How to disable stm32g491 dual-bank mode

[TDock.1]

We were running tests originally with the g474re eval board to test/integrate SBSFU functionality. We needed to disable dual-bank mode with the STM32CubeProgrammer before being able to transfer via Ymodem.

We are now trying on the g491 and are failing this check:

if (SFU_LL_SECU_CheckFlashConfiguration(psFlashOptionBytes) == SFU_SUCCESS)

The STM32CubeProgrammer doesn't have the dual bank option for the g491. I'm probably missing something obvious but how can we change dual-bank mode outside of the option bytes page in the programmer? Or is it that it should be enabled and the problem lies in another configuration?

I do have the BFB2 unchecked.

Hello,

I think that G491 is not a dual-bank chip. The DBANK option in STM32CubeProgrammer has been removed since v2.8.0.
