Dear all i want to wakeup stm32l4 in every two minute from stop2 mode using RTC,give me suggestion.I am using example code from st and trying  PWR_STOP2_RTC on my custom board,i am finding that l4 is not going in stop2 because the LED2 in example is always toggling.

    Please:

    1. FIX THE CAPS LOCK ON YOUR KEYBOARD!
    2. Don't put the whole question in the message title!

    Rather than wait for next time, why not fix it now?
