Hi @amnj86,

You did not mention which Yocto version you are building.

For reference, you could try [Raspberry Pi 4 Model B - #2](https://hub.mender.io/t/raspberry-pi-4-model-b/889/2).

This is very strange and could explain the problems you are having.

Do you post-process the rootfs image after the Yocto build in any way?
