Basically, the device is working.
I prepared an SD card with RPI Trixie using the PI imager.
Modified "/boot/firmware/config.txt":
Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2
dtoverlay=vc4-kms-dpi-hyperpixel4sq
dtoverlay=hackberrypi
Using the SD Card Copier I prepared a m.2 nvme drive.
Booting worked initially.
Next I connected an external monitor and a keybord for better handling 😉.
After a power cycle booting without the external monitor showed a blank screen.
Connecting wireless showed the device is still using the external monitor "noop-1".
Surprisingly, when booting with the SD card inserted it uses the internal monitor,
which may work as workaround for the moment.
If I can be of help, please tell me.
Kind regards
