I am implementing a dual-bank-like firmware architecture on the STM32WLE5CCU6 microcontroller, which does not natively support true dual-bank flash. In this setup, I need to write data to a region of the internal Flash memory that is part of the same memory space from which the code is currently executing. I would like to understand how Flash write operations can be safely performed in such a scenario—specifically, how to write to a different section of the same Flash memory while code execution continues from another region within that same Flash.
