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>
|
||||
</ul>
|
||||
</p>
|
||||
<ul>
|
||||
<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>
|
||||
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>
|
||||

|
||||
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

nuttx-0.3.18 2008-11-16 Gregory Nutt <spudmonkey@racsa.co.cr>
|
||||
* 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 <spudmonkey@racsa.co.cr>
|
||||
* 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
