Can't flash erase on "Single bank mode" (STM32G4)

Hi!
I have no problem with writing, reading, or erasing with dual mode, but erase stops working as soon as I change the DBANK option byte to "Single bank mode" (Uncheck it).

I assume there is something i need to change in the STM32G4XX files as well, because DBANK is always defiend:

I have tried to search on my own, but have not found any solution. Out of the 2 relevant hits I found online, one did not work and the other seems to be unverified and not easy to test

This is my code, which simply calls "stm32g4xx_hal_flash.c" and "stm32g4xx_hal_flash_ex.c" functions

 

 

 

 

if(HAL_FLASH_Unlock() == HAL_OK)
{   
    uint32_t PageError;
    if(HAL_FLASHEx_Erase(&pEraseInit, &PageError) != HAL_OK)
    {
        HAL_FLASH_GetError();
    } 
    while(HAL_FLASH_Lock() != HAL_OK);
}

 

 

 

 

 Anyone have any suggestion?

Thank you in advance
