ZDS-II Compiler Versions
^^^^^^^^^^^^^^^^^^^^^^^^

Different configurations have been build for this board using ZDS-11
Versions 4.11.0 and 4.11.1.  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

  Although it compiles without error, the 4.11.0 compiler generates
  This is the only version that this code has been built 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.

Other Versions
  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/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.
