I bougth Core2 + Faced RFID. With FlowUI I can get all work, but I want to make some Arduino code, because want to have faster boot, FlowUI have own boot logo etc.

If I use M5Stack library Core2 wont boot.
If I use this code wont work: https://github.com/m5stack/M5Stack/blob/master/examples/Face/RFID/RFID.ino

Only M5Core2.h working, but cannot get RFID to work.

Have anyone tried this?
