When I Debug cmwx1zzabz_0xx, I get a hard fault somewhere near a call to HAL_PWR_EnterSLEEPMode(). It happens just after all the init code, somewhere in the first call to MX_LoRaWAN_Process(). If I step into MX_LoRaWAN_Process() and continue stepping, there is no fault.
Note that I commented out the calls to DBG_Disable() and DBG_ProbesInit() in SystemApp_Init() since they drop the ST-Link connection over USB.
