Rock 5C does not boot

I’m having trouble getting my Radxa 5C to boot, and I would really appreciate your help troubleshooting the issue. Below, I’ve included all the relevant details about my setup, the problem, and what I’ve tried so far. Please let me know if I missed anything that might help diagnose the issue.

Setup Details:

Rock 5C (brand new from a package, no signs of damage)
Power Supply 5V 3A
SD card 32 Gb (works with Radxa 5A
OS: https://github.com/radxa-build/rock-5c/releases/download/rsdk-b1/rock-5c_bookworm_kde_b1.output.img.xz

The Problem

  • Symptoms:
    • Solid green led all the time, no blinking
    • No messages on serial debug port
    • Board is always cold, temperature does not increase after 20 minutes

What I Tried

  1. Power Supply:
  • Verified the power supply works with another device.
  • Tried a different power supply to rule out issues.
  • Tried to supply power from a laptop and powerbank
  1. OS

Questions

  1. Could this be an issue with the OS image or bootloader?
  2. Is it possible that the hardware is faulty, and how can I confirm this?
  3. Are there additional diagnostic steps I can take?

Did you unzip the image before burning it?

Yes. At first, I tried to burn a zipped image, but after rereading the post about common mistakes, I unzipped all my images and tried again, but it did not help.

Make sure you used 1,500,000 baudrate for the UART. The Rock 5C has a socket for eMMC/SPI flash. If you have one fitted, remove it to make sure it is not preventing your SD card from booting.

You can also try maskrom mode (check the documentation) to see if your device replies to rkdeveloptool/rkdevtool commands. This would prove/disprove if your device is dead.
