Hi,

I'm working on TDA4VH with sdk0900, and I want to use DMA to transfer data.

But, when I use DMA to transfer data to the DDR obtained from the system memory, c7x gets stuck.

The current data size to transfer is 83072 bytes.

I use the following interface to obtain DDR memory：

I have obtained a total of 498432 bytes of DDR space.
