If edma_terminate_all() was called while a transfer was running (i.e. after edma_execute() but before edma_callback()) the echan->edesc was not freed. This was due to the fact that a running transfer is on none of the vchan lists: desc_submitted, desc_issued, desc_completed (edma_execute() removes it from the desc_issued list), so the vchan_dma_desc_free_list() called at the end of edma_terminate_all() didn't find it and didn't free it. This bug was found on an AM1808 based hardware (very similar to da850evm, however using the second MMC/SD controller), where intense operations on the SD card wasted the device 128MB RAM within a couple of days. Peter Ujfalusi: The issue is even more severe since it affects cyclic (audio) transfers as well. In this case starting/stopping audio will results memory leak.
