Expected Behavior or Design

After a system update the system needs to be supervised if the update was successful:

  • Is the remote is able to boot the updated system?
  • Does the new app start successfully?

If the update doesn't work, the system needs to be automatically revert to the previous state.

Possible Solution

  • U-Boot boot counter
  • Successful boot flag in U-Boot environment, set by the remote app or a watchdog

Detailed Description and Additional Information
