Orange Pi 5 power issues

[Ravi Terala]

My Orange Pi 5 appears to be completely dead. No lights turn on when the power is connected and the SD card is freshly imaged as well. This started happening when I connected a USB-C multi-port dongle with a connected PD power supply to it. Is it possible to revive this?

It doesn't have pd, only 5V. I hope your powered hub didn't send anything higher.
Try a 5V PSU instead.

I wasn't using PD, was using the plain old 5V 4A power supply I was using earlier. The board was already powered up with the 5V-4A power supply when I connected the USB-C multi-port dongle. Is there a way to diagnose what went wrong? Is the board totally dead?

@Ravi Terala Read the manual, there you can see how to use the UART, mind the baudrate capability of the adapter.

Make sure you have the adapter set to 3.3V and you only need 3 pins. The ground goes to the ground, but then you need transmit (Tx) to receive (Rx) and receive (Rx) to transmit (Tx). I use minicom in a Linux terminal with baud rate set to 1500000 and the adapter will be located on /dev/ttyUSB0. To adjust those settings in minicom,

"sudo minicom -s" and save as dfl. You can also give your user permission to use minicom without sudo. "sudo usermod -a -G $USER dialout" then log out and log back in.

@Jaybyrd, @Werner I tried the maskrom process and nothing is detected. I tested all the pins using a multimeter and no voltage is detected on any of the pins. Is this board now completely dead? Any way to revive this?

I guess the board might have been fried. No power shows up on any where.
