| NuttX-0.3.7 |
| ----------- |
| |
| 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. |
| |
| 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. |
| |
| The z16f port required numerous changes to NuttX to handle: |
| |
| * NEAR and FAR addressing, and |
| * Use of a Windows native toolchain in a Cygwin build environment. |
| |
| 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 exited. |
| |
| 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. |
