rpi-update

An easier way to update the firmware of your Raspberry Pi.

Installing under Raspbian

To install the tool, run the following command:

sudo apt-get install rpi-update

Installing

To install the tool, run the following command:

sudo curl -L --output /usr/bin/rpi-update https://raw.github.com/Hexxeh/rpi-update/master/rpi-update && sudo chmod +x /usr/bin/rpi-update

Updating

Then, to update your firmware, just run the following command:

sudo rpi-update

Activating

After the firmware has been sucessfully updated, you'll need to reboot to load the new firmware.

Options

If you'd like to set a different GPU/ARM memory split, then define gpu_mem in /boot/config.txt.

To upgrade/downgrade to a specific firmware revision, specify its Git hash (from the https://github.com/Hexxeh/rpi-firmware repository) as follows:

sudo rpi-update fab7796df0cf29f9563b507a59ce5b17d93e0390

Expert options

There are a number of options for experts you might like to use. These are all environment variables you must set if you wish to use them.

UPDATE_SELF

By default, rpi-update will attempt to update itself each time it is run. You can disable this behavior by:

sudo UPDATE_SELF=0 rpi-update

SKIP_KERNEL

sudo SKIP_KERNEL=1 rpi-update

Will update everything except the kernel.img files and the kernel modules. Use with caution, some firmware updates might depend on a kernel update.

SKIP_BACKUP

sudo SKIP_BACKUP=1 rpi-update

Avoids making backup of /boot and /lib/modules on first run.

SKIP_REPODELETE

sudo SKIP_REPODELETE=1 rpi-update

By default the downloaded files (/root/.rpi-firmware) are deleted at end of update. Use this option to keep the files.

ROOT_PATH and BOOT_PATH

sudo ROOT_PATH=/media/root BOOT_PATH=/media/boot rpi-update

Allows you to perform an "offline" update, ie update firmware on an SD card you are not currently booted from. Useful for installing firmware/kernel to a non-RPI customised image. Be careful, you must specify both options or neither. Specifying only one will not work.

BRANCH

By default, clones the firmware files from the master branch, else uses the files from the specified branch, eg:

sudo BRANCH=next rpi-update

will use the 'next' branch.

Troubleshooting

There are two possible problems related to SSL certificates that may prevent this tool from working.

  • The time may be set incorrectly on your Raspberry Pi, which you can fix by setting the time using NTP.

    sudo apt-get install ntpdate
    sudo ntpdate -u ntp.ubuntu.com
    
  • The other possible issue is that you might not have the ca-certificates package installed, and so GitHub's SSL certificate isn't trusted. If you are on Debian, you can resolve this by typing:

    sudo apt-get install ca-certificates
