Raspberry Pi 4 or Pi 5 EEPROM Update

Step-by-step Raspberry Pi EEPROM Update instructions

These procedures apply to Raspberry Pi 4 or Pi 5 with Raspberry Pi OS (64-Bit), (32-Bit), (Legacy 64-Bit) or (Legacy 32-Bit).

General Notes

1. General: The procedures below are optimized for updating Raspberry Pi 4 or Pi 5 EEPROMs with Raspberry Pi OS (64-Bit), (32-Bit), (Legacy 64-Bit) or (Legacy 32-Bit).

2. Internet access during setup: Many of the steps below assume and require the Raspberry Pi is connected to a network with access to the Internet.

Notice about updates, upgrades and installations failing due to repository or network congestion or outages

Occasionally updates, upgrades and installations fail due to repository or network congestion or outages. Sometimes there is an appropriate message saying as such, sometimes a missing file is reported, and sometimes there is just a failure message without an explanation. When this occurs, simply run the command again. If that does not solve the issues immediately, try again later.

- or -

Via a Display, Keyboard and Mouse

- or -

Via SSH

Connect using the IP address or URL of the Raspberry Pi

Determine the Raspberry Pi IP Address:

Via Raspberry Pi Connect Remote shell or Raspberry Pi Connect Screen sharing, then open a Terminal window

https://www.raspberrypi.com/software/connect

sudo hostname -I

Connect directly to the Raspberry Pi via a Display, Keyboard and Mouse, then open a Terminal window

sudo hostname -I

Use an IP Scanner tool such as Advanced IP Scanner on a PC or alike to locate the IP Address assigned to the Raspberry Pi

Note:

Update Raspberry Pi software documentation: https://www.raspberrypi.com/documentation/computers/os.html#update-software

Download the latest package lists

sudo apt update -y

Download and install the updated packages listed in the package lists

sudo apt full-upgrade -y

Update the Raspberry Pi 4 or Pi 5 EEPROM Image Version

Notes:

This tool only works with Raspberry Pi 4 or Pi 5. Raspberry Pi 3B+ and below have a ROM that can not be updated.

Update Raspberry Pi bootloader documentation: https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#update-the-bootloader-configuration

Check for a newer Raspberry Pi 4 or Pi 5 EEPROM image version and if found download and apply it

sudo rpi-eeprom-update -a

Select the latest Bootloader Version

Remove packages that automatically installed and are no longer required

Occasionally excess update, upgrade and installation packages install automatically, but are no longer required. These can be removed automatically.
