Set the WD_WINDOW register WD_WINDOW_3:0 as '1010' , But it is still reset, is there any other setting to make it work normally. It is normal if you use defult setting to 512 ms

why does it reset after your set this register?

[guoweisun]

You can set the WD_WINDOW register WD_WINDOW_3:0 as '1010' to get the 32ms refresh time.

Watchdog timer, set to refresh the WD in 3/4 of the period (open window). It means that the MCU is reset by the SBC .
