OMAPL138 Sysink IPC

Other Parts Discussed in Thread: SYSBIOS

Hello

I am investigating code that runs on the OMAP138. The code runs wireless application. Engineers who wrote  the OS  including SysBios and SysLink and IPC are no more available. The code runs OK. SysLink and IPC uses MessageQ and Shared Memory, I need to know from the IPC source code at which point the DSP signals to the HOST (ARM) to take data from the Shared Memory and vice versa, I would like to know the functions and the line of code that does such thing in each direction between the DSP and the ARM. This is needed to measure some timings.

I hope my question is clear. I appreciate any hints.

    Hi Hatem,

    It depends on which version of Syslink you use?
    Do you use any sample IPC examples from the package?

    I would recommend you to go through the following links and understand the overview of the Syslink and then accordingly, browse through the source code.

    What version of IPC is used?

    For understanding the MessageQ , please have a look at this WIKI.

    Hi Shankari,

    Thanks for the reply.

    I went through the links, good overview information.

    I browsed through the source code, the code is not commented. and I found it difficult to find which is which in the code.

    The version used in the code is   syslink-2.20.00.14.

    Hope may be useful to pin point the required function or file.

    Regards

    Hatem
