually, be used + for 6loWPAN testing (2017-06-15). + * Fix a typo. And typo in Kconfig file is reflect in all defconfig + files (2017-06-15). + * SAMv7: TWIHS driver add reference counting. From David Sidrane + (2017-06-15). + * STM32 HRTIM: structures for deadtime and chopper, cosmetics. From + Mateusz Szafoni (2017-06-16). + * Clicker2-STM32: Enable RAMLOG in mrf24j40-6lowpan configuration. + Update README (2017-06-16). + * STM32 F4 FLASH: Enable/disable the flash write protection on any + sector. I have verified it to work on the stm32f427. From Sebastien + Lorquet (2017-06-16). + * STM32 SPI/I2S: Back out a bad pin mapping change from + 4ab2a3661ea57211f4ae12fe21c5de3454ba0ef2. Try to staighten out some + I2C3 and SPI3 pin configuration stuff (2017-06-16). + * Clicker2-stm32: Allow both IEEE 802.15.4 MAC character and network + devices to be registered (2017-06-16). + * Clicker2-STM32: Enable networking and 6loWPAN in the + mrf24j40-6lowpan configuration. Fix a couple of new 6loWPAN compile + issues revealed by this new configuration (2017-06-16). + * Merge remote-tracking branch 'origin/master' into ieee802154 + (2017-06-16). + * clicker2-stm32: mrf24j40-6lowpan configuration needs to enabled the + ieee 802.15.4 MAC network device as well (2017-06-16). + * stm32:flash add CONFIG_STM32_STM32F469 to list defining OPTCR1. From + David Sidrane (2017-06-17). + * ieee802.15.4 loopback: Better simulation addressing: sort, extended, + panid, and IP address conversion (2017-06-17). + * ieee802154 MAC: Fix a warning when compiled for a target with 64-bit + addressing (2017-06-17). + * Update some 6loWPAN configurations based on changes to NSH Kconfig + (2017-06-17). + * wireless/ieee802154: Fixes ordering of strings associated with + changed enum. From Anthony Merlino (2017-06-17). + * wireless/ieee802154: Renames mac802154_poll to mac802154_radiopoll to + be more obvious. Merges shared logic for sending data request + commands. Minor improvements and simplified logic. From Anthony + Merlino (2017-06-17). + * STM32 HRTIM: Faults and events configuration, timers mode + configuration, add hrtim ops, ADC triggering and DAC synch events. + From Mateusz Szafoni (2017-06-18). + * Add RFC6775 header file (2017-06-18). + * rfc6775: Fix header, add references, correct naming. This is NOT + ICMPv6, but part of 6LoWPAN that acts like ICMPv6 (2017-06-18). + * wireless/ieee802154: Renames Kconfig option, adds option for + unimplemented receiver priority. From Anthony Merlino (2017-06-18). + * STM32 HRTIM: Fix initialization bug, minor changes. Remove unneeded + definitions. From Mateusz Szafoni (2017-06-18). + * IEEE 802.15.4 MAC: Add list management and prioritization logic that + will permit the MAC layer to support bound multiple clients + (2017-06-18). + * ieee 802.15.4: Need counting protection on the logic that releases + the notification resources. Otherwise, notification handlers may be + operating with a stale pointer (2017-06-18). + * IEEE 802.15.4 Network Driver: Add logic to setup the network mask, + update the MAC-based IPv6 addressing when the network is brought up. + The idea is that addressing changes are supposed to occur only while + the network is down but won't take effect until the network is up + again (2017-06-18). + * Swithches IEEE 802.15.4 based code to using byte arrays instead of + uint16_t values for short address and PAN ID. From Anthony Merlino + (2017-06-19). + * Throw error when error happens in the tcp_listen function. From + Roland Takacs (2017-06-19). + * Support listening sockets in the getsockname() function. From Roland + Takacs (2017-06-19). + * IEEE 802.15.4/6LoWPAN: Correct one more usage of saddr; also update a + README and the TODO list (2017-06-19). + * STM32 ADC: invalidate dma buffer before use. Missing invalidation + caused old samples being fetched from cache. From Jussi Kivilinna + (2017-06-19). + * Enable UDP example in clicker1-stm32/mrf24j40-6lowpan example, make + sure that CONFIG_EXAMPLES_UDP_NETINIT is set in all other + examples/udp configurations (2017-06-19). + * Use struct instead of pointer to the struct as sizeof argument in + memset in usbmsc.c. Otherwise it leads to error: argument to + 'sizeof' in 'memset' call is the same pointer type 'struct + usbmsc_lun_s *' as the destination. From Oleg Evseev (2017-06-19). + * /configs/clicker2-stm32/mrf24j40-6lowpan: Enables both client and + server UDP tests on the target; Update a README file (2017-06-19). + * wireless/ieee802154: Cleans up some endianness issues and fixes poll + request issue. From Anthony Merlino (2017-06-19). + * STM32 L4: Set I2C SDA and SCL pins to open drain mode. From Pekka + Ervasti (2017-06-20). + * STM32 L4: I2C4 was writing to wrong RCC registers. From Juha + Niskanen (2017-06-20). + * STM32 F7: Set I2C4 SDA and SCL pins to open drain mode. From Juha + Niskanen (2017-06-20). + * 6LoWPAN: Add debug statements; Update configuration, need to specific + 6LoWPAN compatible port numbers (2017-06-20). + * mac802154_req_data() can return without releasing the exclsem + (2017-06-20). + * STM32: Allow clock frequencies > 168 Mhz on stm32f427/429. We need + to enable the power overdrive for this case. This patch allows the + required bits to be set in proper sequence. It also modifies the + local register access operations to allow more than 16-bit registers. + From Sebastien Lorquet (2017-06-20). + * Kinetis:I2C driver added I2C3, reference counting and reset. + Refactored the driver to support reference counting and reset added + I2C3. From David Sidrane (2017-06-20). + * ieee802154 network driver now retries if ieee802154_req_data() + returns EINTR. In clicker2-stm32 6LoWPAN configuration, increased + the number of TX descriptors to match then number of IOBs + (2017-06-20). + * Kinetis:I2C fixed mis-placed kinetis_i2c_endwait. Fixed accedently + replaced post with wait. From David Sidrane (2017-06-20). + * ieee802154_req_data: Don't modify the IOB until we are certain that + no EINTR errors will occur. Otherwise, the retry will fail + (2017-06-20). + * ieee802154 MAC: Free allocated TX descriptor if an error occurs after + the descriptor has been allocated (2017-06-20). + * ieee802154: Adds some missing elements to start support for + beacon-enabled networks. From Anthony Merlino (2017-06-20). + * ieee802154: Fixes Kconfig naming for number of TX desc and number of + notifications. From Anthony Merlino (2017-06-21). + * pthread_mutex_unlock(): Missing check for the case where + pthread_mutex_lock() is called when the mutex is not locked. In that + case, it would increment the underlying semaphore avove 1. This is + the fix for a problem noted by initialkjc@yahoo.com (2017-06-21). + * Missing option to select CONFIG_MAC802154_NNOTIF in Kconfig + (2017-06-21). + * clicker2-stm32/mrf24j40-6lowpan: Network now runs on LP work queue + (2017-06-21). + * STM32 L4 DMA: Correct USART3_RX bad channel definition. From Juha + Niskanen (2017-06-21). + * 6LoWPAN: Correct an error in calculating the location of the UDP + header (2017-06-21). + * wireless/ieee802154: Minor naming change to align better with coding + guidelines. From Anthony Merlino (2017-06-21). + * mrf24j40: Fix a warning (which is actually an error) (2017-06-21). + * 6LoWPAN: Correct a few addressing issues. The apps/examples/udp test + now appears to be fully functional. Also reserve two bytes at the + end of the frame for the FCS (2017-06-21). + * Do not search net device when all-zeros address is used. From Roland + Takacs (2017-06-22). + * Fix problems in last commit noted by Jeongchan Kim: last change + returned -EINVAL vs EINVAL; Treat the case where the mutex is already + unlocked just like the case where the mutex is held by another thread + -- return EPERM (2017-06-22). + * Logic of a353602aa9cc50ed958df11af35e3972101b5f40 only applies if + CONFIG_NETDEV_MULTINIC (2017-06-22). + * 6LoWPAN: Fixes needed when extended addressing is enabled. Currently + breaks short addressing. Loopback driver needs to initialize the MAC + meta data; Address decompression logic must have the MAC address to + handle the most common compression cases. Fix a src/dest address + confusion. Fix yet another addressing problem. That does it. + Several recent, proper bugfixes unmasked a few errors in the 6LoWPAN + logic. But I think full functionality is restored (2017-06-22). + * ieee802154: Stubs out some SCAN.request code. From Anthony Merlino + (2017-06-22). + * drivers/net/tun.c: Use critical section instead of semaphore in + tun_ifdown(). From Masayuki Ishikawa (2017-06-23). + * netdb: Fixed buffer size used for sending DNS queries should depend + on the configured DNS name size. From Ritjaina (2017-06-23). + * 6LoWPAN: Add missing IPv6 address creation to HC1 decode logic. Fix a + typo in an index that prevented use with HC1 and extended addresses + (2017-06-23). + * clicker2-stm32/mrg24j40-6lowpan: Add apps/examples/nettest. Refresh + all configurations that enable the nettest (2017-06-23). + * configs/sim/sixlowpan: Disable I2C tool. Not so useful in a + simulation (2017-06-23). + * 6LoWPAN: TCP logic was not obeying MTU packet size limitations. + Other TCP-specific issues also fixed. There remains a major + outstanding issue with ACK handling. Handle case where the local + address is zero (listen socket). Major re-architecting of TCP logic + to properly handle TCP stuf like ACKs and TPC windowing which were + not properly covered in the initial design. Still does not work; + hangs waiting of ACKs.Various fixes for a clean build if either TCP + or UDP are disabled. Given the current state of TCP, it is + recommended that you disable TCP. HC06, copy TCP header as though it + were data. Modify the the way TCP headers are transferred -- yet + again. TCP packet reassembly now seems to work OK, but no there now + does not seem to be a listener on the port (2017-06-24). + * IEEE802.15.4: Update RX statistics in network driver (2017-06-25). + * 6LoWPAN TCP: Fix more ACK handling, fix some callback flag settings. + Now the TCP test appears fully functional on 6LoWPAN (2017-06-25). + * ieee802154: Finishes transmission of beacon frames, and performing a + passive scan. From Anthony Merlino (2017-06-25). + * ieee80215: starts adding support for beacon-enabled networking. From + Anthony Merlino (2017-06-26). + * STM32L4 serial: Allow configuring Rx DMA buffer size. From Juha + Niskanen (2017-06-26). + * stm32f33xxx_rcc: cleanup + move hrtim clock source selection. fix + typo in stm32f33xxx_rcc.h. From Mateusz Szafoni (2017-06-26). + * STM32L4 serial: Allow configuring Rx DMA buffer size. From Juha + Niskanen (2017-06-26). + * 6LoWPAN: Fix duplicate and bad memcpy in loopback driver + (2017-06-26). + * Beacon logic: Damage control. Looks like something went wrong with + the PR merge (2017-06-26). + * ieee802154: Renames mac802154_indalloc to ieee802154_indalloc since + the functions are ieee802154 scoped functions. Improves notification + freeing functionality. Each notification now has a number of + clients. When the last client calls free, the notification is freed + back to the pool. From Anthony Merlino (2017-06-26). + * Clicker2-STM32: Add support for the Telnet client to the + mrf24j40-6lowpan configuration. Useless at the moment because the + NuttX telnet daemon does not yet support IPv6 (2017-06-27). + * ieee802154: Supports get request for coordinator address. From + Anthony Merlino (2017-06-27). + * ieee802154: Finishes beacon association functionality. From Anthony + Merlino (2017-06-27). + * smart: fix wrong freeing of device structure and use-after-free + issues on error paths. From Jussi Kivilinna (2017-06-28). + * net/: IPv6 packet input, Improve checks that the packet is destined + for us. There might be some odd things that can happen in certain + forwarding scenarios (2017-06-28). + * Fix -Werror=implicit-fallthrough on gcc7. From Julien Lecoeur + (2017-06-28). + * Fix warning implicit-fallthrough with arm-none-eabi-gcc 7. From + Julien Lecoeur (2017-06-28). + * 6LoWPAN: Add configurable support for 6LoWPAN star topology. With + this change, the endpoints which are the 'points' of the star will + forward all traffic to the coordinator. The coordinator is assumed + to be the 'hub' of the star. This function also implements IPv6 + forwarding. That forwarding implementation is minimal, just enough + to support the forwarding requirements of the star hub node + (2017-06-28). + * Clicker2-STM32 + net/: Add configurations to support the endpoint + and hub roles in a star topology. Fix various things that broke when + IPv6 forwarding was enabled (2017-06-29). + * 6LowPan: Change how the destination node address is handled in the + start endpoint configuration. When the star endpoint sent the IPv6 + destination address, the HC06 compression logic elided the address -- + meaning that it could be reconstructed by the recipient based on the + receiver's assigned short address. However, when intercepted by the + hub, the uncompressed address does not know the short address of the + recipient and instead uses the short address of the hub. This means + two things: (1) it looks like the hub address is the destination + address, and (2) the uncompressed UDP packet has a bad checksum. + This change assures that the destination IPv6 address is not elided + in the case of the star endpoint configuration (2017-06-30). + * 6LoWPAN: Fix a misconception about HC06 16-bit IPv6 address + compression (2017-06-30). + * 6LoWPAN fix compile issue in star hub configuration (2017-06-30). + * This change backs out the 'misconception' fix of + 76e6dba2e4bfab9515bef2866c5c59fd2a2f0fa0 and reimplements it in a way + that actually seems to work (2017-06-30). + * ieee802154: Random fixes to get beacon-enabled networking more + stable. From Anthony Merlino (2017-06-30). + * 6LoWPAN: TCP send logic was returning a failure in one case when, in + fact, the send was successful (2017-06-01). + * include/nuttx/net and net/: Move private prototype of + netdev_foreach() from the public include/nuttx/net/net.h to the + private net/netdev/ndetdev.h header file where it belongs + (2017-07-01). + * ieee802154: Cleans up some wireless logging.

Add some fragments of TCP + forwarding logic (2017-07-03). + * IPv6 forwarding logic must decrement the TTL and drop the packet if + the hop limit is exceeded (2017-07-04). + * IP forwarding. Adds a little more structure to handle passing + packets received on one network device to another network device. + Logic is still incomplete (2017-07-04). + * UDP networking: The TTL (time to live) was not being set in the IPv4 + or IPv6 header unless the UDP socket was bound (2017-07-04). + * SAME70-Xplained: Add MRF24J40 support (2017-07-04). + * I've found that the interrupts aren't enabled since nothing updates + them after btn_poll() marks the file descriptor structure as being + polling.

Last of the conversions of defconfig files to + compressed format (2017-07-09). + * ieee802154: Improves internal timer logic to handle work serially. + Before, the MAC timer used a watchdog to schedule work with the high + priority worker queue. However, since everything in the MAC is + supposed to be serialized through the use of the high priority work + queue, but the timer uses a watchdog, there are some unintended + consequences. To simplify, we now use the delayed work feature of the + work queue. From Anthony Merlino (2017-07-09). + * Update configure.sh, configure.bat, configure.c: With compressed + format, part of the installation requires that we run 'make + olddefconfig' to restore the uncompressed defconfig format. Also, + while I was at it, I also added options to select host platform on + configure command line (2017-07-10). + * tools/refresh.sh: Now runs make savedefconfig before copying the new + defconfig file in place; Also, added a new option --defaults. Since + the number of defaults that you now have to answer is so large, the + option lets you just accept the default values. So it works just + like --slilent but still prompts you for the decision to save or + discard the new defconfig file (2017-07-10). + * tools/tesbuild.sh: Fix missing $ before variable name (2017-07-10). + * configs/clicker2-stm32: Adds support for per-function-call stack + checking.

From Jeff + (2017-07-28). + * We discovered a problem with the samv7 mcan driver which results, + under some circumstances, in a very high CPU load. The problem + occurs, and is easily reproducible, if the device is connected to a + CAN network with a wrongly configured CAN speed (baud rate). In our + tests we set the CAN speed of the device to 1000000 and the speed of + the other CAN nodes to 500000. The device is restarted and sends a + CANopen "bootup message" to the CAN network. This results in huge + amount of errors messages on the CAN bus, probably because of the CAN + feature for acknowledging error messages. The error messages can’t + be read by the device because of the misconfigured CAN speed, instead + the CAN chip reports lots of errors, which are reported to the + application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled). + The CAN errors are reported from the CAN chip via interrupts and thus + the interrupt load is very high in this scenario. To fix the problem + the driver now disables each RX error interrupt after it is occurred. + The RX error interrupts are turned back on if at least one CAN + message is received successfully. From Stefan Kolb (2017-07-28). + * tcdrain implementation based on a new term ioctl. From Sebastien + Lorquet (2017-07-28). + * Spirit Network Driver: Create build directories, Add radio + initialization, interrupt handling logic, packet transmissin and + reception logic.

From Titus von Boxberg (2017-07-28). + * STM32 F7: No board specific dithering values used; corrected + dithering init. Corrected LIPOS/LIPCR calculation. Change only + polarity bits in LTDC_GCR. From Titus von Boxberg (2017-07-29). + * STM32_RCC_DCKCFGR2 has nothing to do with PLLI2S; PLLI2S is not + dependent on LTDC, instead on SAICLK1/2 generated from PLLI2S. From + Titus von Boxberg (2017-07-29). + * To use an external oscillator module (not just a crystal) with the + STM32F4, one needs to enable the HSEBYP bit in the RCC_CR register. + This change allows an integrator to define STM32_RCC_CR_HSEBYP in + their board.h file if they want this configuration. From Jeff + (2017-07-30). + * 6LoWPAN PktRadio: Some initial changes to support raw packet radios + without IEEE 802.15.4 with 6LoWPAN. Add missing MetaData-related + prototypes and initialization logic. Perform a major renaming to + make room in the 6LoWPAN name space for packet radios. Replace + metadata input parameter type from struct ieee802154_data_ind_s to + void*. This permits radios with different MAC metadata to interact + with 6LoWPAN. Includes many changes to handle variable length radio + addresses. No longer just short and exteneded; any length.Remove + explicit type struct ieee802154_frame_meta_s from derive interface + methods. Replace with a opaque void * type so that other radio meta + data structures may use the interfaces. Add a new radion interface + to get properties of the radio.

From Masayuki + Ishikawa (2017-08-07). + * Spirit bugfixes: Was hanging occasionally because there was no + mechanism to restart the poll timer if poll was not performed because + Spirit ws busy. Fixed by not checking if Spirit is busy. The TX + poll can be performed asynchronouly while spirit is busy; any + outgoing data will queued until Spirit is ready. Fixed handling of a + timeout condition. Failure to transmition to the TX state would fail + (timeout) if in a race condition Spirit already committed to the RX + state. The driver needs to recover the state properly and avoid + debug assertions in this event (2017-08-07). + * STM32 USB: I'm working on bringing up USB full-speed support on + STM32F405.  My board does not include a USB power switch, VBus + sensing, over current detection, or ID pin. This commit add a + config STM32_OTGFS_VBUS_ CONTROL which lets us selectively disable + VBus sensing and control.  I also sneaked in a change to disable the + configgpio call for the ID pin, which is only used in OTG mode which + isn't supported yet.  The only pins that need to be initialized + should be OTGFS_DP and OTGFS_DM. These changes let a USB mouse + enumerate on my platform if it's plugged in on power-up.  Plugging, + unplugging, clicking, or moving the mouse cause NSH to stop + responding.  Because I'm using the ramlog, I don't have useful debug + messaging yet, so there's a lot more work I have to do to + troubleshoot it or get my JTAG debugging set up, but these patches + shouldn't hurt anything.  I'm hoping my issue is something simple I + overlooked in configuration. From Jeff (2017-08-07). + * I discovered while working on the SAMV7 mcan driver that the + implementation of the CAN error handling is suboptimal. In the + current implementation the many errors are implemented as pending + errors. But those errors are not pending, the errors occurred and + are gone directly afterwards. This commit changes the described + behavior and simplifies the handling of CAN errors. From Stefan Kolb + (2017-08-07). + * IPv6: Remove comparisons to the address with all ones set. IPv6 + does not support broadcast addresses and certainly not in that form. + Replace with multicast addresses beginning with 0xff02 (2017-08-07). + * ICMPv6: Support source link-layer address option in RA.

Regardless of the stat of + CONFIG_LIBC_WCHAR the non mb/wc definitions such as mbstate_t, + wint_t, wctype_t need to be exported. From David Sidrane + (2017-08-10). + * inet_ntop: Was printing negative values for fields >127 + (2017-08-11). + * procfs: Add support for routing tables at proc/net/route + (2017-08-11). + * Unify GCC/Clang config.

Updated + comment to proper refernce manual for STM32F7 not STM32F4. Added + stm32_dmacapable input paramaters documentation. From David Sidrane + (2017-08-17). + * STM32 F7: DMA add dcache alignment check in stm32_dmacapable. In the + case dcache write-buffed mode is used (not write-through) buffer + alignment is required for DMA transfers because a) + arch_invalidate_dcache could lose buffered writes data and b) + arch_flush_dcache could corrupt adjacent memory if the maddr and the + mend+1, the next next address are not on ARMV7M_DCACHE_LINESIZE + boundaries. From David Sidrane (2017-08-17). + * STM32 F7: SDMMC remove widebus limitation on DMA. There is no + documantation for the STM32F7 that limits DMA on 1 bit vrs 4 bit + mode.

Add configs/sim configuration for testing + (2017-08-19). + * STM32 COMP: add default INM configuration and some missing + COMP1,3,5,7 code. From Mateusz Szafoni (2017-08-20). + * 6LoWPAN/PF_IEEE802154: Created radiodev.h and renamed various + structures to provide a better separation between 6LoWPAN networking + and PF_IEEE802154 address family (2017-08-20). + * STM32 DAC: fix some configuration logic.

More fixes to device registration + and to IEEE 802.15.4 loopback driver for PF_IEEE802154 without + 6LoWPAN. Changes to conditional compilation so that PF_IEEE802154 + can build without 6LoWPAN (2017-08-20). + * drivers/net/tun.c: Currently cannot support TAP mode unless Ethenet + is enabled (2017-08-20). + * PktRadio loopback driver: Fix compile problem by removing + inappropriate const storage class (2017-08-20). + * Networking: Remove driver based backlog support. This affects the + entire network, but is used by only one driver. The only supported + RX backlog is now via common read-ahead buffering (2017-08-21). + * PF_IEEE802154 socket family: (1) Improve some backlog counting + logic; add more assertions to catch cases where the backlog count + might deviate from the actual backlog. (2) Add a maximum backlog + option. This will prevent overrun of the RX frame queue if many + frames are received from the radio, but no application is receiving + the queued data. (3) On input, there may be a list of frames + provided, not just one. When closed() and connection is freed, also + need to free any frames remaining in the RX queue (2017-08-21). + * Network procfs: Add support for network procfs statistics when + nothing is enabled but PF_IEEE802154 (2017-08-21). + * STM32 DAC: Add support for HRTIM triggering.

From Juha Niskanen + (2017-08-22). + * drivers/lcd: ssd1306: (1) Separate lcd_dev_s setup to separate + object. g_oleddev takes 1 KiB because framebuffer and was allocated + to .data section because of lcd_dev_s function pointer setup. Move + lcd_dev_s setup out, so that g_oleddev goes to .bss and avoid wasting + ROM. (2) Fix memory corruption caused by ssd1306_getrun(). + ssd1306_getrun was writing one extra byte (with value 0) past target + buffer when pixlen is multiple of 8. When pixlen was not multiple of + 8, last byte of buffer was fully cleared, instead of modifying only + the (pixlen % 8) bits of last byte. (3) Add support for board power + control. ThingseeOne has regulator for controlling display power + on/off. Patch adds support for board based power control to SSD1306 + driver.

TODO: Untested. + Does not have poll() support. From Juha Niskanen (2017-08-25). + * 6LoWPAN: The original, Contiki-based design used only a single + buffer for reassemblying larger packets. This could be a problem + issue for hub configurations which really need the capability + concurrently reassemble multiple incoming streams concurrently. + These was also a design issue in that the reassembly buffer could be + corrupted by outgoing packets. The design was extended to support + multiple reassembly buffers, each associated with the reassembly tag + and source address. This assures that there can be be no corruption + of the reassembly once it has started (2017-08-26). + * Simulator: Adds necessary functionality to build Simulator under ARM + Linux.

"AN 4667 - + STM32F7 Series system architecture and performance" recommends to + disable read-modify-write on DTCM: "If the DTCM-RAM is used as data + location and the variables used are byte or/and halfword types, since + there is no ECC management in this RAM on the STM32F7 Series, it is + recommended to disable the read-modify-write of the DTCM-RAM in the + DTCM interface (inthe DTCMCR register) to increase the performance." + From Jussi Kivilinna (2017-09-01). + * Networking: IGMP: Remove special support for interrupt level + processing (there is none) and fix some timer cancellation logic. In + many files, correct comments. There is no interrupt level processing + in the networking layer (2017-09-02). + * stm32_dac.c: fix compilation when DMA disabled for channel. From + Mateusz Szafoni (2017-09-02). + * Extend the RTC framework with an alarm read ioctl (RTC_RD_ALARM). + Through it consumer could get configuration settings about previously + scheduled hardware alarms (active status, hours, minutes, seconds). + From Boris Astardzhiev (2017-09-03). + * STM32 F7: Port Boris Astardzhiev's RTC change for STM32L4 to STM32F7 + (2017-09-03). + * STM32: Port Boris Astardzhiev's RTC change for STM32L4 to STM32 + (2017-09-03). + * Kinetis: Unverified implementation of the alarm read function. + Pretty simple because the Kinetis RTC is just a 1Hz counter + (2017-09-03). + * STM32 HRTIM: add burst mode configuration, rename some definitions. + From Mateusz Szafoni (2017-09-03). + * Update net_timedwait() and net_lockedwait() call sites to handle + negated errno in return value. From Jussi Kivilinna (2017-09-04). + * stm32f7: Add new configuration option for enabling flash ART + Accelerator and flash prefetcher. From Jussi Kivilinna + (2017-09-04). + * Simulation: Fix building 32-bit simulation on 32-bit X86. From + Jussi Kivilinna (2017-09-04). + * waitpid(): Corrects two problems when + CONFIG_SCHED_HAVE_PARENT+CONFIG_SCHED_CHILD_STATUS are enabled: (1) + Was erroring out if the waited for task had already exited, and (2) + was not freeing resources when a wait was completed.
