STM32WB5MM ble freertos project - Issue with CPU2 initializzation

[GPomp.1]

Hi support, 

I'm working with STM32WB5MM, the application is a ble application with freertos. 

I have this issue, sometimes at the boot the MX_APPE_Init() fails. In the details, the fuction APP_BLE_Init( void ) isn't executed because the function APPE_SysUserEvtRx() is never called. 

I try without success to:

1) Increase the minimun stack size (setting to 0x1000) and minimum heap size (setting to 0x400)

2) Increase the priority of the following interrupt: IPCC RX, IPCC TX

I attach the code of the main function:

int main(void)

{

 /* USER CODE BEGIN 1 */

  /**

  * The OPTVERR flag is wrongly set at power on

  * It shall be cleared before using any HAL_FLASH_***() api

  */

 __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_OPTVERR);

 /* USER CODE END 1 */

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

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

 HAL_Init();

 /* Config code for STM32_WPAN (HSE Tuning must be done before system clock configuration) */

 MX_APPE_Config();

}

What should be the issue? Can you give me any suggestion for try to solve this problem?

Hello Giampietro,

Have you found a solution to this issue? I'm noticing a similar issue that APPE_SysUserEvtRx() isn't called. I do notice that it sometimes works depending on my compiler optimization settings, but its seems very non-deterministic.

FreeRTOS appears to initialize just fine, but the APPE_SysUserEvtRx callback does not trigger.

Best,

Patrick
