ZDS-II Compiler Versions
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Version 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
|
|
|
|
Version 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.
|
|
|
|
Version 4.11.1
|
|
|
|
As of this writing (30 September 2010), the latest release of ZDS-II for the
|
|
ZNEO is 4.11.1. It is unknown if this release includes fixes for incidents
|
|
81400 and 81459 or not. It is unknown if the code will run without -reduceopt
|
|
either. (Basically, it compiles with 4.11.1, but is untested with that version).
|
|
|
|
Version 5.0.1
|
|
|
|
On November 29, 2012, all of the z16f configurations were converted to use 5.0.1,
|
|
but have not been verified on a running target.
|
|
|
|
Paths were also updated that are specific to a 32-bit toolchain running on
|
|
a 64 bit windows platform. Change to a different toolchain, you will need
|
|
to modify the versioning in Make.defs and setenv.sh; if you want to build
|
|
on a different platform, you will need to change the path in the ZDS binaries
|
|
in those same files.
|
|
|
|
Other Versions
|
|
|
|
If you use any version of ZDS-II other than 5.0.1 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. Simply edit these two files, changing
|
|
5.0.1 to whatever.
|
|

|
Issues
|
|
^^^^^^
|
|
|
|
There are several, important open issues with the ZNEO port (8 as of this writing).
|
|
See the TODO file in the top-level NuttX directory. One of these should be
|
|
mentioned here because it causes a failure to compile Nuttx:
|
|
|
|
Description: The file drivers/mmcsd/mmcsd_sdio.c generates an internal compiler
|
|
error like:
|
|
|
|
mmcsd\mmcsd_sdio.c
|
|
Internal Error(0503) On line 2524 of "MMCSD\MMCSD_SDIO.C"
|
|
File <c3>, Args(562,46)
|
|
|
|
Status: Open. Recommended workaround: remove mmcsd_sdio.c from
|
|
drivers/mmcsd/Make.defs. There is no SDIO support for the Z16 anyway
|
|
Priority: Low
|
|
|
|
This is bug in ZDS-II. It was discovered in version 4.11.0 and still exists
|
|
in version 4.11.1.
|
|
|
|
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-directory>
|
|
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.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configuration using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
and misc/tools/
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. By default, this configuration assumes that you are using the
|
|
Cygwin environment on Windows. An option is to use the native
|
|
CMD.exe window build as described in the top-level README.txt
|
|
file. To set up that configuration:
|
|
|
|
-CONFIG_WINDOWS_CYGWIN=y
|
|
+CONFIG_WINDOWS_NATIVE=y
|
|
|
|
And after configuring, make sure that CONFIG_APPS_DIR uses
|
|
the back slash character. For example:
|
|
|
|
CONFIG_APPS_DIR="..\apps"
|
|
|
|
NOTES:
|
|
|
|
a. If you need to change the toolchain path used in Make.defs, you
|
|
will need to use the short 8.3 filenames to avoid spaces. On my
|
|
PC, C:\PROGRA~1\ is is C:\Program Files\ and C:\PROGRA~2\ is
|
|
C:\Program Files (x86)\
|
|
b. You can't use setenv.sh in the native Windows environment. Try
|
|
scripts/setenv.bat instead.
|
|
c. At present, the native Windows build fails at the final link stages.
|
|
The failure is due to problems in arch/z16/src/nuttx.linkcmd that
|
|
is autogenerated by arch/z16/src/Makefile. The basic problem
|
|
is the spurious spaces and and carrirage returns are generated at
|
|
the end of the lines after a line continuation (\ ^M). If these
|
|
trailing bad characters are manually eliminated, then the build
|
|
will succeed on the next try.
|
|
d. Hmmm... when last tested, there some missing .obj files in arch/z16/src.
|
|
A little additional TLC might be needed to get a reliable Windows
|
|
native build.
|
|
|
|
pashello
|
|
--------
|
|
|
|
Configures to use examples/pashello for execution from FLASH
|
|
See examples/README.txt for information about pashello.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configuration using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
and misc/tools/
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. The last time I tried building this configuration, there were
|
|
a few undefined symbols from the PCODE logic. It might require
|
|
a little TLC to get this all working again.
|
|
|
|
3. The native windows build has not been tried with this configuration
|
|
but should, in principle, work (see notes for the ostest configuration
|
|
above).
