Rock 3A electrostatic on GPIO

#1

Hi, I touched a GPIO output casually on Rock3A, and I felt an electrostatic shock.
Now I try to give various commands on any output but nothing, I don’t get any voltage on the GPIO pins, the main voltages 3.3V - 5v - 1.8V are all present.

Is it possible to repair the GPIO stage, can I do something?
Help me.

I believe the GPIO block of the SoC is damaged, this can only be repaired by replacing the SoC chip. I suggest you leaving it running with other features without GPIO.
