NuttX-7.2
|
|
---------
|
|
|
|
The 102nd release of NuttX, Version 7.2, was made on April 29, 2014,
|
|
and is available for download from the SourceForge website. Note
|
|
that release consists of two tarballs: nuttx-7.2.tar.gz and
|
|
apps-7.2.tar.gz. Both may be needed (see the top-level nuttx/README.txt
|
|
file for build information).
|
|
|
|
Additional new features and extended functionality:
|
|
|
|
* Core OS:
|
|
|
|
- Add support for CLOCK_REALTIME. From Macs N.
|
|
|
|
* Network Utilities:
|
|
|
|
- Add a very primitive NTP client.
|
|
- DNS resolver: Long needed major clean up for coding style and
|
|
unification of naming conventions (resolv vs dns).
|
|
|
|
* Common Drivers:
|
|
|
|
- Add a new MTD driver that can be used to contain another driver and
|
|
force its apparent sector size to be 512 bytes.
|
|
- If DCD can support queuing of stall requests, then the USB MSC stall
|
|
work around delays are not necessary.
|
|
- Redesign threading module used with the USB MSC driver. It was using
|
|
pthreads before and these were changed to a kernel thread. The reason
|
|
for this has to do with task grouping: A pthread is a memory of the
|
|
group of the task that started it. A kernel thread is independent of
|
|
the task that started in (other than knowing it as the parent). This
|
|
allows me to remove so kludge logic to "deparent" the pthread on
|
|
startup.
|
|
- Update the MIO183QT-9A LCD driver to support reading from the LCD.
|
|
From Toby Duckworth.
|
|
- Timer "upper half" driver and l"lower half" interface definition from
|
|
Bob Doiron.
|
|
|
|
* Atmel SAM4E/4S Board Support:
|
|
|
|
- All SAM4E configurations updated to run with 120MHz CPU speed and
|
|
with the CMCC enabled.
|
|
- Support for the SAM4S Xplained Pro board from Bob Doiron.
|
|
- Add watchdog driver. From Bob Doiron.
|
|
|
|
* Atmel SAM4E/4S Drivers:
|
|
|
|
- Add a USB full speed device driver (UDP) for the SAM4E.
|
|
- Add support in HSMCI and SPI drivers to invalidate cached memory if
|
|
the CMCC is enabled.
|
|
- Add logic to handle SPI word widths > 8
|
|
- Port RTC driver from SAMA5 to SAM3/4. From Bob Doiron.
|
|
- HSMCI: Extensions from Bob Doiron needed to support PDC-based HSMCI
|
|
DMA transfers. Verified on the SAM4S Xplained Pro.
|
|
|
|
* Atmel SAMA5:
|
|
|
|
- Add support for the SAMA5D36 chip.
|
|
- Add functions to calculate PLLACK, PCK, and MCK frequencies given
|
|
the main clock frequency.
|
|
- Implemented RAM functions. When booting directly into NOR flash,
|
|
reconfiguring the PLL while executing out of NOR FLASH causes
|
|
crashes. This was fixed by David Sidrane by implementing RAM
|
|
functions. The killer code is copied and executed from ISRAM and
|
|
the crash is avoided.
|
|
|
|
* Atmel SAMA5 Drivers:
|
|
|
|
- Add support for the SAMA5D3 DBGU.
|
|
|
|
* Atmel SAMA5 Board Support:
|
|
|
|
- Add a board support configuration for the Atmel SAMA5D3 Xplained
|
|
board running out of SDRAM. When booting from SDRAM, start-up logic
|
|
needd to query the PMC registers to determine the MCK, PCK, etc.
|
|
- For all SAMA5 boards, added support for 528MHz clocking.
|
|
|
|
* TI Tiva/Stellaris:
|
|
|
|
- Modify the logic to disables the interrupts and sets the default
|
|
interrupt priority so that it uses the ICTR to get the number of
|
|
interrupt lines/registers. This is instead of using some fixed
|
|
number of initializations based a priori knowledge of the number
|
|
of interrupt lines in the MCU.
|
|
|
|
* STMicro STM32
|
|
|
|
- Add support for the STM401RE. From Frank Bennett.
|
|
|
|
* STMicro STM32 Boards:
|
|
|
|
- STM32F4Discovery: Add support to register keyboard and mouse
|
|
classes if so configured. From Leo.
|
|
- Add support for the Nucleo-F401RE board. From Frank Bennett.
|
|
|
|
* STMicro STM32 Drivers:
|
|
|
|
- Add STM32 Ethernet IGMP hashing support. From Manuel Stühn.
|
|
- OTG FS Host: USB host tracing added by Leo.
|
|
|
|
* Freescale Kinetis
|
|
|
|
- Modify the logic to disables the interrupts and sets the default
|
|
interrupt priority so that it uses the ICTR to get the number of
|
|
interrupt lines/registers. This is instead of using some fixed
|
|
number of initializations based a priori knowledge of the number
|
|
of interrupt lines in the MCU.
|
|
|
|
* NXP LPC17xx
|
|
|
|
- Modify the logic to disables the interrupts and sets the default
|
|
interrupt priority so that it uses the ICTR to get the number of
|
|
interrupt lines/registers. This is instead of using some fixed
|
|
number of initializations based a priori knowledge of the number
|
|
of interrupt lines in the MCU.
|
|
|
|
* ZiLOG ZNEO Drivers
|
|
|
|
- Added ZNEO ESPI driver.
|
|
|
|
* Library:
|
|
|
|
- Finish incomplete support for ferror(). From Macs N.
|
|
|
|
* Documentation:
|
|
|
|
- UsbTrace.html: Add some discussion of the USB monitor.
|
|
|
|
* Configuration/Build System:
|
|
|
|
- compiler.h: Add macro UNUSED() that can be used to eliminate
|
|
warnings about variables that are set to values that are not
|
|
used.
|
|
|
|
* Debugging Support:
|
|
|
|
- Add a configuration option to enable dumping of the USB trace buffer
|
|
on assertion.
|
|
|
|
* Applications:
|
|
|
|
- IGMP Example: Fill out Kconfig file; update makefile so that the
|
|
IGMP example can be used as an NSH built-in application. From Manuel
|
|
Stühn.
|
|
- lcdrw Example: Fill out empty Kconfig file.
|
|
- touchscreen Example: Add a configuration option to indicate if
|
|
architecture-specific initialized is required, yes or no.
|
|
- System usbmsc: Back out the USBMSC daemon... it is no longer needed
|
|
with the recent fix to the USBMSC class driver.
|
|
- NSH: malloc/free IOBUFFER for 'cat' and 'hexdump' commands instead of
|
|
using the stack. From Bob Doiron.
|
|
- cpuhog, serialblaster, and serialrx Examples: Stress test examples
|
|
added by Bob Doiron.
|
|
|
|
Bugfixes (see the ChangeLog for details). Some of these are very important:
|
|
|
|
* Core OS:
|
|
|
|
- errno_get_errno_ptr() and getpid(): Add some checks. If these
|
|
functions are called very early in initialization before the tasking
|
|
structures are initialized, they would not behave properly.
|
|
|
|
* Networking:
|
|
|
|
- IGMP-related bug fixes from Manuel Stühn.
|
|
- In netdev_findbyaddr(), skip network devices that are in the "down"
|
|
state. It does not make sense to consider an address match with a
|
|
"down" device. From Brennan Ashton.
|
|
|
|
* Network Utilities:
|
|
|
|
- DHCPD: The correct value of the PAD option. Should be zero, not
|
|
one. From Brennan Ashton.
|
|
- Corrections to the NTP client from Manuel Stuehn.
|
|
|
|
* Common Drivers:
|
|
|
|
- usbhost.h: Fix some USB HID-related conditional compilation. From Leo.
|
|
- USB HID mouse driver: Don't include NAKs from the device in the error
|
|
count. From Leo.
|
|
|
|
* TI Tiva/Stellaris:
|
|
|
|
- Add corrected control logic for TM4C125GXL based on logic from Daniel
|
|
Carvalho with modifications. The LM4F120 also works well with this
|
|
change.
|
|
|
|
* STMicro STM32 Drivers:
|
|
|
|
- STM32 F2 SPI: Correct a mapping for SPI MOSI pin. From dlsitzer.
|
|
- OTG FS Host: Fixes related to low-speed devices and interrupt
|
|
endpoints from Leo. Necessary in order to use a USB HID mouse
|
|
device.
|
|
- STM32 SDIO: The dmaflight method must be conditioned on
|
|
CONFIG_SDIO_PREFLIGHT. Noted by Pelle Windestam.
|
|
- Sourceforge Ticket #26. up_prioritize_irq should not be called
|
|
if CONFIG_ARCH_IRQPRIO is not defined.
|
|
|
|
* Atmel SAM3/4:
|
|
|
|
- Fix some backward conditional compilation in the start-up logic.
|
|
- Fix initialization of the default interrupt priorities. This is
|
|
a critical bug fix!
|
|
- SAM4S: Fix error in macros that disable peripheral clocking. From
|
|
Bob Doiron.
|
|
|
|
* Atmel SAMA5:
|
|
|
|
- Fix double mapping of SDRAM when executing out of SDRAM. In this
|
|
case, the SDRAM was already mapping in arm_head.S.
|
|
- In clock configuration, the BMS bit handling was fixed to match
|
|
what the HW really does. From David Sidrane.
|
|
- TLB Bufferable bit did not do what I thought it was going to do.
|
|
I though I was selecting a write-through cache, but the result was
|
|
that all caching was disabled and NOR FLASH accesses were very slow.
|
|
- Move the un-definitions of __ramfuncs__ from the clock configuration
|
|
.c file to the .h file. Otherwise, the attribute will be applied
|
|
differently for the prototype and the function definition.
|
|
Sourceforge patch 38 from Luciano Neri.
|
|
|
|
* Atmel SAMA5 Drivers:
|
|
|
|
- Fix a case in the UDPHS driver where received status was not being
|
|
cleared, causing OUT SETUP commands to fail.
|
|
- TWI data sending fails to increment the number of bytes transferred
|
|
on first byte sent. from David Sidrane.
|
|
- If running from SDRAM, then BOARD_MCK_FREQUENCY is not a constant
|
|
and cannot be used in conditional compilation. All drivers fixed
|
|
EXCEPT for the PWM and Timer/Counter drivers which will need some
|
|
more extensive redesign.
|
|
|
|
* Atmel SAMA5 Boards:
|
|
|
|
- SAMA5D3x-EK: The red LED is controlled by PE24 which is also the
|
|
camera/ISI interface reset line. So if the a camera is installed,
|
|
then we must avoid controlling the red LED or we inadvertently
|
|
also reset the camera module. Noted by David Sidrane.
|
|
- Header files reference type xcpt_t in certain configurations and
|
|
so must include nuttx/irq.h. This is Sourceforge bug 25 submitted
|
|
by Luciano Neri.
|
|
|
|
* NXP LPC17xx Drivers
|
|
|
|
- arm/src/lpc17xx/Kconfig and lpc17_ethernet.c: The default interrupt
|
|
priority should be default, not the highest priority (2014-4-19).
|
|
|
|
* ZiLOG ZNEO
|
|
|
|
- Fix calculation of timer reload and prescaler. The timer frequency
|
|
was way too fast.
|
|
|
|
* Library:
|
|
|
|
- strncpy(): Change ordering of test and copy. Logic would have
|
|
failed if n=0; one byte was always copying before testing
|
|
for the end of the copy.
|
|
- Fix a counting error in the return value from sscanf(). Noted by
|
|
kfrolov. Also, sscanf() should return EOF if no values were
|
|
converted.
|
|
- Fix a logic error in ftell(). It was simply using the file offset
|
|
and did not take into account data buffered in memory. From Macs N.
|
|
- sccanf(): Use stroul() vs strol() with %u format otherwise, range
|
|
of values is restricted because of sign bit. From kfrolov.
|
|
|
|
* Configuration/Build System:
|
|
|
|
- Fix a build error that occurs when only USB device tracing is enabled.
|
|
|
|
* NuttShell (NSH):
|
|
|
|
- Fix NuttShell version number display in the NSH welcome message.
|
|
version.h was not being included.
|
|
|
|
* Other Applications:
|
|
|
|
- sysinfo: CONFIG_VERSION_BUILD is a string an needs to be
|
|
printed with %s, not %d. Noted by Librae.
|
|
- nxplayer: Compilation failure in one configuration reported by
|
|
Manuel Stuhn.
|
|
- System sdcard: Remove an STM32 dependency. From Bob Doiron.
|
|
- telnetd Example: Naming is confused. In someplaces 'telnetd',
|
|
and in others 'shell.' All changes to telnetd. Noted by Pelle
|
|
Windestam.
