Inquiry Regarding STM32F407G-DISC1 Target Support for Simultaneous Reading and Writing

[ahmedabdelrahman]

I am reaching out regarding a query about the STM32F407G-DISC1 target. Upon reviewing the datasheet, I noted that it indicates the target does not support reading while writing. However, upon personal experimentation, I found that it functions correctly in this regard.

Could you kindly provide clarification on this matter? I am curious to understand why my observations differ from the information provided in the datasheet.

Thank you for your attention to this matter. I look forward to your response.

Hello,

Are you talking about the Reading while Write to the Flash memory?

Ok but you need to provide more details about this statement ..

I am currently working on implementing a full Firmware Over-The-Air (FOTA) project on the STM32F407G-DISC1 target. As part of this project, I am considering dividing the flash memory into two banks.

My primary query pertains to whether the STM32F407G-DISC1 supports executing code from bank1  while writing to another bank2

STM32F407 does not support dual bank feature while for example STM32F42xxx and STM32F43xxx do.
