Update Beaglebone firmware & kernel

Note: This process can leave your Beaglebone unable to boot if you run out of space in the / partition. If your Beaglebone is working, leave it alone. Only do this for a Beaglebone where you don’t mind if it takes you a while to fix if something goes wrong.

Update Beaglebone kernel and firmware

  1. Ensure at least 100 MB free / disk space via
   df -h
   
  1. on the Beaglebone
   cd /opt/scripts/tools
   
   git pull
   
   ./update_kernel.sh
   
  1. reboot Beaglebone

Reinstall Linux

If the Beaglebone is messed up, you may need to reinstall Linux from scratch–erasing all existing files in the process.
