Just wondering why my attempt to move a working headless Fedora 34 build from a 2 GB rpi4 to a 4 GB rpi4 fails even to boot. In fact, it never even puts out the steady red LED. I copied the micro SD card (from the 2 GB pi) directly over USB and wrote the build to another SD card using dd using a set of commands that has always been reliable in the past.
Any thoughts, please?
