Need manually applied firmware update when insert JP4.5 updated SD-card?

I have a couple of jetson development boards and use one sd-card image for all.

I updated the master-image to jetpack 4.5 and noticed, he did some post-install updates (flash/bootloader…).

The question is: when I put the sdcard with JP4.5 in an jetson device, which was not updated before (in extreme a old rev A.02 board) - is it working out of the box or do I have to prepare the hardware by manually executing any scripts? Or does he do this on first boot?

Thank you!

The sdcard image shall flash the qspi in your first boot up configuration.

If you are worried about something might missing, you could also just flash the board with sdkmanager.
