Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O itself. This could happen due to problems with the storage medium, or simply when trying to write a FAT/ext file that is larger than the buffer dfu_mmc.c maintains for this purpose. Signal the error by switching the DFU state/status. This will be picked up by the DFU client when it sends the next DFU request. Note that errors can't simply be returned from e.g. dnload_request_complete(), since that function has no way to pass errors back to the DFU client; a call to dnload_request_complete() simply means that a USB OUT completed. This error state/status needs to be cleared when the next DFU client connects. While there is a DFU_CLRSTATUS request, no DFU client seems to send this. Hence, clear this when selecting the USB alternate setting on the USB interface. Finally, dfu.c relies on a call to dfu_flush() to clear up the internal state of the write transaction. Now that errors in dfu_write() are detected, dfu_flush() may no longer be called for every transaction. Separate out the cleanup code into a new function, and call it whenever dfu_write() fails, as well as from any call to dfu_flush(). Signed-off-by: Stephen Warren <swarren@nvidia.com> |
