Experts, I have made a set of boards (AWR 1243) according to your evaluation boards, but PC can't identify the xds110 (tm4c1294ncpdt) as the two serial ports “XDS110 Class Application/User UART (COMX)” and “XDS110 Class Auxiliary (COMX)”,but “Stellaris Device Firmware Upgrade”. So that the set of boards are not working. I think a dedicated firmware is needed for the tm4c1294ncpdt. Can you provide me with this firmware and tell me how to use it? I will be very grateful.
