How to turn off the system's watchdog in stm32mp257

bugman
Associate III

hello ST:

     I used the stm32mp257 platform for KGDB debugging and found that it always resets the watchdog.

     I tried to disalbe the relevant nodes in the device tree of the kernel and optee:

      

///kernel:
&arm_wdt {
	/*timeout-sec = <32>;
	status = "okay";*/
	status = "disabled";
};

//Optee:
&iwdg1 {
/*timeout-sec = <32>;
	status = "okay";*/
	status = "disabled";
};

Will it still cause the system to restart after a period of time? How should this be handled?
