Hello,

If you are interested, I got it working. An IRQ to remove in the device tree. This is an early post, I have to use my port to see if reliable, and understand why I needed to remove this IRQ which is not present in Raspberry Pi5. I think I'll post on OpenWRT forum rather than here, to share more widely.

Hi,

I made one more test trying the Raspberry OS lite with the carrier board. I managed to boot and connect to network, apt update and upgrade, with both ethernet ports.

This brings me to the fact that hardware part is working fine, with no incompatibility between the router mini board and the CM5. So I guess I'm only facing SW issues. Still investigating…
