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.

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

Thank you! As I'm the one who ported the bootloader (barebox) to S5PV210, I think I should support generic TZPC configuration in the bootloader.
