Run DMA while ICache and DCache are enables

Hello,

I read the input data over SPI DMA, but when I added the AI part ICache and DCache are enabled.

The problem is that when ICache and DCache are enabled, the SPI DMA is not working.

How can I overcome this problem?

You'd have to manage the cache coherency via Clean / Invalidate DCache by Address functions.
