How to trigger watchdog

Thanx for the detailed info, which seems to implement the required functionality. Unfortunately, after consultation of ZBT, they informed me, that this connection does not exist on the WE1026.

Hi All,
very intersting loop.
I'm working on the same thinks on OpenWrt 18.06 on Microchip SAMA5D31.
My enviroment is composed by at91bootstrap (primary BL), u-boot (second BL) and than DTB,Kernel and RootFS
In order to grant board rese in case of at91boot or uboot stop i've enable at91boot watchdog .

Unfortunatly in this way OpenWrt restart near console activation request due to previous watchdog trigger by at91boot.

Could you suggest something in order to grant reset in at91boot or uboot stop and oviously grant to compleate the normal boot ?
Thanks
Best
Fabio
