An easier way to update the firmware of your Odroid-XU4.
To install the tool, run the following command:
sudo curl -L --output /usr/bin/xu4-update https://raw.githubusercontent.com/c0d3z3r0/xu4-update/master/xu4-update && sudo chmod +x /usr/bin/xu4-update
Then, to update your firmware, just run the following command:
sudo xu4-update
After the firmware has been sucessfully updated, you'll need to reboot to load the new firmware.
To upgrade/downgrade to a specific firmware revision, specify its Git hash (from the https://github.com/c0d3z3r0/odroid-xu4 repository) as follows:
sudo xu4-update fab7796df0cf29f9563b507a59ce5b17d93e0390
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.
By default, xu4-update
will attempt to update itself each time it is run.
You can disable this behavior by:
sudo UPDATE_SELF=0 xu4-update
sudo SKIP_BACKUP=1 xu4-update
Avoids making backup of /boot and /lib/modules on first run.
sudo SKIP_REPODELETE=1 xu4-update
By default the downloaded files (/root/.xu4-firmware) are deleted at end of update. Use this option to keep the files.
sudo ROOT_PATH=/media/root BOOT_PATH=/media/boot xu4-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.
By default, clones the firmware files from the master branch, else uses the files from the specified branch, eg:
sudo BRANCH=next xu4-update
will use the 'next' branch.
There are two possible problems related to SSL certificates that may prevent this tool from working.
-
The time may be set incorrectly on your XU4, which you can fix by setting the time using NTP.
sudo aptitude 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 aptitude install ca-certificates
