Hi guys.
i did a stupid move by powering my usb hub pluged on orangepi with my dc adapter set to 9v insted of 5v XD.
it is not working anymore.(armdian buster)
i have green d7 on, and both rj45ligth on.

i check some of the compenemt but found nothing.
do you know a way to troubleshoot it? can i monitor boot with tx rx pin or other way?

I think it may be damaged beyond repair, but power off  and leave it a few hours
to make absolutely sure no residual charge exists.

If you can check your sd card in another linux system run a filesystem check to make
sure card is ok.

On my Orange Pi zero  with no card and power applied I get ethernet LEDS lit and no green
power light. With a bootable sd card the green power light comes on after 2 or 3 seconds and loads normally.

I think though this is perhaps damaged beyond repair.
