Update Raspberry Pi on Yellow

I would like to update the firmware for the Raspberry Pi CM5 I have in my Home Assistant Yellow, and it seems it should have the command to do that in the image: operating-system/buildroot-external/configs/yellow_defconfig at a64767b123864b439777e8ca5600c597493528a9 · home-assistant/operating-system · GitHub

I access the system using the advanced terminal without the protection mode, but it seems the command doesn’t exist (in comparison docker command exists).

Because of the aforementioned line, shouldn’t the comand rpi-eeprom-update be available?

The rpi-eeprom-update tool is part of the host OS, not the Docker container, so it cannot be run from inside the container. You need shell access to the underlying OS to execute it.

Home Assistant OS debugging access is documented here:

Hmmm… So even using the Advanced SSH & Terminal add-on I’m still not accessing the host OS, even with the protection disabled?
