ZDS-II Compiler Versions
^^^^^^^^^^^^^^^^^^^^^^^^
Different configurations have been build for this board using ZDS-11
Versions 4.11.0, 4.11.1, and 5.1.1 You have to check the files */Make.defs
to see how the build is configured: Check the definitions of
ZDSVERSION (if present) and ZDSINSTALLDIR.
NOTE: Different versions of the ZDS-II compiler may also require
different versions of .linkcmd and .zdsproj files as well.
Version 4.11.0
The 5.1.1 version of the ZDS-II tools are currently configured for
all ez80 boards. However, it is the older version 4.11.0 that this code
has been verified against.
Although it compiles without error, the 4.11.0 compiler generates
bad code on one of the files, mm/mm_initialize.c. Below is a simple work-
around.

UPDATE: I don't know if 4.11.1 has this same problem (I bet not since
I submitted the bug to ZiLOG), but I have permanently worked around the
above problem for all ZiLOG compilers.
Version 5.1.1
On June 22, 2011 I verified that these configurations build successfully
with the 5.1.1 ZDS-II version. On November 12, 2012, all of the configurations
were converted to use 5.1.1, but have not been verified on a running target.
The above kludge for 4.11.0 is not required with 5.1.1.
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 5.1.1 or if you install ZDS-II
at any location other than the default location, you will have to modify
two files: (1) configs/ez80f910200kitg/*/setenv.sh and (2)
configs/ez80f910200kitg/*/Make.defs.
Configuration Subdirectories
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- src/ and include/
These directories contain common logic for all ez80f910200kitg
configurations.
Variations on the basic ez80f910200kitg configuration are maintained
in subdirectories. To configure any specific configuration, do the
following steps:
cd <nuttx-top-directory>/tools
./configure.sh ez80f910200kitg/<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/z80/src/nuttx.linkcmd that
is autogenerated by arch/z80/src/Makefile.zdsii. 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.
Check out any README.txt files in these <sub-directory>s.
