According to this I cleaned up my workbench yesterday, took another Pi5 (the third one), wrote a new miniroot78.img onto a totally new sd card and brewed a big pot of coffee. Then I started again, at first with an EDK firmware sd, because with that the Pi always booted. 1. Boot via EDK, select the image sd at usb,entered "set tty fb0" and OBSD boots up into HDMI to the installation menu. There system hangs, no keyboard, finito. 2. The same without "set tty fb0", debug probe is connected to another OBSD machine - and I got the boot output to the serial, as above up to the installation menu. There the system hangs, no keyboard. So using EDK firmware seems to be not the best way. 3. Now the newly written image sd into the mmc slot, a new nvme ssd into the HAT. No "set tty fb0" because now I knew that the serial works. Had wonderfull output into the serial, system booted and I was able to do a complete installation on the nvme ssd. Unfortunately the system on the nvme did not boot but hangs with the u-boot logo on the screen. Finally I prepared a special installation on a 64GB sc card via a Pi4. The installation was minimal with a big / and very small /usr/local and /home. This sd card booted perfectly and I now could create new partitions for /usr/local and /home on the nvme ssd. So I now have a running system, till now without problems. Today I will make some tests and will then build another Pi5 system, running as a camera server with motion and mpv. Thanks to this wonderfull mailing list and the great help. Without this assistance I probably had given up. Regards Berni
