Hello!I have a question about doing flash operations without the BLE wireless stack firmware being present in STM32. As it seems from the examples, the flash operations requires to notify the CPU2. For example, when doing flash erase, the CPU2 will h...

Hello!I am facing a problem when trying to erase a page from flash. It is working when the stm32wb5x_BLE_Stack_full_fw wireless stack is present. But since BLE is not used anymore, it has been removed, so now there is no wireless stack present. The p...

@Lubos KOUDELKAThe data is padded to 64bits. And thank You for the answer about the PWR_CR1_DBP bit. But is it normal that after running the lineHAL_PWR_EnableBkUpAccess(); // Which runs this line SET_BIT(PWR->CR1, PWR_CR1_DBP);the CFGBSY bit is set ...

@Lubos KOUDELKA Any ideas about why is this happening (regarding my previous reply)?

Yes, you are right, the CFGBSY is already set to 1 even before starting to lock the flash. And trying to clear the flag before even trying to do anything related to flash is not successful, the bit is not cleared (set to 0).While debugging in the FLA...

I added three pictures of the flash registers:firmware_flash_reg_after_flash_lock - Flash register after locking flash (breakpoint in hard fault).firmware_flash_reg_after_flash_unlock - Flash register after unlocking the flash (LOCK bit in CR turned ...

@Lubos KOUDELKANo, I am not running just the FLASH_EraseProgram, we have our own firmware where I am using the code form the FLASH_EraseProgram. There is no stack installed and everything related to CPU2 and the semaphore blocking has been left out. ...
