ZDS-II Compiler Versions
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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
|
|
|
|
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 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.
|
|
|
|
Configuration Subdirectories
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- source/ and include/
|
|
These directories contain common logic for all z16f2800100zcog
|
|
configurations.
|
|
|
|
Variations on the basic z8f162800100zcog configuration are maintained
|
|
in subdirectories. To configure any specific configuration, do the
|
|
following steps:
|
|
|
|
cd <nuttx-top-directory>/tools
|
|
./configure.sh z16f2800100zcog/<sub-directory>
|
|
cd <nuttx-top-directgory>
|
|
make
|
|
|
|
Where <sub-directory> is the specific board configuration that you
|
|
wish to build. The following board-specific configurations are
|
|
available:
|
|
|
|
- ostest
|
|
This builds the examples/ostest application for execution from FLASH.
|
|
See examples/README.txt for information about ostest.
|
|
|
|
- pashello
|
|
|
|
Configures to use examples/pashello for execution from FLASH
|
|
See examples/README.txt for information about pashello.
|
|
|
|
Check out any README.txt files in these <sub-directory>s.
