How to get debug messages from openmax components of Netra?

Hi,

I would like to know how to get debug print messages from openmax components of VS demo.

I can see debug messages up to "omx_05_00_00_11/packages/ti/omx/domx/DomxCore.c" file, which does have API DomxInit() called by OMX_Init().

The board hangs while calling DomxCore_procInit(eb) from DomxInit() API.

DomxCore_procInit() is implemented in "omx_05_00_00_11/packages/ti/omx/domx/DomxProcMgrIf_BIOS.c" file, where I tried putting printf but print message doesn't come on console.

What is the way to get debug messages at this level ?

Thanks,
Sweta

    Try  System_printf

    Hi Eric,

    Thanks for the quick suggestion.

    I tried System_printf but I am not getting any message on debug console.

    Do I need to perform any special step to enable System_printf() ?

    Reason is, I want to enable all debug messages from "omx_05_00_00_11/packages/ti/omx/comp/ctrl/src/tvp/omx_ctrl_tvp_if.c" file.

    This file does already have System_printf() for necessary checking but I am not able to see any of the messages.

     

    Please help me if I have missed anything.

    Thanks,

    Sweta

    I your question concerns messages from DSP side and at least you're using CodecEngine: for me the Log_print1, Log_print2, ... functions worked, I got their output on ARM side by calling the application with CE_DEBUG set before, like calling "CE_DEBUG=2 ./myapp".

    If that produces too much output, you can limit that to the output from explicitely named modules only, for that see this entry by Chris.

    Sweta,

    It is possible to use a new module called UIA to get these trace messages accessible by the A8 via a shared memory block. I've been using it on the VC3 demo from 5.0.0.11 successfully. I've attached the instructions on how to access UIA and then how to use it.

    Iain,

    I was actually interested to know

    • where that sdk 5.0.0.11 can be downloaded,
    • if it is an earlier version of the current EZSDK 5.01.01.80 and 
    • if it is less buggy than EZSDK 5.0.0.59 and
    • if it has any actual advantages comparing the current EZSDK.

    That is because this SDK version is often spoken about here in the forum, but I couldn't find any substantial information about that point.

    Additionally it would be fine if the document you provided would be available also within a less proprietary format than just from Winword 2007 - although OpenOffice is able to read it I find it was more convinient to provide it either as PDF or in an actually open format like ODF.

    Thanks in advance,
    best regards,
    Joern.
