Hi,

I'm having problem with stopmode.

I want to wake up uC with RTC Alarm in EXTI17.

But when i use stopmode with statement PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI), it didn't wait to RTC Alarm Event, it jumped in next to statements immediately.

I'm using debug mode with Jtag.

Could you help me to resolve that !

Thank you so much !a

What other interrupts do you have running? SysTick? WFI doesn't care where the interrupt came from.

Hi Clivel,

Thank you for your support.

I fixed it. My wake up pin has another interrupt.

Thank you so much !
