Hello

There are WDT0～3(1st expiration～4th expiration)
1st：IRQ
2st：FIQ
3st：CPUx nRSET/COP_nRESET
4st：SYS_nRESET
(*Reference：Tegra_X1_TRM_DP07225001_v1.2p. P217. 8.6 Watchdog Timer Programming Guide)

I want to use a watchdog timer(4th expiration=SYS_nRESET)
I tried set only register(TIMER_WDT_CONFIG_0) SystemResetEnable.
But it does not work,if only SystemResetEnable.
Do I have to all register Enable？（Pmc2CarResetEN & SystemResetEnable & FIQ & IRQ)

Is it OK to understand that it is necessary to enable all WDT registers when using a system reset?

that’s all.

COSMICS,

Sorry that I didn’t get your purpose here. Could you elaborate more about what usecase you want to program on WDT?

@COSMICS
For your problem the system reset by WDT but can’t reboot successfully or WDT didn’t active to reset the system.
