I have STM32CubeProgrammer v2.13.0 and I want to enable dual-bank flash memory on my F7 microcontroller (which supports this configuration) via the option bytes.

However, there is no such option byte available to enable dual-bank mode.

How should I enable dual-bank mode if the option byte isn't available?

Hello @McFlyz ,

Could you please precise the STM32F7 product you are using?

The dual bank mode is supported in STM32F76xxx and STM32F77xxx MCUs.

And the Flash memory read operations with two data width modes supported:

– Single bank mode nDBANK=1: read access of 256 bits

– Dual bank mode nDBANK=0: read access of 128 bits

And this options bytes is available in STM32CubeProgrammer.

Please refer to the reference manual of your MCU and precisely Embedded Flash memory (FLASH) section and check if the dual bank mode is supported in your MCU.
