Apeman A80 Firmware

The firmware translates hardware problems into visible LED blink patterns:

Apeman locked the bootloader after V0.6. If you have V0.7 or higher, you cannot flash V0.5. The firmware checks a checksum in the SPI flash. Attempting to downgrade will result in ERR_DOWN on the screen. The only workaround is to short two test points on the PCB (TP4 and GND) during boot—a micro-soldering job not worth the effort.
