Lewis, Sorry for the lack of communications from TI side here; not sure if you have any updates from your side. Have you been able to put a scope on the serial pins to compare what is transmitted from the host to the C2000 vs what the C2000 sends back? Trying to see if there is a error on the bus that real, vs something that is not getting captured correctly by the host and then C2Prog throws an error. FWIW there are no changes to this device that I am aware; any other changes to your overall system that we should consider, i.e. new PC host or new USB to RS485 converter, etc? Best, Matthew
