An easier way to update the firmware of your Raspberry Pi
To install the tool, run the following command as root:
wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && chmod +x /usr/bin/rpi-update
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:
sudo apt-get install ca-certificates
To then update your firmware, simply run the following command as root:
By default, the 224MB memory split will be used. If you'd like to use the 192MB split, then type:
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.
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.
