I am developing a custom camera application derived from the UVC example. I don't need to insert the UVC header for my application, so the CPU does not need to be interrupted to modify the Bulk transfer data on DMA commit. I'm trying to get rid of the Callback by using the DMA in AUTO_MANY_TO_ONE. However the host always reports failed Xfers (0 bytes received) unless I alter the data count value(partially corrupted data due to some skipped bytes in between, but at least I get something). I include my DMA Channel and GPIF setup, maybe I'm just doing something stupid or missing something.
