    Hi @guillaumemarce

    We will be soon releasing a new BIOS with iTCO watchdog enabled by default that will make sure the board won't get stuck and it will reboot in case it freezes.

    About the freeze, I can see that you are using ubilinux with 4.9 kernel. I would suggest you to move to a newer release of our Linux systems (either Ubuntu or Yocto) which provides much newer kernel and see if the issue is still happening there.

    Yes it does, iTCO was enabled between version 4.1 and 4.4, but never released (you can see from the history file), 4.6 is the latest and only released version after R4.0.
