Secure by default: Secure boot

The controller supports the secure boot function. During the boot process, digital signatures are used to check whether the firmware has been compromised. Firmware that is detected as compromised is not loaded. In this case, the CSEC LED starts to light up permanently in blue or flash.

At the start of the boot process, the LED lights up briefly. This has no security-related meaning.

If the firmware has been compromised:

  • Reset the controller with reset type 2 and install the latest firmware.
