Hello,

 

I'm trying to wake a MKL17 from LLS on rtc sg if anyone here can be of help.

When I tryto wake a MKL17 from LLS on external pin, It is ok.

I'm setting bit 7 of the LLWU_ME to enable the RTC Sg as a wakeup module.

Hi Dalia Grimal

Are you able to share more information about your implementation? What is the source of the RTC? in some power modes the source clock could be powered off. Also, did you enable the RTC interruption? I would test the RTC functionality before enabling the power mode in the application.

For your reference:

Also, I recommend the SDK code examples.

Best regards
