I have an SD-Card Image for a Pi Zero but the Pi Zero was always a bit slow for the task (Web-Server, Machinelearning). So I would now like to replace the Pi Zero with a Pi Zero 2 W.

Unfortunately, the Pi Zero 2 W does not boot from the old image. No LED turns on and I get the rainbow square on HDMI output.

  • What is so different between both systems?
  • And do I have a chance to modify the old image to be able to run on the Pi Zero 2 W?

PS: I already tried to create a new image, leave the boot partition as is and copy the file from the other partition over. No success.

PS: did a sudo apt-get update, upgrade and dist-upgrade. seems I have debian stretch on the system...

If you have a fully updated 32bit Raspberry Pi OS Bullseye or Buster SD Card it will work in ALL models.

You should update on your existing Pi.

Attempting to use an older OS will NOT work even if you try to update kernel and firmware.
