STM32WL5 2nd core reset

[DiegoKer]

Hi,

I'm using STM32WL5 SoC in my lora project.
I started from this example: "LoRaWAN_End_Node_DualCoreFreeRTOS".
In my board, I have a problem at startup, CPU2 doesn't start after a simple pin reset (NRST).
The only way is to switch power supply off, wait for all capacitors down, and switch on.
I tryed to clear PWR_CR4_C2BOOT at startup, without success.

This is where CPU1 wait forever:

void MBMUXIF_WaitCm0MbmuxIsInitialized(void)

{

while (pMb_RefTable->SynchronizeCpusAtBoot != CPUS_BOOT_SYNC_CPU2_INIT_COMPLETED)

{

}

}

Can anyone help me?

Thanks.

Hello @DiegoKer 

Arr you using the exact example "LoRaWAN_End_Node_DualCoreFreeRTOS" without any modification and following the readme procedure? If so, do you have the same issue will using the sequencer based example?
