Hi,

I want to move memory from A to B.

The DMA code works properly on TDA4VH with 0805SDK, but it does not work on TDA4VH with 0900SDK.

No errors were reported during runtime.

Are there any important modifications to DMA in the 0900SDK?

Hi,

No, it should just work fine. On which core are you seeing this issue? Are there any debug logs that you can enable to figure out where exactly the issue is?

Regards.

I am using DMA on C7x. I have observed the logs of C7X and there are no error messages in the logs.

Hi jinsong yang,

Are you sure that it hangs after submitting the request to the DMA and there is not interrupt? Can you please put breakpoint on the interrupt callback and check if there is any callback?

Regards,

Brijesh
