Restoration from a microSD card backup returns the controller to the initial state when the system made the backup. Provided that the target controller is the same model, you may restore to a controller other than the one on which the backup was made. The restore procedure does not require access to Workbench. Launch the System Shell and use the shell menu to initiate a back up the data to the microSD card from the controller's Embedded MultiMediaCard (eMMC), where it is stored.

  • Prerequisites: You have a MicroSD card with a backup.
  1. Connect your PC to the Debug serial port using a USB-C cable.
  1. Log in to System Shell menu.
  • The Restore Menu opens. If more than one backup exists, the Restore Menu lists the files. Restore Menu 1. backup-20230502141937-v1 Select Backup file for Restore from list (Eg: 1) : 1 Selected backup file for restore: backup-20230502141937-v1
  1. Select the backup files to restore from the list and press Enter.
  • The System Shell displays the file to restore and prompts with:

Is backup passphrase same as the system passphrase [Y/N]? n Enter the passphrase used to encrypt the backup:

Confirm Passphrase

  • Confirm passphrase by either: (a) Entering ‘Y’ if the backup passphrase is the same as the system passphrase OR (b) Entering ‘N’ if the backup passphrase is not the same as the system passphrase.
  • The restore operation resets the controller to its factory state, then restores the backup. Restore operation will take several minutes and performs a few reboots when required. Restore operation will initiate after reboot Waiting for device to reboot
