Hi mikhailtchernychev , did you ever find a solution for your issues? I’m facing the same right now. Thanks, Valentin

No, we stopped evaluating Rpi4. I only could make work image from May 2020.

Can anyone confirm of a distro + image recipe working? When I boot my raspberrypi4 B it does not give any error but I also don’t have access to SSH nor the monitor. I am building core-image-base on dunfell

I got it to work in the meantime, I think it works because I set ENABLE_UART = “1”.

Could you share which other changes you made? Which Yocto Version, for example

We are using dunfell and our config roughly looks like this: # local.conf # --- hardware support MACHINE = "raspberrypi4" DISTRO ?= "poky" INHERIT += "rpi-update-firmware" # # --- mender stuff MENDER_ARTIFACT_NAME="xxx" MENDER_SERVER_URL = "https://hosted.mender.io" MENDER_TENANT_TOKEN = "xxx" …
