syslink 2.20.00.14 examples don't work (OMAPL138)

The 2.10.06.28 samples worked fine for me, but the latest do not.

For example, messageq:

    Elron,

    In SysLink 2.20, the examples in ti/syslink/samples, have been replaced with platform specific archives.  There is a readme.txt file in

        <SYSLINK_INSTALL_DIR>/examples/archive

    that describes how to build the examples.  You will find the example .zip files for the OMAPL138 in:

        <SYSLINK_INSTALL_DIR>/examples/archive/OMAPL138_linux_elf

    Best regards,

        Janet

    Janet,

    I saw the new examples, but my problem is with the older samples (in particular a  sample which I imported into CCS and modified a bit).

    I had missed the compatibility section of the syslink release notes, so after I downloaded the latest ipc, bios, and xdc I made some progress.  (It would be nice if all  downloads were in one place.) 

    After some debugging, I found that the new version of ipc has some semantic differences (undocumented as far as I can tell) from the previous-- some functions which were safe to call from main now can only be called from a Task.   There's also some difference in sysbios behavior when the last Task exits, but rather than figure out what's going on, I just changed my code.
