Hi, I just bought a CM5 along with the CM5 Dev Kit.
I flashed it using rpiboot and installed Ubuntu 24.04. Everything went well during the installation, but when I tried to use it, the LED error pattern indicated a fatal firmware error.
I then tried to flash it with Raspberry Pi OS to check if the problem was specific to Ubuntu. rpiboot worked fine—it detected my CM5—but the CM5 did not appear as a storage device, and the green LED only lit briefly during rpiboot before turning off.
Has anyone successfully booted a CM5 with Ubuntu 24.04?
Also, why am I unable to flash my CM5 with another OS?
Thank you !
