Hi, I am a beginner of AIF on C674, and I download a example project from http://www.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber= sprab58, to meet my requirements, I changed the code a little bit to fulfill an unidirectional transmission from DSP1 to DSP2, and it works. But when I try to trigger another transmission in which DSP2 transfers those data back to DSP1, it never works. Here is my project, anyone knows where is the problem?

Hi Yang,

I am also trying to run the CPRI AIF on the EVMC688. But I see that the Recieve task not getting called. This means that the EDMA transfers not happening. I have use the interdsp example code shared by TI. I have tried both loopback & non loopback. Can you pls tell me if you had done any changes to the example code to make it work ?

Also you have any idea as to why its not working in my case ?

Regards,

Tejas

    Tejas,

    Please edit this new thread's title to be accurate for your question. Also, please correct the EVM part number since the one here is not valid.

    If the correct part number is EVMC6488, then this is a device that is not supported on the E2E forum, but via direct support with your local FAE. Your local sales office or your company management may be able to point you to the correct resources, in that case.

    On the EVMC6474, the example code from TI works as delivered. I do not recall having to make any changes to get it to work, but it was a few years ago that I used this.

    Regards,
    RandyP
