Black screen on a bare metal Raspi installation

Hi bzt :)

I'm not sure if it's a real issue with MEG4 or more my very own inability, but I can't get MEG4 run on my Raspberry Pi.

I compiled it as descriped in platform/raspberrypi/README.md on my raspberry, moved the generated .iso to my computer, put it on a sdcard using dd, put the sdcard in my raspi, turned it on and just got a blank screen.

So I edited cmdline.txt, removed "quiet" and tried it again.

Now I can see Linux's startup messages until my screen turns black again.

Maybe you got some further ideas what I could try to make it work.

Used system: Raspberry Pi 3 Model B V1.2

Thanks in advance & cheers nics_le
