NuttX-5.15
|
||
|
|
----------
|
||
|
|
|
||
|
|
The 62nd release of NuttX, NuttX-5.15, was made on December 12,
|
||
|
|
2010. This release includes several bugfixes as well as feature
|
||
|
|
enhancements, primarily for the Olimex LPC1766-STK board.
|
||
|
|
|
||
|
|
Important bugfixes included:
|
||
|
|
|
||
|
|
* Additional fixes needed with the TCP sequence number problem
|
||
|
|
"fixed" in NuttX-5.14.
|
||
|
|
* In the send() logic, now checks if the destination IP address
|
||
|
|
is in the ARP table before sending the packet; an ARP request
|
||
|
|
will go out instead. This improves behavior, for example, on
|
||
|
|
the first on the first GET request from a browser
|
||
|
|
* All USB class drivers need to call DEV_CONNECT() when they are
|
||
|
|
ready to be enumerated. That is, (1) initially when bound to
|
||
|
|
the USB driver, and (2) after a USB reset.
|
||
|
|
* The SPI_SETBITS macro was calling the SPI setmode method.
|
||
|
|
* And several other bug fixes of lower importance (see the
|
||
|
|
ChangeLog for details).
|
||
|
|
|
||
|
|
And feature enhancements:
|
||
|
|
|
||
|
|
* The LPC176x Ethernet driver was using all of AHB SRAM Bank0 for
|
||
|
|
Ethernet packet buffers (16K). An option was added to limit
|
||
|
|
the amount of SRAM used for packet buffering and to re-use any
|
||
|
|
extra Bank0 memory for heap.
|
||
|
|
|
||
|
|
* Enabled networking and SD/MMC card support in the Olimex
|
||
|
|
LPC1766-STK NuttShell (NSH) configuration.
|
||
|
|
|
||
|
|
* The LPC176x USB driver is now fully fully functional.
|
||
|
|
* Added an optional cmddata() method to the SPI interface. Some
|
||
|
|
devices require an additional out-of-band bit to specify if the
|
||
|
|
next word sent to the device is a command or data. The cmddata
|
||
|
|
method provides selection of command or data.
|
||
|
|
|
||
|
|
* A driver for the Nokia 6100 LCD (with either the Phillips PCF8833
|
||
|
|
LCD controller and for the Epson S1D15G10 LCD controller) and
|
||
|
|
an NX graphics configuration for the Olimex LPC1766-STK have
|
||
|
|
been added. However, neither the LCD driver nor the NX
|
||
|
|
configuration have been verified as of the this release.
