Same porblem here. I've burned the newest firmware and use 1.8.3. Only function woks, is on/off, invert. I cannot change what to display.

I am beginner of M5Stack. I bought both M5Go and Fire, together with lots of units. When I test the OLED unit, I found it always show M5 logo with "M5STACK". i can 't fill with black or white. I can't draw rect. I can't draw line. I can't draw text. The only function works is "invert" but still only M5 logo with "M5STACK" is shown all the time. I tested it with both M5Go and Fire but same problem. Any help?
