Have you considered using the standard DFU method to signal a firmware upgrade during normal operation? You would just export a run-time descriptor set for DFU additionally to your normal USB interfaces during run-time. Over this interface you would signal a DFU_DETACH to EP0 and the host would reset the device to come up into DFU mode for flashing (Chapter 4.1 and 5 in the DFU 1.0 spec). I know you must have read the spec thats why I wonder why you wrote the tools to do these steps outside of DFU. Any problems you did run into? From a dfu-util point of view I want to support such setups and therefor would be interested if you did run into problems. regards Stefan Schmidt _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
