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?

 

Best Regards,

Sugiyama
