Trying to get custom STM32WB55 board to advertising state.

[Louis Loving]

I am using STM32Cube FW_WB V1.1.1 and built a new project.

I have programmed stm32wb5x_BLE_Stack_fw.bin into the memory space for CPU2 (0x80CB000).

I have added the following interrupt handlers:

void IPCC_C1_TX_IRQHandler(void)
{
  HW_IPCC_Tx_Handler();
 
  return;
}
 
void IPCC_C1_RX_IRQHandler(void)
{
  HW_IPCC_Rx_Handler();
  return;
}

I have configured STM32_WPAN as follows:

My small application runs fine but I get no indication that the BLE is running at all. I am using ST BLE Sensor to scan but do not see my device.

Any pointers on where to look or what to check would be greatly appreciated.

After further review, the problem was not with #pragma pack(1) per se. The #pragma pack directive "affects declarations of structures following the pragma directive to the next #pragma pack or the end of the compilation unit. Once the structures that I wanted packed were covered", I added the #pragma pack() with an empty list. This "restores the structure alignment to default" and the hard fault went away.
