Device not booting with any Image

I can take any of the provided example images or my own yocto build, I always end up with this console output:

The console seems to be crashed, as I cannot enter anything through serial.
Any ideas?

Did you try the latest images available in DH wiki: https://wiki.dh-electronics.com/index.php/Avenger96

If you are talking about this: https://www.dropbox.com/s/nffk6xgm91ysqf3/dh-image-demo-dh-stm32mp1-dhcor-common-avenger96_2020-09-04.wic.xz?dl=0

Then yes!

Okay. Did you try the OpenSTLinux image?

I just retried it. It lead to the exact same behaviour.

Btw: the serial output does not look exactly identical for the two, but they end the same way. The dh-core image produces the following console log:
