Hi All,

I'm using the P-NUCLEO-WB55-Nucleo and I'm using all the two CPUs (CPU1 + CPU2). I must put the all board in the stop mode, I've downloaded the example PWR_EnterStopMode but I've some doubs about the manage of the CPU2 to entering in  stop mode. Do it exist some examples that shows how to manage all the CPU in order to enter in stop Mode?
