nuttx-6.6 Release Notes:

- The 72nd release of NuttX, Version 6.5, was made on June 21, 2011 and is available for download from the + The 735d release of NuttX, Version 6.6, was made on July 11, 2011 and is available for download from the SourceForge website. + Note that release consists of two tarballs: nuttx-6.6.tar.gz and apps-6.5.tar.gz. + Both may be needed (see the top-level nuttx/README.txt file for build information) The change log associated with the release is available here. Unreleased changes after this release are available in SVN. These unreleased changes are also listed here.

- The 6.5 release is all about support for the Atmel 8-bit AVR family. - I have been interested in the AVR family for some time but because of the - severe SRAM constraints and because of the availability of many tiny schedulers - for the AVR, it has not been "on the radar screen." - However, I have recently become interested because of interest expressed by - members of the Nuttx forum and because of the availability of newer, larger - capacity AVR parts (that I don't have yet). -

-

- This release includes support for the following AVR boards. - As with any initial support for new architectures, there are some incomplete areas and a few caveats that need to be stated. - Here they are, ordered from the least to the most complete: + The 6.6 release adds several smaller featurs but is mostly a bugfix release. + Bugfixes include

  • -

    SoC Robotics Amber Web Server (ATMega128). - This port of NuttX to the Amber Web Server from - SoC Robotics. - The Amber Web Server is based on an Atmel ATMega128 (128Kb FLASH but - only 4Kb of SRAM). -

    -

    STATUS: - Work on this port has stalled due to toolchain issues. - It is complete, but untested. -

    -
  • -

    Micropendous 3 (AT9USB647). - This port of NuttX to the Opendous - Micropendous 3 board. - Micropendous3 may be populated with an AT90USB646, 647, 1286, or 1287. - I have only the AT90USB647 version for testing. - This version has very limited memory resources: 64Kb of FLASH and 4Kb of SRAM. -

    -

    -

    STATUS: - The basic port was released in NuttX-6.5. - This basic port consists only of a "Hello, World!!&qquo; example - that demonstrates initialization of the OS, creation of a simple task, - and serial console output. - The tiny SRAM limits what you can do with the AT90USB647 (see issues below). -

    + Fixed several NX Graphics bugs: Rendering fonts at >8 bits-per-pixel, + graphics move logic, and display artifacts that appear when a window is closed.
  • -

    PJRC Teensy++ 2.0 (AT90USB1286). - This is a port of NuttX to the PJRC Teensy++ 2.0 board. - This board was developed by PJRC. - The Teensy++ 2.0 is based on an Atmel AT90USB1286 MCU with 128Kb of FLASH and 8Kb of SRAM; - a little more room to move than the AT90USB647. -

    -

    STATUS: - The basic port was released in NuttX-6.5. - This basic port consists of a "Hello, World!!" example and - also slightly simplified NuttShell (NSH) configuration (see the - NSH User Guide). -

    -

    Unfinished Stuff. - An SPI driver and a USB device driver exist for the AT90USB as well as a USB mass storage configuration. - However, this configuration is not fully debugged as of the NuttX-6.5 release. -

AVR-Specific Issues. - The basic AVR port is solid and biggest issue for using AVR is its tiny SRAM memory and its Harvard architecture. - Because of the Harvard architecture, constant data that resides to flash is inaccessible using "normal" memory reads and writes (only SRAM data can be accessed "normally"). - Special AVR instructions are available for accessing data in FLASH, but these have not been integrated into the normal, general purpose OS. -

- Most NuttX test applications are console-oriented with lots of strings used for printf and debug output. - These strings are all stored in SRAM now due to these data accessing issues and even the smallest console-oriented applications can quickly fill a 4-8Kb memory. - So, in order for the AVR port to be useful, one of two things would need to be done: + Minor features include:

-
    +
    • - Don't use console applications that required lots of strings. - The basic AVR port is solid and your typical deeply embedded application should work fine. - Or, + Add logic to extract AVR printf strings from FLASH + (but there are still printf issues for that target)
    • - Create a special version of printf that knows how to access strings that reside in FLASH (or EEPROM). + Added a configuration for the Sure Electronics PIC32MX board. + However, higher priority tasks have stopped work on that configuration.
