    - This release includes two partially completed ports, several new features, and a - couple of important bug fixes. The two partially completed ports are: -

      -
    • The STMicro STR71x processor and configuration for the Olimex STR-P711 board, and
      • -
    • The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board.

    + This release includes the following new feature:

    - Progress on these ports is stalled (as detailed in the ChangeLog). -

    -

    - The new features focus primarily on management of block devices and extensions of - the NuttShell (NSH). These new features include: -

      -
    • A loop device that converts a file into a block device,
      • -
    • A block to character (BCH) driver that allow access a block device as if it were character device,
      • -
    • Added strcasecmp() and strncasecmp() libc functions, and
      • -
    • Added the 'dd' and 'losetup' commands to NSH. These commands (along with mkfatfs and mount), - give good managment of filesystems on the target.
      • -
    -

    +
      +
    • Add poll() and select() APIs that may be used to monitor for data + availability on character devices or TCP/IP sockets. +
      • +
    • Implemented support TCP/IP connection backlog. + This allows poll()/select() to wake-up on new connections to a listener socket. +
      • +
    • 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). +
      • +
    • 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. +
    • Added support for fixed precision math. +
      • +
    • Added support for outgoing multicast packets. +
      • +

    Several bugs were fixed, the most important of which are: -

      -
    • Fixd a race condition workaround delay in LPC214X SPI logic. This was also - the cause of some bad MMC/SD performance on that platform.
      • -
    • Fixed a recently introduced FAT file system problem: It would mount a (invalid) - FAT file system even if the medium is not formatted!
      • -
    • 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.
      • -

    +
  • 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. +
    • +
  • 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 fgetc() work much more smoothly. +

    • - The FAT filesystem has had many bugs fixed in it and, I think, is now maturing - and becoming stable. -

-	* 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.

+	* 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.

+	  waiting for connections, with a subsequent call to accept() to use the backlogged connection.
