Part Number: AM6442

Hi

I'm interested in archiving core-to-core DMA by using queue or ring. The keystone multicore navigator has the infrastructure packet DMA for the purpose, but I didn't find similar description in UDMA manual. Does this function supported in UDMA, or can be achieved through an alternate way?

    Hello Wen,

    Why can't you go with BCDMA for your requirement?

    You just wanted to transfer data from one core to another, and it should be possible with BCDMA as well.

    Can you please confirm you wanted to transfer data from which core to which core?

    Regards,

    S.Anil.

    Hi S.Anil,

    Thank you for your reply. I may need to think about this issue myself. Let me familiarize myself with BCDMA.

    If there are problems later, I will open a new thread and this thread can be closed.

    Best Regards

    Wen
