ZDS-II Compiler Versions
^^^^^^^^^^^^^^^^^^^^^^^^
The ZDS-II version 4.10.2 will not compiler NuttX. It reports "internal
errors" on some of the files. Upgreads to ZDS-II are available for download
from the Zilog website: http://www.zilog.com/software/zds2.asp
4.10.2
The ZDS-II version 4.10.2 will not compile NuttX. It reports "internal
errors" on some of the files. Upgrades to ZDS-II are available for
download from the Zilog website: http://www.zilog.com/software/zds2.asp
Thusfar, I have encountered no insolvable problems with the newer 4.11.0
version of the toolchain.
4.11.0
NuttX compiles correctly with the newer 4.11.0 version of the ZDS-II
toolchain. However, I have found a few issues:
- The code will not run without the -reduceopt option. There is,
apparently, some optimization related issue. This issue has not
been analyzed as of this writing.
- Not all NuttX logic will not run with the -regvars option. There is
at least one failure that has been reported to ZiLOG as incident 81400.
- The Pascal add-on interpreter includes a large switch statement and
exposes another compiler problem. This is reported as incident 81459.
If you use any version of ZDS-II other than 4.11.0 or if you install ZDS-II
at anly location other than the default location, you will have to modify
at any location other than the default location, you will have to modify
two files: (1) configs/z16f2800100zcog/*/setenv.sh and (2)
configs/z16f2800100zcog/*/Make.defs.
