Hi,
I am using custom board based on SaberSD design (processor imx6dl).
Using Watchdog_1 for timeout and reset, IPU1_DISP0_DATA08 / IPU2_DISP0_DATA08 / PWM1_OUT / WDOG1_B / <GPIO4_IO29> in is connected to PMIC reset pin.
If SRS bit is cleared / watchdog time out happens OS get restarted, but WATCHDOG1_B is not asserted( so no power reset happens).
WCR is initialized to 0x779f.
Thanks and regards,
Arun

Hi all,
Issue is resolved
Reason for Issue:
Configured the MUx control of DISP0_DATA08 to WDOG1_B, but doesn't configured pad control registers.
WCR= 0x779F;
In above initialization WDA bit is cleared.
So WDOG1_B pin get asserted, once I Configured DISP0_DATA08 PAD and MUX control registers.
Fix:
Configure DISP0_DATA08 PAD and MUX control registers.
Set WDA bit to 1, so it behaves in system default mode.
WCR = 0x77BF;
After above fix WDOG1_B pin gets asserted whenever watch dog timeout happens or SRS bit is cleared.
