Hi, Here is some debug output I captured showing a problem I am having with the file backed storage driver.
In English, what appears to be happening is the host sends the mode select(6) command, which is not supported by file_storage.c. The response causes the bulk-out ep to be stalled nd the fifos flushed. The error response is sent and an empty buffer is queued to receive the next bulk-out data. check_command okay do_mode_select: entry do_scsi_command: error reply length finish_reply: entry finish_reply: fsg->data_dir 1 bulk-out set halt set_halt: ep1out-bulk set halt finish_reply: returning -4 ep_fifo_flush: entry: ep1in-bulk ep_fifo_flush: entry: ep1out-bulk sending command-failure status ep_queue: ep1in-bulk queue req 02caafa0, len 13 buf 05eac000 req_done: complete ep1in-bulk req 02caafa0 stat 0 len 13/13 bulk_in_complete --> 0, 13/13 ep_queue: ep1out-bulk queue req 05e271a0, len 64 buf 05ea8000 read_fifo: ep1out-bulk len 0, storing at 0x05ea8000 space 64 The problem I am seeing is the next bulk-out data that is received is responded to with a stall, because the file_storage.c driver didn't call the UDC set_halt() function with a clear stall indication. Am I missing something or is one of the other UDC APIs (like flush or queue) suppose to also clear the stall?
