I’m using a Radxa CM5 with a CM5 IO board. I flashed an image to the CM5’s eMMC with RKDevTool. The flash appears to complete successfully, but after power-cycling the IO board I don’t see the expected blue LED blinking and the system doesn’t seem to boot.
My setup and exactly what I used (followed the official guide as-is):
- CM5 revision: V2.21
- CM5 IO revision: V2.2
- Image: radxa-cm5-io_bookworm_kde_b3.output.img.xz
(downloaded from: [https://docs.radxa.com/en/compute-module/cm5/getting-started/download) - Bootloader: rk3588_spl_loader_v1.15.113.bin
- RKDevTool: v2.96
RKDevTool reported that the image was written to eMMC successfully. Here’s the log:

After power-cycling the board, the blue LED does not blink and there’s no sign of boot.
Questions:
- Is there any additional step required after flashing to eMMC for this image and board revision?
- Should I be using a different bootloader or image for CM5 V2.21 + CM5 IO V2.2?
- Is the blue LED expected to blink immediately on a normal first boot, or only after some point in the boot process?
If I should collect serial console logs or try a different procedure, I’m happy to provide more info. Thanks in advance.
