Because It's weekend and I have no means of aquiring an adapter for the tiny HDMI connectors on the pi4, I put the freshly made SDcard, with the current Raspi OS, 64bit, no desktop, into the Pi3 first, to enable SSH, so I'll be able to remote connect when using the Pi4 without a monitor/keyboard directly connected.
This works so far, the Pi4 starts and can be accessed from SSH.
The raspinfo.txt, which presumably is created on the first start, still shows Raspi3 info.
Also, htop shows only 1GB of RAM... but lowest RP4 models have at least 2GB? (I'm don't recall what this one has),
I guess the detection of the model is done in some run-once-only script(s) at first start.
Can I rerun that stuff?
Or will that axe my SSH settings and I'm back at square 1?
