Rpi CM4 not booting

[tcikel]

Hello,

I am trying to get the ostree working on raspberry pi cm4. I am using meta-updater and meta-updater-raspberrypi dunfell branches and I have an issue with unable to boot raspberry pi.

I have already applied patch which fixed other booting issue with fit config.
My build doesnt generate any specific errors and only warnings are from missing some sota credentials.

When i ran iminfo in Uboot on my fit image I get the message that its unable to read the file but I dont think its corrupted because I tried to build it multiple times and have the same issue everytime. Its seems like there some issue with generating the fit image but I am unable to find the problem.

Hi @tcikel
I have a suggestion for you that may not solve the problem you currently have, but can get you a working version of yocto with OSTree and aktualizr installed.
There is a project called Common Torizon fully open source yocto based operating system for many embedded device and already support RPi3 - RPi4 - CM4 and many other boards.

You can start from a binary image where you need just to flash it on your module and use it:
https://github.com/commontorizon/meta-common-torizon/releases/tag/v6.3.0-common

If you need to build from source you can use the manifest, download all the met-layers, and build it, there should also be a file available in the repo describing how to build it, anyway, if you have any questions you can ask there, it is a pretty active community.
