STM32WB5MMG - CPU2 is Blocking Flash operations from CPU1

Hi everybody,

Here's a bit of context of my project:

  • I'm using BLE Mesh Template, using Sensor and Generic Models.
  • I'm enabling the USB and the CDC middleware. Thus:
  • I changed the configuration of the SystemClock.
  • The nodes are mostly self-provisioned.
  • One node is working as root/gateway.

And here comes the problem. When I try to Self-Provision the Root Node, by enabling the

DYNAMIC_PROVISIONER feature in mesh_cfg_usr.h, and execute the command ATEP ROOT. The app "hangs" indefinitely.
These two logs show: 1.- The uncomplete self-provisioning process and (2.-) the second log shows the complete self-provisioning process.
 
UNCOMPLETE PROCESS. Application Crashes; the last line is where the app dies.

Now, I take time to figue out what was causing this problem. And I found out this.

The app is hanging in this call stack:

AppliPrvnNvm_Process > AppliPrvnNvm_FlashProgram > PalNvmWrite > FD_WriteData > FD_WriteSingleData > 
ProcessSingleFlashOperation
 
There, the PC is on an infinity loop in the line:

 

while(LL_FLASH_IsActiveFlag_OperationSuspended());

 

 Take a look of this and:

 

/**
  * @brief  Check if new program or erase operation request from CPU1 or CPU2 is suspended
  * @rmtoll FLASH_SR      PESD         LL_FLASH_IsActiveFlag_OperationSuspended
  * @rmtoll FLASH_C2SR    PESD         LL_FLASH_IsActiveFlag_OperationSuspended
  * @retval State of bit (1 or 0).
  */
__STATIC_INLINE uint32_t LL_FLASH_IsActiveFlag_OperationSuspended(void)
{
  return ((READ_BIT(FLASH->SR, FLASH_SR_PESD) == (FLASH_SR_PESD)) ? 1UL : 0UL);
}

 

and effectively, this bit is set in the FLASH SR register.

Taking a look on the datasheet, this PESD bits in SR is set and cleared by Hardware.

 

How can I solve this, is there a problem in the BLE Stack firmware loaded in the CPU2?

Hey, it's been a while since I've been here.

Yeah, I've been working with the STM3232WB5MM-DK.
It is worth mentioning that is an aleatory situation, perhaps in 2 out of 5 attempts this problem occurs, and the only way out is with a hardware reset.
