The documented watchdog is identicaly the same reading the user manual as the one used in the A64. After investigation it seems that on some SoC the first watchdog doesn't make the board reboot. Some tests has been performed and it seems that first H6 version aren't affected only the latest one. Chen-Yu Tsai's boards: Pine H64 - H6 V200-AWIN H6448BA 7782 =3D> OK OrangePi Lite 2 - H6 V200-AWIN H8068BA 61C2 =3D> KO Cl=C3=A9ment P=C3=A9ron's board: Beelink GS1 - H6 V200-AWIN H7309BA 6842 =3D> KO I think it could good to add it with a comment anyway. In case a user want to activate it and isn't aware of this issue. The r_watchdog is still available and usable on all the H6 boards.
