HATs and other add-ons • Re: Confusion about EEPROM and HAT

So, I have a M.2 NVME HAT and there's a lot of confusing information out there. Do HATs have EEPROM separate from RPi's? Do I need to update the HAT's EEPROM separately from the RPi's EEPROM? If so, how?

I ran this command and it found an update, but does it cover the HAT? TTyp there is no need for updating the HAT EEPROM (nless you're the manufacturer, releasing updates).

Code:

rpi-eeprom-update -a

Details on the boot EEPROM - the one on the Pi which gets accessed by the command above - can be found here https://www.raspberrypi.com/documentati ... oot-eeprom
