Why then do all of the error messages refer to ESP32 ?
oh ok you right, sorry i try to update the firmware with another example, the firmware updater of Wifi101 but i have the error "make sure that firmware updater sketch is loaded on the board".
Make sure that FirmwareUpdater sketch is loaded on the board.
