Using C6748 on OMAP-L138 LCDK EVB

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

Hi,

I would like to debug my C6748 software on the OMAP-L138 LCDK EVB.

I configured the DSP initialization script to run the OMAP138_DSP.GEL fie.

It seems that the ARM is running and interfering with the DSP initializations.

Can you guide me how to configure the connection to the board and debug the DSP application (including access to the H/W modules) when the ARM is not interfere?

Thanks.

    Hi Eyal Lahat,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics.

    When connecting the ARM + DSP cores in the OMAP-L138 LCDK, follow these steps:

    1. Load the OMAP-L138_LCDK.gel file.
    2. Launch the Target Configuration created above.
    3. Select the top line of ARM9_0 and right click Connect Target.
    4. Select the top line of C674x_0 and right click connect Target.
    5. Now you are Ready to start loading code and start debugging.
    Please refer below link for more detail:

    Hi Eyal,

    You would definetly be able to run the C6748 software on OMAP-L138 LCDK and also debug using CCS provided the gel files are correct and the wake up sequence of ARM and DSP are followed correctly.

    To be specific, OMAP-L138 is a ARM boot device. The ARM will wake up first which in turn wakes up the DSP. If you provide the OMAPL138 LCDK ARM GEL file, it will bring the DSP out of reset and the application can be loaded using emulator and run on OMAPL-138 LCDK

    Here, you mentioned " C6748 software". Not sure whether it is the demo software or your own? My suggestion for you is to try out the demo softwares ( For example: Face detect demo) already available which runs on OMAPL-138 LCDK. It is always good to start from something which already works.

    Please let us know how it goes and what you observe from it.

     

    Regards,

    Shankari
