Also tried treating DMA_CB_STATUS_SPLIT in a sense but that leads to IPC timeouts and a sort of hanging (when aplay stops due to the timeout the firmware seems to acknowledge and recover).
Hi all,
We pretty much understood the meaning of dma_cb_status.
Now we want to understand when the one needs to call
DMA_CB_TYPE_IRQ vs DMA_CB_TYPE_COPY?
Can you help? A document describing the DMA workflow would
be nice to have :).
thanks,
Daniel.
