With a B-L072Z-LRWAN1 discovery board. After a stop mode wake up using the RTC, I go back to the while(1) loop of the main fonction. But I'm blocked at the end of the loop. Do someone knows why ?

 I'm sure that I don't go out of the loop cause I ask a led to blink if I exit the loop.

Here are my fonctions to enter and exit the stop mode.

void stm32l_lowPowerSetup(void)

{

HW_RTC_SetAlarm( 5000 );//5sec

__HAL_RCC_PWR_CLK_ENABLE(); // Enable Power Control clock

HAL_PWREx_EnableUltraLowPower(); // Ultra low power mode

HAL_PWREx_EnableFastWakeUp(); // Fast wake-up for ultra low power mode

// Disable Unused Gpios

_stm32l_disableGpios();

// Switch to STOPMode

HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);

}

void stm32l_lowPowerResume(void)

{

 /* MCU Configuration--------------------------------------------------------*/

 /* Reset of all peripherals, Initializes the Flash interface and the Systick. */

 HAL_Init();

 /* Configure the system clock */

   SystemClock_Config();

   DBG_Init( );

   HW_Init( );

 /* Initialize all configured peripherals */

   MX_GPIO_Init();

   MX_RTC_Init();

   MX_SPI1_Init();

   MX_USART2_UART_Init();

   MX_I2C1_Init();

   MX_ADC_Init();

HAL_I2C_MspInit(&hi2c1);
