Could not wait and made my tests right now. Result: Negative!!!

I downloaded the latest miniroot78 image from yesterday and wrote it
onto 3 different devices: sd card, usb-stick and nvme ssd.

However the result was always the same: the raspi started up and ended
up by displaying the little u-boot image top-right on the screen.

Nevertheless I established a serial connection to an amd64 machine
running also OpenBSD (7.7). Before I have doublechecked that the debug
uart of the raspi was activated - it was. But there was nothing what
comes over the serial connection - absolutely nothing.

I don't have a debug probe but 2 special serial cables for the Pi 5. I
tested both cables, and, believe it or not, I tested on 2 different
raspi 5. No chance at all.

Maybe I made a big fat mistake, but I don't no wahts going wrong.


For toady I will give it up.

Regards
Berni
