Hi Robert, Why don't you use the omnibusf4 board as starting point, since it uses same MCU model:
arm/stm32/omnibusf4/configs/nsh/defconfig:CONFIG_ARCH_CHIP_STM32F405RG=y Starting with a board and changing the MCU to other like you are doing will cause many issues, like this CONFIG_MM_REGIONS. It is better to start with a board using same MCU as your and then you evolve it to a different animal. Normally I test the board more similar to mine and then I create a new board from it, copying the entire board directory to a new name changing the boards/Kconfig in three places to add my new board and rename all CONFIG_BOARD_BLABLABLANAME to my board name.
