imx6sl PWM_backlight

[narutos]

Dear all:

I ran into a problem where PWM_backlight suddenly did not output while imx6sl was running, but I restarted the application and it returned to normal. Why?

Is there any log? Does this issue only exist in your application? Can you test other application?

No logs, no other applications tested, but I think I've solved it, it should be into system hibernation
