Hi,
The AP (A53/A73) complex in the iMX8QM Ref manual (Rev F) has no mention of WDOG timer.
What is the mechanism to reconfigure/disable/enable/reset the WDOG for the AP complex ?
Is there any example for A53/A72 cores I can reference ? Is the SCU WDOG to be used (is SCU WDOG re-configurable?) ?
Thanks.

Hi rkohli2000
in latest linux wdog driver it is possible to reset A partition (AP complex ), with
arm_smccc_smc(IMX_SIP_TIMER, IMX_SIP_TIMER_SET_WDOG_ACT, SC_TIMER_WDOG_ACTION_PARTITION, 0, 0, 0, 0, 0, &res);
In previous releases with arm_smccc_smc(FSL_SIP_SRTC, FSL_SIP_SRTC_START_WDOG, 0, 0, 0, 0, 0, 0,&res); PMIC WDI was used :
Partition concept is described on
Wdog APIs are described in SCFW Porting Kit
Best regards
