NuttX-6.10
----------

The 77th release of NuttX, Version 6.10, was made on October 6, 2011
and is available for download from the SourceForge website. Note
that release consists of two tarballs: nuttx-6.10.tar.gz and
apps-6.10.tar.gz. Both may be needed (see the top-level nuttx/README.txt
file for build information).

This release corresponds with SVN release number: r4028

This release includes a few new features and several important bug fixes.
The new features (some still incomplete) include:

* CDC ACM serial class device-side driver

* RTC: Now supports hi-res and lo-res hardware RTC. The lo-res RTC
runs at 1Hz.

* STM32 I2C driver. Now supports faster, polled mode of operation.
Added an I2C trace capability.

* ADS7843E touchscreen driver. As used on the SAM3U-EK development
board.

* AT91SAM3U SPI driver. To support the ADS7843E toucscreen

* X11 Support on simulation target. Build errors in the X11 windows
for the simulated target have been correct. Added support for a
simulated touchscreen on the X11 window (based on mouse inputs).

* System Timer. Added support for a 64-bit system timer.

* TIFF Support. Added a TIFF library (currently used for storing
LCD screen shots).

* LCD Support. Added a test to verify that we read and write correct
to LCD GRAM memory.

* I2C tool. Extended to support to include a verify command and
repetitions and auto-address increment for most commands.

* USB terminal example. Line oriented serial bridge connects a host
USB serial terminal to a host UART serial terminal.

* Build System. apps/ Makefile will now include external directories
in the application build.

Bugfixes, order roughly on decreasing criticality include:

* Message Queues. Correct errors in mq_timedsend() and
mq_timedreceive().

* FAT. Writes that cross sector boundaries, stray write into the FAT,
and a FAT long file name issue

* NXFFS. Added a missed error check. Files cannot be opened for
writing if they are already opened for reading.

* Library: fopen() for append modse was not appending.

* STM32 I2C driver. Correct another conflict between concurrent FSMC
and I2C1 accesses. Fixed some bad error detection logic.

* STM32 SDHC driver. Interrupts were being left disabled.
