This release contains on a few -changes. The primary purpose of this release is to synchronize with -the release of the pascal-0.1.0 add-on package. +This is the 19th release of NuttX. This release includes the +preliminary port of NuttX to the ZiLOG z16f 16-bit microcontroller. +This port was verified using the ZiLOG z16f2800100zcog Development +and the ZiLOG ZDS-II toolchain. See http://www.zilog.com for +further information. -This release of NuttX includes the following changes: +I emphasize that this is a preliminary release of the z16f port and +is only alpha or, perhaps, pre-alpha quality as of this writing. +There are a list of known issues in the TODO file in the root of +the NuttX directory. The overall quality of NuttX (excluding the +z16f port) continues to improve beyond the late beta level. -* Fixes for use with SDCC compiler -* Added a simulated z80 target (arch/z80) -* Fix deadlock errors when using stdio but with no buffering -* Add support for the add-on Pascal P-Code interpreter (pcode/) - (see the pascal-0.1.0 package) +The z16f port required numerous changes to NuttX to handle: -This release were verified only on the simulated Z80 and and host -simulation targets. As usual, any feedback about bugs or suggestions -for improvement would be greatly appreciated. +* NEAR and FAR addressing, and +* Use of a Windows native toolchain in a Cygwin build environment. -This tarball contains a complete CVS snapshot from January 6, 2007. +In addition to the z16f port, at least one very critical bug was +found and corrected in NuttX: The thread-specific errno value of one +task was being randomly trashed when a different thread exitted. -NOTE: There was an error in the initial 0.3.6 release that prevented -a successful build unless the Pascal add-on was present. The -tarball was patched to include the fix. Make sure that you download -the nuttx-0.3.6.1.tar.gz version to avoid this problem. +This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD +(ARM9), and the simulation platforms. As usual, any feedback about bugs +or suggestions for improvement would be greatly appreciated. + +This tarball contains a complete CVS snapshot from January 31, 2008. |
