STM32WB Get wireless stack version at runtime

Hello,

I'm using STM32Wb CubeMX HAL FW 1.10.1 and a PNUCLEO-WB55

I'd like to get the wireless coprocessor stack version at runtime. I didn't find a HAL API to do this, so I went about it manually using AN5185 as a guide. According to AN5185, the device information table contains (among other things) the wireless stack version. This table is in SRAM2a and should be accessible by both cores. Using the flowchart on page 16, I'm trying to read the magic number stored at the top of this table, but I'm always getting back 0x00000000. Here's my code:

void print_device_info(void)
{
  // Get IPCCDBA
  FLASH_OBProgramInitTypeDef pOBInit;
  HAL_FLASHEx_OBGetConfig(&pOBInit);
  volatile uint32_t *ipccdba = (uint32_t *)(pOBInit.IPCCdataBufAddr);
  // Get offset of device info table
  uint8_t device_info_table_offset = (uint8_t)*ipccdba;
 
  printf("Device info table magic number = %08lX\r\n", *(ipccdba + device_info_table_offset));
  
  __BKPT(0);
}

If I point the debugger at that memory address, it indeed reads 0.

Code is called after all MX init functions

/**
  * @brief  The application entry point.
  * @retval int
  */
int main(void)
{
  /* USER CODE BEGIN 1 */
 
  /* USER CODE END 1 */
 
  /* MCU Configuration--------------------------------------------------------*/
 
  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();
 
  /* USER CODE BEGIN Init */
  /* USER CODE END Init */
 
  /* Configure the system clock */
  SystemClock_Config();
 
  /* USER CODE BEGIN SysInit */
  printf("System init complete!\r\n");
  printf("MCU:%ld,%ld\tHAL version:%ld\r\n", HAL_GetDEVID(), HAL_GetREVID() ,HAL_GetHalVersion());
  printf("Initializing peripherals...\r\n");
  /* USER CODE END SysInit */
 
  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_USART1_UART_Init();
  MX_CRC_Init();
  MX_I2C1_Init();
  MX_RF_Init();
  MX_RTC_Init();
  /* USER CODE BEGIN 2 */
  printf("Initializng sensor...\r\n");
  sensor_init();
 
  printf("Initializing WPAN...\r\n");
  /* USER CODE END 2 */
 
  /* Init code for STM32_WPAN */
  APPE_Init();
  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  print_device_info();
  printf("Initializing complete!\r\n");
  while (1)
  {
    HAL_GPIO_TogglePin(LD3_GPIO_Port, LD3_Pin);
    /* USER CODE END WHILE */
 
    /* USER CODE BEGIN 3 */
    HAL_Delay(1000);
  }
  /* USER CODE END 3 */
}

Looks like everything is ok:

I must be missing something basic. Can wireless copro version be read at runtime? If so, how?

Thanks,

Andy
