|
||||
This 47<sup>th</sup> release of NuttX was made on December 21, 2009 and is available for download from the
|
||||
<a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a> website.
|
||||
The change log associated with the release is available <a href="#currentrelease">here</a>.
|
||||
Unreleased changes after this release are available in CVS.
|
||||
These unreleased changes are listed <a href="#pendingchanges">here</a>.
|
||||
</p>
|
||||
<p>
|
||||
The release extends the support for the STMicro STM32 microcontroller.
|
||||
Minimal support for the STM3210E-EVAL development board based around the STM32F103ZET6
|
||||
MCU was released in NuttX-0.4.12 and extended in Nuttx-0.4.13 to include initial USB support.
|
||||
This completes the STM32F103ZET6 support and adds:
|
||||
The previous NuttX release was 4.14.
|
||||
The major revision number has been incremented to indicate that an
|
||||
incompatibility with previous nuttx releases has been introduced.
|
||||
This version adopts standard fixed width integer names as specified by the
|
||||
ANSII C99 standard.
|
||||
The core logic of NuttX is older than that standard and did not conform to it.
|
||||
</p>
|
||||
<p>
|
||||
New Generic RTOS Features:
|
||||
If you have applications running on nuttx-4.14, those applications should continue
|
||||
to build and execute without problem on nuttx-5.0.
|
||||
However, if you have device drivers or other OS-internal logic, you will probably
|
||||
have to make some minor changes to your code to use this version.
|
||||
Below is a summary of those changes:
|
||||
<ul>
|
||||
<li>Added generic support that can be included in any block driver to provide
|
||||
read-ahead buffering and write buffering for improved driver performance.</li>
|
||||
<li>Added a generic worker thread that can used to defer processing from an
|
||||
interrupt to a task.</li>
|
||||
<li>Defined a generic SD/SDIO interface can can be bound to a MMC/SD or SDIO
|
||||
driver to orovide SDIO support.</li>
|
||||
<li>Implemented a an SDIO-based MMC/SD driver using this new SDIO interface</li>
|
||||
<li>If you include <code>sys/types.h</code> to get the non-standard, fixed width
|
||||
integer types (<code>uint32</code>, <code>uint16</code>, <code>ubyte</code>, etc.),
|
||||
that is no longer necessary.
|
||||
<li>Instead, you will need to include <code>stdint.h</code> where the new fixed width
|
||||
integer types are defined (<code>uint32_t</code>, <code>uint16_t</code>, <code>uint8_t</code>, etc.).
|
||||
<li>You will have to change all occurrences of the following types:
|
||||
<ul><pre>
|
||||
uint32 -> uint32_t
|
||||
uint16 -> uint16_t
|
||||
ubyte -> uint8_t
|
||||
uint8 -> uint8_t
|
||||
sint32 -> int32_t
|
||||
sint16 -> int16_t
|
||||
sint8 -> int8_t
|
||||
</pre></ul>
|
||||
<li>In addition, the non-standard type <code>boolean</code> must replaced with the
|
||||
standard type <code>bool</code>.
|
||||
The type definition for <code>bool</code> is in <code>stdbool.h</code>.
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
New STM32-specific Features:
|
||||
This change in typing caused small changes to many, many files.
|
||||
The changes was verified that all configurations in the release still build correctly
|
||||
(other than the SDCC-based configurations).
|
||||
Regression testing was performed on a few configurations, but it is possible that minor build
|
||||
issues still exist (if you encounter any, please let me know and I will
|
||||
help you to fix them).
|
||||
</p>
|
||||
<p>
|
||||
In the course of the regression testing, several important bugs unrelated
|
||||
to the type changes were found and corrected.
|
||||
Two of these are critical bugs:
|
||||
<ul>
|
||||
<li>Add support to configure an STM32 input GPIO to generate an EXTI interrupt.</li>
|
||||
<li>Added support for buttons on the STM3210E-EVAL board.</li>
|
||||
<li>Implemented an STM32 version of the common the SDIO interface.</li>
|
||||
<li>Added a configuration to exercise the STM32 with the USB mass storage
|
||||
device class example.</li>
|
||||
<li>Fixed an important error in the RX FIFO handling logic of the LM3S6918
|
||||
Ethernet driver.
|
||||
<li>Corrected the handling of TCP sequence numbers in the TCP stack.
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
This release also corrects some important bugs in the earlier STM32 releases:
|
||||
<ul>
|
||||
<li>Correct error handling in the mount() logic.</li>
|
||||
<li> Fixed several STM32 DMA-related issues. Integrated and debugged STM32 DMA
|
||||
functionality that was added in 0.4.12.</li>
|
||||
<li>Fixed several bugs in the STM32 USB device-side driver.</li>
|
||||
</ul>
|
||||
And other less important bug fixes as detailed in the <a href="#currentrelease">ChangeLog</a>.
|
||||
</p>
|
||||
<p>
|
||||
NOTE: This version, 4.14, is equivalent to what would have been called 0.4.14
|
||||
to follow 0.4.13. The zero has been eliminated from the front of the version
|
||||
number to avoid confusion about the state of development: Some have interpreted
|
||||
the leading zero to mean that the code is in some way unstable. That was not
|
||||
the intent. Beginning in January 2010, I will switch to the 2010.nn versioning
|
||||
as many others have done to avoid such confusion.
|
||||
The primary focus of this release was standards compatibility, but a few new
|
||||
features were added including a (1) Flash Translation Layer (FTL) that will
|
||||
support filesystems on a FLASH device and (2) partial ports for the STM32F107VC
|
||||
and HCS12 M9S12NE64 MCUs. Those ports are very incomplete as of this writing.

nuttx-5.0
|
||||
^^^^^^^^^
|
||||
|
||||
This is 47th release of NuttX and the successor to nuttx-4.14. This
|
||||
major revision number has been incremented to indicate that an
|
||||
incompatibility with previous nuttx releases has been introduced. This
|
||||
version adopts standard fixed width integer names as specified by the
|
||||
ANSII C99 standard. The core logic of NuttX is older than that
|
||||
standard and did not conform to it.
|
||||
|
||||
If you have applications running on nuttx-4.14, those applications
|
||||
should continue to build and execute without problem on nuttx-5.0.
|
||||
However, if you have device drivers or other OS-internal logic, you
|
||||
will probably have to make some minor changes to your code to use
|
||||
this version. Below is a summary of those changes:
|
||||
|
||||
o If you include sys/types.h to get the non-standard, fixed width
|
||||
integer types (uint32, uint16, ubyte, etc.), that is no longer
|
||||
necessary.
|
||||
o Instead, you will need to include stdint.h where the new fixed width
|
||||
integer types are defined (uint32_t, uint16_t, uint8_t, etc.).
|
||||
o You will have to change all occurrences of the following types:
|
||||
|
||||
uint32 -> uint32_t
|
||||
uint16 -> uint16_t
|
||||
ubyte -> uint8_t
|
||||
uint8 -> uint8_t
|
||||
sint32 -> int32_t
|
||||
sint16 -> int16_t
|
||||
sint8 -> int8_t
|
||||
|
||||
o In addition, the non-standard type 'boolean' must replaced with the
|
||||
standard type 'bool'. The type definition for 'bool' is in stdbool.h
|
||||
|
||||
This change in typing caused small changes to many, many files. It was
|
||||
verified that all configurations in the release still build correctly
|
||||
(other than the SDCC-based configurations). Regression testing was
|
||||
performed on a few configurations, but it is possible that minor build
|
||||
issues still exist (if you encounter any, please let me know and I will
|
||||
help you to fix them).
|
||||
|
||||
In the course of the regression testing, several important bugs unrelated
|
||||
to the type changes were found and corrected.
|
||||
|
||||
o Fixed an important error in the RX FIFO handling logic of the LM3S6918
|
||||
Ethernet driver.
|
||||
o Corrected the handling of TCP sequence numbers in the TCP stack.
|
||||
o And other less important bugs as detailed in the ChangeLog.
|
||||
|
||||
The primary focus of this release was standards compatibility, but a
|
||||
few new features were added including a (1) Flash Translation Layer (FTL)
|
||||
that will support filesystems on a FLASH device and (2) partial ports
|
||||
for the STM32F107VC and HCS12 C9S12NE64 MCUs. Those ports are very
|
||||
incomplete as of this writing.
