My C4 refused to boot from eMMC, the screen on TV shows blank, no active source. I can’t even get to the HK logo. I performed the RC3 update yesterday, things went smoothly and no issues then.
Is there a button on the board to reset or short pin something?
No booting from microsdcard also, same thing: red light at IR and lights at RJ45, nothing else.
I have an usb TTL board CP2102, how to get an uart log?
