If I put an updated Raspbian into an older Pi 4 will it update the firwmare?

That's really my only question. I have a primary Pi 4 and a secondary one both purchased around the same time. I use the secondary one for other OS's and experiments. If I move the SD with my fully updated Raspbian from my primary to my secondary will it update the firmware or do I need to do something to make it happen? Running apt-get update/upgrade doesn't seem to actually do anything when it's up to date even on an older pi.

If it you don't have NOOBS 3.1.1 or Raspbian Buster 2019-06-20 (or later) on your SDCard it won't boot on your RPi4B and there's no simple (or supported) way to upgrade anything older.

I guess you want to update the bootloader and the VLI EEPROM to the latest stable versions. If the rpi-eeprom-update service is enabled, you will need to boot the Raspbian two times. The upgrade process will be performed at the second boot.

He indicates that both are Pi4Bs, so he has to be running Buster on the one using Raspbian.

At present, I don't believe that firmware updates are automatically done through the apt update/upgrade process. That is planned for the future. The way thing are now you'd have to explicitly tell the Pi to upgrade the firmware.

I've definitely received the update that unlocked the overclock multiplier that way.

Changing the overclocking limit doesn't involve any firmware in the EEPROM.

Alright
