This small utility consists of two programs running on STM32F7[6|7]x used to switch between single mode and dual-mode flash.
- openocd
- arm-none-eabi toolchain
Type make.
The make command will generate two binaries:
- single-bank.bin
- dualbank.bin
Switching mode is done by executing either firmware from the target RAM, using openocd.
Automatic openocd scripts can be executed using
make single
or
make dualbank
to set the flash configuration to single or dual-bank respectively.
Type make check. The output will show either

or
Info : Dual Bank 2048 kiB STM32F76x/77x found
