Hi,
I checked watch dog behavior by unit_test/wdt_driver_test.out.
Watch dog reset output WDOG1_WDOG_ANY on LCD_RESET ALT4 in i.MX6UL EVK.
I modified one thing, C738 was removed not to shut down DCDC_3V3, because customer don't want to power down the hole system.
At the first boot, WDOG1_WDOG_ANY is high after Linux boot, then I entered wdog test command that is unit_test/wdt_driver_test.out 1 1 1 and system shut off and reboot.
After it reboot, WDOG1_WDOG_ANY doesn't become high.
I confirmed that LCD_RESET pad set to ALT4 WDOG1_WDOG_ANY, but pin level is low.
How can I set WDOG1_WDOG_ANY to high?

Hello,
The WDOG output pin will reset after POR, the internal WDOG reset does not affect it.
