To install the tool, run the following command as root: To install the tool, run the following command:

If you get errors relating to certificates, then the problem is likely due to one of two things. Either the time is set incorrectly on your Raspberry Pi, which you can fix by simply setting the time using NTP. 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're on Debian, you can resolve this by typing: If you get errors relating to certificates, then the problem is likely due to one of two things.

To upgrade/downgrade to a specific firmware revision, specify it's Git hash as follows:
By default, rpi-update will attempt to determine the split you're currently using, and then use that split. If it cannot determine what split you are using, it will default to 224MB.
If you'd like to explicitly select a split, simply provide the RAM split value after the command as follows:
<pre> <pre>
rpi-update 192 rpi-update <git hash>
</pre> </pre>
If you'd like to use the 128MB memory split, then the command is the same as the above, except with 128 instead of 192. If you'd like to set a different GPU/ARM memory split, then define gpu_mem in /boot/config.txt.
After the firmware has been sucessfully updated, you'll need to reboot to load the new firmware.
This tool is experimental, and may screw up your install. If you have problems with it, post an issue to this GitHub repo and I'll see if I can help you.
