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-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.

Check out any README.txt files in these <sub-directory>s.
