I have a rock3-cm3 v1.32A (D8E32W) that I had put debian on a long time ago. I tested it and it seemed to work just fine on the rpi cm4 io board. But when I tried using RKDevTool to reflash the eMMC, the board no longer does anything when powered on normally (no HDMI output, no green led). RKDevTool seems to write to the eMMC just fine, but when I try to boot the board normally, nothing happens. It seems like the board is stuck in maskrom mode, and the green led will never come on. Did I brick my cm3? Is there any way of fixing this? It’s possible I am doing something wrong when writing to the eMMC. I have been following these instructions: https://docs.radxa.com/en/compute-module/cm3/low-level-dev/maskrom/windows. Any help would be appreciated.
