This method replaces the entire system image with a new firmware version. It is similar to reinstalling an operating system on a computer. Using this method erases all user data and customizations.
Unless you specifically need to reinstall the full firmware, Kerlink strongly recommends using APT for regular updates and maintenance.
To apply a firmware reinstallation, you need to:
/boot/upgrade/ directory (create it if necessary)sudo reboot upgradeTo apply a firmware downgrade to Keros 5, you need to use the specific magic link dedicated resources
The gateway will reboot and the downgrade may take few minutes.
Regarding downgrade to a previous Keros6 version, the system does not allow it.
If you need to make such an operation, you need to apply a firmware reinstallation to the wanted version.
The factory reset completely reinstalls the stock firmware from scratch. The stock firmware corresponds to the last installed firmware with the factory upgrade method.
To manually trigger a factory reset on your WirnetTM gateway, please follow these steps:
Perform the command sudo reboot factory-reset
The restore will reinstall the stock firmware but, unlike the factory reset, the gateway will keep and apply the last successful network configuration. This way the gateway should still be able to connect to online services after the restore.
An instability counter is used to detect system instability. If 16 consecutive reboots are detected due to a watchdog, a restore operation is triggered
The counter is reset if the system reboots without instability
Perform the command sudo reboot restore
