This release includes two partially completed ports, several new features, and a
couple of important bug fixes. The two partially completed ports are:
<ul>
<li>The STMicro STR71x processor and configuration for the Olimex STR-P711 board, and</li>
<li>The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board.</li>
</ul>
</p>
This release includes the following new feature:
<p>
Progress on these ports is stalled (as detailed in the ChangeLog).
</p>
<p>
The new features focus primarily on management of block devices and extensions of
the NuttShell (NSH). These new features include:
<ul>
<li>A loop device that converts a file into a block device,</li>
<li>A block to character (BCH) driver that allow access a block device as if it were character device, </li>
<li>Added strcasecmp() and strncasecmp() libc functions, and </li>
<li>Added the 'dd' and 'losetup' commands to NSH. These commands (along with mkfatfs and mount),
give good managment of filesystems on the target.</li>
<li>Add <code>poll()</code> and <code>select()</code> APIs that may be used to monitor for data
availability on character devices or TCP/IP sockets.
</li>
<li>Implemented support TCP/IP connection backlog.
This allows <code>poll()</code>/<code>select()</code> to wake-up on new connections to a listener socket.
</li>
<li>Added definition of a framebuffer driver and implement framebuffer drivers for the
simulated platform and the TI DM320 (untested as of the inital check-in).
</li>
<li>Partially developed a graphics framework based on the framebuffer drivers, however,
this will not be ready for use for a few more release.
Currently this includes only a few color conversion routines and some rasteizing functions.
A tiny windowing system is under development but not ready for check-in yet.
<li>Added support for fixed precision math.
</li>
<li>Added support for outgoing multicast packets.
</li>
</ul>
</p>
<p>
Several bugs were fixed, the most important of which are:
<ul>
<li>Fixd a race condition workaround delay in LPC214X SPI logic. This was also
the cause of some bad MMC/SD performance on that platform.</li>
<li>Fixed a recently introduced FAT file system problem: It would mount a (invalid)
FAT file system even if the medium is not formatted!</li>
<li>Corrected two iother important errors in the FAT lseek implementation:
(1) the sectors-per-cluster value was being reset to "1" and (2) important
lseek logic was omitted when the seek position was zero.</li>
</ul>
</p>
<li>Fixed an important bug in the TCP/IP buffering logic.
When TCP/IP read-ahead is enabled and not recv() is in-place when a TCP/IP packet is received,
the packet is placed into a read-ahead buffer.
However, the old contents of the read-ahead buffer were not being cleared and old data would
contaminate the newly received buffer.
</li>
<li>Changed the behavior of the serial driver read.
It now returns data as it is available rather than waiting for the full requested read size.
This makes functions like <code>fgetc()</code> work much more smoothly.
</li>
<p>
The FAT filesystem has had many bugs fixed in it and, I think, is now maturing
and becoming stable.
</p>
<p>
These changes were verified only on the mcu123.com NXP LPC2148 board, the Hitachi
SH1_LCEVB1 board, and the Linux simulator, all using a Linux development environment.
These changes were verified only on the Neuros OSD (ARM) and the Linux simulator using a
Linux development environment.

* Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711
board (STR71x testing is stalled because I have been unable to get OpenOCD to
communicate with my JTAG wiggler on Linux).
* Fix race condition workaround delay in LPC214X SPI logic. This was also the cause of the
very bad MMC/SD performance.
* Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board
* Re-built all configurations that use SDCC and Zilog toolchains to make sure they still
build (they didn't, but they do now).
* Fixed several erroneous "list empty" checks in the CAN driver.
* Hitachi SH-1 passes (reduced) examples/ostest; the examples/nsh test still fails.
There are remaining instabilities that make the port un-usable. The nature of these is
not understood; the behavior is that certain SH-1 instructions stop working as advertised.
This could be a silicon problem, some pipeline issue that is not handled properly by the
gcc 3.4.5 toolchain (which has very limit SH-1 support to begin with), or perhaps with the
CMON debugger. At any rate, I have exhausted all of the energy that I am willing to put
into this cool old processor for the time being.
* Renamed configuration item CONFIG_PROC_STACK_SIZE as CONFIG_IDLETHREAD_STACKSIZE: It now
only controls the size of the stack for the IDLE thread. Added CONFIG_USERMAIN_STACKSIZE:
This is the size of stack used with the user_start() thread is created. The two stacks
no longer have to be the same.
* Add a loop device that converts a file into a block device.
* Each NSH command can not be disabled through a configuration setting. All of these
settings make the configuration of NSH potentially complex but also allow it to squeeze
into very small memory footprints.
* Added a block to character (BCH) driver. This is kind of the reverse of the loop
device; it allows you access a block device like a character device.
* NSH: Added the 'dd' command
* NSH: Added the 'losetup' command
* Fixed a FAT bug: After recent changes, it would mount a (invalid) FAT file system
even if the medium is not formatted!
* Corrected two important errors in FAT lseek implementation: (1) the sectors-per-cluster
value was being reset to '1' and (2) important lseek logic was omitted when the seek
position was zero.
* Fixed a bug in getopt(). It would fail if on certain combinations of terminal argument
types.
nuttx-0.3.19 2008-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* Add poll() and select() APIs (in the initial check-in, these work only with character devices)
* Add poll() methods to /dev/null, /dev/zero, pipes, fifos, and serial drivers.
* Add examples/poll for testing poll() and select()
* Fix hostile behavior of getc, fgetc, getchar, etc.: the serial driver was waiting for a
full buffer of read data before return. This means that getc would stall when it needed
to refill the input buffer. The old behavior (read full blocks) might be useful in other
contexts, so it is still available within the driver as a configuration option.
* Implement poll() and select() support for TCP/IP sockets
* Fixed an important bug in the TCP/IP buffering logic. When TCP/IP read-ahead is enabled
and not recv() is in-place when a TCP/IP packet is received, the packet is placed into
a read-ahead buffer. However, the old contents of the read-ahead buffer were not being
cleared and old data would contaminate the newly received buffer.
* Implemented support for connection backlog. The size of the backlog is specified by the
second argument of the standard listen() API. Hooks are provided to support poll()/select()
waiting for connections, with a subsequent call to accept() to use the backlogged connection.
* Fixed a minor bug in accept(). It should allow the address and addresslen values to be NULL
* Added first-cut definition for a framebuffer interface (and simulated framebuffer for testing
purposes only)
* Added fixed precision math support
* Added some color converson routines into what may become a real graphics library someday.
* Added a framebuffer driver for the DM320 (untested on initial check-in)
* Network: add support for outgoing multicast addresses
* Added some rasterizers to the graphics library
