I have an old image from my Raspberry Pi 2 (Jessie Lite) and this works fine on my Raspberry Pi 2 running the BCM2836 processor, however I ordered a new Pi 2 and it seems that they have changed to the BCM2837 processor for the Pi 2.

When I boot the same SD card on the new Pi 2 it gets stuck on the rainbow screen.

I know I need to do an update using the old Pi 2 to get it to work on the new Pi 2, but what command do I need to update the absolute minimum for this to work?

  • How much work is sudo apt update && sudo apt upgrade? – Milliways Dec 19 '16 at 22:28
  • The problem with that is it updates all packages, not just the one that is required for the boot. – Sean Bulley Dec 19 '16 at 22:30
  • Not upgrading other packages is a big security isssue. – Steve Robillard Dec 20 '16 at 2:46
  • Yes, while not upgrading everything is not advised... for this instance, that's not an issue... Only getting the image to boot is the requirement. – Sean Bulley Dec 22 '16 at 11:06

I have no idea how you might minimise the changes.

I would use the following command to update the firmwaresudo rpi-update.

Problem was with the Kernel, to repair this without updating packages you don't want to touch run.

apt-get update
apt-get install raspberrypi-bootloader

This will update the bootloader package to the latest version without changing anything else.
