What's wrong with my Rock PI X?

hey guys:
I have some problem with my rock pi x. when I power it up, it just flash the LED and output nothing on the screen. I can’t enter the BIOS either. I don’t know what to do. Sorry to my broken English:(

What was the latest thing you did with your RockPi?

It turns out he is using the Huawei Fast Charge, which protocol is not supported by ROCK Pi X, so the output is 5V, not enough power.

Good to know!
i tryed to use it on a RPi4b 1.3 and after this i need to replug the original PS 10 times to get my Pi4 back to work again. Somthing must be realy different in the Huawai P30Pro Fast Charger.
