<p><b>nuttx-6.6 Release Notes</b>:
|
||||
<p>
|

The 72<sup>nd</sup> release of NuttX, Version 6.5, was made on June 21, 2011 and is available for download from the
|
||||
The 73<sup>5d</sup> release of NuttX, Version 6.6, was made on July 11, 2011 and is available for download from the
|
||||
<a href="http://sourceforge.net/projects/nuttx/files/">SourceForge</a> website.
|
||||
Note that release consists of two tarballs: <code>nuttx-6.6.tar.gz</code> and <code>apps-6.5.tar.gz</code>.
|
||||
Both may be needed (see the top-level <code>nuttx/README.txt</code> file for build information)
|
||||
The change log associated with the release is available <a href="#currentrelease">here</a>.
|
||||
Unreleased changes after this release are available in SVN.
|
||||
These unreleased changes are also listed <a href="#pendingchanges">here</a>.
|
||||
</p>
|
||||
<p>
|
||||
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).
|
||||
</p>
|
||||
<p>
|
||||
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
|
||||
</p>
|
||||
<ul>
|
||||
<li>
|
||||
<p><b>SoC Robotics Amber Web Server (ATMega128)</b>.
|
||||
This port of NuttX to the Amber Web Server from
|
||||
<a href="http://www.soc-robotics.com/index.htm">SoC Robotics</a>.
|
||||
The Amber Web Server is based on an Atmel ATMega128 (128Kb FLASH but
|
||||
only 4Kb of SRAM).
|
||||
</p>
|
||||
<p><b>STATUS</b>:
|
||||
Work on this port has stalled due to toolchain issues.
|
||||
It is complete, but untested.
|
||||
</p>
|
||||
<li>
|
||||
<p><b>Micropendous 3 (AT9USB647)</b>.
|
||||
This port of NuttX to the <a href="http://code.google.com/p/opendous/">Opendous</a>
|
||||
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.
|
||||
</p>
|
||||
<p>
|
||||
<p><b>STATUS</b>:
|
||||
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).
|
||||
</p>
|
||||
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.
|
||||
</li>
|
||||
<li>
|
||||
<p><b>PJRC Teensy++ 2.0 (AT90USB1286)</b>.
|
||||
This is a port of NuttX to the PJRC Teensy++ 2.0 board.
|
||||
This board was developed by <a href="http://pjrc.com/teensy/">PJRC</a>.
|
||||
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.
|
||||
</p>
|
||||
<p><b>STATUS</b>:
|
||||
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
|
||||
<a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
|
||||
</p>
|
||||
<p><b>Unfinished Stuff</b>.
|
||||
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.
|
||||
</p>
|
||||
Corrections to the USB host mass storage class driver
|
||||
</li>
|
||||
<li>
|
||||
STM32 bugfixes: serial driver, GPIO interrupt handling
|
||||
</li>
|
||||
<li>
|
||||
LPC17xx: Changes for a success compilation with no console.
|
||||
</li>
|
||||
<li>
|
||||
Corrections to the Teensy AT90USB SD driver
|
||||
</li>
|
||||
<li>
|
||||
Changes for a clean compilation under the ZDS-II toolchain.
|
||||
</li>
|
||||
</ul>
|
||||
|
||||
<p><b>AVR-Specific Issues</b>.
|
||||
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.
|
||||
</p>
|
||||
<p>
|
||||
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:
|
||||
</p>
|
||||
<ol>
|
||||
<ul>
|
||||
<li>
|
||||
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 <code>printf</code> strings from FLASH
|
||||
(but there are still <code>printf</code> issues for that target)
|
||||
</li>
|
||||
<li>
|
||||
Create a special version of printf that knows how to access strings that reside in FLASH (or EEPROM).
|
||||
Added a configuration for the <a href="http://www.sureelectronics.net">Sure Electronics</a> PIC32MX board.
|
||||
However, higher priority tasks have stopped work on that configuration.
|
||||
</li>
|
||||
</ol>
|
||||
<li>
|
||||
Added several new configurations for the <a href=" http://www.st.com/">STMicro</a> STM3210E-EVAL board.
|
||||
</li>
|
||||
<li>
|
||||
Added support for the STM3210E-EVAL board: (1) LCD in either landscape or portrait mode, and (2) interrupting buttons.
|
||||
</li>
|
||||
<li>
|
||||
Added a configuration option to use different serial ports for debug and for the NSH serial console
|
||||
(there are some issues with CR-LF expansion and character echo if NSH is not run on the console).
|
||||
</li>
|
||||
<li>
|
||||
Standardized the button press and button interrupt interfaces so that they are common across all boards.
|
||||
</li>
|
||||
<li>
|
||||
Added a new graphics example that focuses on placing text on the background while pop-up windows occur.
|
||||
Text should continue to update normally with or without the popup windows present.
|
||||
</li>
|
||||
<li>
|
||||
Added ARM stack checking logic.

* arch/arm/src/stm32/stm32_gpio.c: GPIO interrupt handling for pin
|
||||
numbers were being aliased: 5-9 together and 10-15 together. Extended
|

the logic to peform decoding of GPIO interrupts and unique dispatching
|
||||
for all 16 pins.
|
||||
* configs/stm3210e-eval/nxtext: Add a configuration for the apps/examples/nxtext
|
||||
example. This example focuses on placing text on the background while
|
||||
pop-up windows occur. Text should continue to update normally with or without
|
||||
the popup windows present.

nuttx-6.6
|

^^^^^^^^^
|
||||
|
||||
The 73rd release of NuttX, Version 6.6, was made on July 11, 2011 and is
|
||||
available for download from the SourceForge website. The 6.6 release
|
||||
adds several smaller featurs but is mostly a bugfix release.
|
||||
|
||||
Bugfixes include
|
||||
|
||||
* 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.
|
||||
* Corrections to the USB host mass storage class driver
|
||||
* STM32 bugfixes: serial driver, GPIO interrupt handling
|
||||
* LPC17xx: Changes for a success compilation with no console.
|
||||
* Corrections to the Teensy AT90USB SD driver
|
||||
* Changes for a clean compilation under the ZDS-II toolchain.
|
||||
|
||||
Minor features:
|
||||
|
||||
* Add logic to extract printf strings from FLASH (but there are still printf
|
||||
issues for that target)
|
||||
* Added a configuration for the Sure Electronics PIC32MX board. However,
|
||||
higher priority tasks have stopped work on that configuration.
|
||||
* Added several new configurations for the STMicro STM3210E-EVAL board.
|
||||
* Added support for the STM3210E-EVAL board: (1) LCD in either landscape or
|
||||
portrait mode, and (2) interrupting buttons.
|
||||
* Added a configuration option to use different serial ports for debug
|
||||
and for the NSH serial console (there are some issues with CR-LF
|
||||
expansion and character echo if NSH is not run on the console).
|
||||
* Standardized the button press and button interrupt interfaces so that they
|
||||
are common across all boards.
|
||||
* Added a new graphics example that focuses on placing text on the background
|
||||
while pop-up windows occur. Text should continue to update normally with
|
||||
or without the popup windows present.
|
||||
* Added ARM stack checking logic.
|
||||
|
||||
