Happy to hear from you Glen! The other day when I pulled out my Raspberry Pi 4 from the drawer, it didn't seem to be working: only the red LED comes on, and nothing else (not even the rainbow RGB screen at the very beginning of the bootloader). I am going to try a couple more things, but I think I'll order one of the new Raspberry Pi 5's in the next few days, since I saw they are only $80 + S/H.
Since I am temporarily pi-less, can you tell me in some more details what you mean with "it is tricky to start with the previous Pi4B code and go to Pi5"? Are you getting a specific error message (or messages)?
