Hi,
The DMA engine emits a lot of messages complaining of (I think) a read fault:
dma-pl330 dma-pl330.0: Reset Channel-0 CS-20000f FTC-40000 dma-pl330 dma-pl330.0: Reset Channel-0 CS-20000f FTC-40000
I'm debugging the same error right now. FTC-40000 means "Read error", i.e. invalid address of the DMA source block.
Regards, Alex
In my case it turned out the TZPC hadn't been configured properly by the bootloader. I had to modify to the bootloader to make sure the I2S was non secured (it's secure by default).
Hope this helps, Mike
