Awesome
This repo is now deprecated
Development is continuing at https://github.com/raspberrypi/rpi-update The rpi-update script will switch automatically to the new repo.
rpi-update
A tool to get the latest bleeding-edge firmware and kernel for your Raspberry Pi.
Notes
This is only intended for use with Raspberry Pi OS. If you are using a different distribution then check with the maintainers if using rpi-update is safe.
If the distribution ships a custom kernel (e.g. BerryBoot), then it almost certainly is not safe. Also differences in the usage of /boot and /opt/vc directories will likely make it unsafe.
Even on Raspberry Pi OS you should only use this with a good reason.
This gets you the latest bleeding edge kernel/firmware. There is always the possibility of regressions.
Bug fixes and improvements will eventually make their way into new Raspberry Pi OS releases and apt-get when they are considered sufficiently well tested.
A good reason for using this would be if you like to help with the testing effort, and are happy to risk breakages and submit bug reports. These testers are welcome.
Also if you are suffering from a bug in current firmware (perhaps as one of the reporters of the bug on github or forum) and a fix has been pushed out for testing, then using rpi-update is the right way to get the fix until it makes its way into new Raspberry Pi OS images and apt-get.
Backing up before updating is always advisable.
Installing
Installing under Raspberry Pi OS
To install the tool, run the following command:
sudo apt-get install rpi-update
Installing under other OSes
To install the tool, run the following command:
sudo curl -L --output /usr/bin/rpi-update https://raw.githubusercontent.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.
SKIP_VCLIBS
sudo SKIP_VCLIBS=1 rpi-update
Will update everything except the VideoCore libraries. Use this option to keep the existing VideoCore libraries if you do not want your local versions overwritten.
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.
FW_SUBDIR
sudo FW_SUBDIR=safe rpi-update
Allows the firmware to be installed to a subdirectory of /boot. This feature is
intended to support the os_prefix
setting that can be used in config.txt
.
By default, FW_SUBDIR is initialised to the value of os_prefix
in effect when
the device was booted, so as to overwrite the "running" firmware. To explicitly
install with no subdirectory (to install into /boot), use FW_SUBDIR=/
.
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.
PRUNE_MODULES
Allows you to delete unused module directories when doing an update. Set it equal to a non-zero value and it will remove all modules except the latest installed:
sudo PRUNE_MODULES=1 rpi-update
will remove previously installed module files. Use this option to free disk space used by older module updates.
JUST_CHECK
To just get a list of commits contained in rpi-update since you last updated, run:
sudo JUST_CHECK=1 rpi-update
This won't update your firmware
GITHUB_API_TOKEN
By default, rpi-update
will not use a custom GitHub API token. If you run into rate limiting issues, you can supply an API token on the command line:
sudo GITHUB_API_TOKEN=<your API token> rpi-update
RPI_REBOOT
To reboot after successfully update, run:
sudo RPI_REBOOT=1 rpi-update
You can use it to automate updates.
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
Pi-hole and similar DNS based may stop this tool from working. Make sure github.com domains are not blocked. (e.g. codeload.github.com)
