- 3.3.2 Burning steps
- 1) Before burning the picture font library, make sure that the bottom layer has been burned. You can open the configuration debugging interface to connect to the code file to observe whether it can communicate. If it fails to communicate, first reset ...
- 2) After adding the files to be burned in the U disk according to the second step, connect it to the USB port of the motherboard, and then power on the motherboard.
- 3) Under normal circumstances, the display screen will start to flash and display burned pictures after a few seconds, and the U disk indicator light will start to flash.
- 4) If you cannot see the burning process, please make sure to unplug the U disk under the premise that the U disk indicator is not flashing.
