Hello everyone, this is my first attempt with piCore on a new Raspberry Pi 4. The Pi 4 works fine with Raspbian, but I have tried piCore 9.0.3 and then 8.1.5 on the same SD card and each time I get no video signal.
HDMI cable is plugged in the same port as when Raspbian works. I've tried two monitors, both work with Raspbian, neither with piCore.
From what I have read, I am expecting to see a prompt on screen when the Pi 4 starts up, but I get no video signal. Grateful for any help, am I missing something obvious?
