STM32F7 Series Flash memory dual bank mode, software expansion for STM32Cube (AN4826)

The X-CUBE-DBANK-F7 firmware is intended to describe the STM32F7 Flash-memory dual-bank capabilities.

This firmware package is provided with three embedded software examples that cover the read while write (RWW), the dual boot and the device’s performance and consumption with Flash-memory in dual-bank mode.

This package complements the STM32CubeF7 firmware Flash-memory examples and gives more details about the dual-bank mode.

The X-CUBE-DBANK-F7 firmware is developed with STM32Cube embedded software. It uses the IAR Embedded Workbench®for ARM®(EWARM) by IAR systems®, the Microcontroller Development Kit for ARM®(MDK-ARM) by Keil®and the SW4STM32 tool chains and can be easily tailored for any another tool chain.

For more details refer to the application note AN4826.
