Ravi Terala Posted November 9, 2023 Share Posted November 9, 2023 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? 0 Quote Link to comment Share on other sites More sharing options...

I hope your powered hub didn't send anything higher. Try a 5V PSU instead. 0 Quote Link to comment Share on other sites More sharing options...
Ravi Terala Posted November 9, 2023 Author Share Posted November 9, 2023 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? 0 Quote Link to comment Share on other sites More sharing options...
royk Posted November 11, 2023 Share Posted November 11, 2023 @Ravi Terala Read the manual, there you can see how to use the UART, mind the baudrate capability of the adapter. 0 Quote Link to comment Share on other sites More sharing options...

Jaybyrd Posted November 12, 2023 Share Posted November 12, 2023 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. 0 Quote Link to comment Share on other sites More sharing options...
Ravi Terala Posted November 27, 2023 Author Share Posted November 27, 2023 @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? 0 Quote Link to comment Share on other sites More sharing options...
Ravi Terala Posted November 27, 2023 Author Share Posted November 27, 2023 I guess the board might have been fried. No power shows up on any where. 0 Quote Link to comment Share on other sites More sharing options...
