Initially, my maple Mini board's LED do not blink at all and program could not upload to the board, it show "Couldn't find the DFU device: [1EAF:0003]" error. Then I followed the instruction to flash the MCU and get the flash verification OK. However, the LED on the board now do not flash after reset, it keep OFF all the time.
In the device manager, it does show up a new COM port "Maple R3 (COM23) but the download still fail. same error message "Couldn't find the DFU device: [1EAF:0003]"
Any idea? thanks!
Here is the Flash screen shown. Was that a correct flashing process?
