EVM6678L DSP loading application

Jie Liao-
Intellectual 635 points

Dear all,

   I was using Desktop-linux-sdk to use the TMDXEVM6678L board via PCIe connection with PC. According to the demo which comes along with this sdk, it sends a test file from host to dsp and dsp makes a copy to send the same file back. My question is that if I send an application file to DSP but rather than let DSP make a copy of that application I want to run that application on DSP, what should I do to achieve this? I didn't see any clue from the desktop-linux-sdk development guide, thank you so much if you can help.

Regards,

Jie

    Hi All,

      As I was using the TMDXEVM6678L board to offload the computation task from host CPU, I connected the board via PCIe with the PC and used Desktop-linux-sdk to load binary file to the DSP. According to the demo application coming along with the SDK, a binary file can be sent from host the DSP and retrieved from the DSP to host. If I want to run some application and I use the same method to load the application firmware to DSP, how can I inform the DSP that this is an application which I want to run it and get some results back?

      As with the same board but connected via JTAG to the PC, I can use CCS along with MCSDK to write code, compile it and load it to run on the DSP. I was wondering what APIs which CCS provides inside it to load the application and get the results back after it's run on DSP? Is it the similar thing as the desktop-linux-sdk? Or something similar to previous kernel driver support DSP Bridge which support c64+x cores on omap3/4? 

      Thank you very much for your concern,

      Jie

    Hi Rajasekaran,

      Thank you for your kindness. I'm really looking forward to your replies, I searched a lot over google, but still got very little information on this.

    Hi Jie,

    The Desktop Linux SDK demo can be used as a starting point to develop applications.

    If you want to develop applications using the Desktop Linux SDK. Porting the existing demo application and use it.

    Thanks,

    What do you mean by "application file"?
