uConsole EEPROM Updater

A simple, zero-input script to automate updating the EEPROM of Raspberry Pi CM4 and CM5. Built specifically for the uConsole community.

Requirements

You must have git installed and the uConsole must be connected to the internet.

Usage

Run the following commands to download and execute the script:

wget https://raw.githubusercontent.com/NeilInnes/uconsole_eeprom_updater/refs/heads/master/uconsole_eeprom_updater.sh && bash uconsole_eeprom_updater.sh

After a reboot the devices EEPROM will be updated. You can confirm by running:

sudo rpi-eeprom-update

What it does

1. Detects your compute module type (Pi 4 or Pi 5).
2. Clones the official raspberrypi/rpi-eeprom repository to /tmp/.
3. Copies the latest firmware binaries to your local bootloader path without overwriting any existing files unnecessarily.
4. On CM4: Triggers a standard update via sudo rpi-eeprom-update -a.
5. On CM5: Backs up your current EEPROM config and applies the CM5-specific boot config to address SD card and power-off quirks.
6. Cleans up any temporary files the script created.
