FRASTM · FRASTM · commit b6730706adb9 · 2025-07-23T17:22:42.000+02:00
Define the stm32 disco board variant configuration to set
the STM32 XIP mode that will enable the MemoryMapped mode.
See Kconfig of the stm32 soc. Choose the mcu_boot partition
where to build ../bootloader/mcuboot/boot/zephyr
The zephyr, chosen zephyr,flash = &amp;flash0; is in the board dts.
The zephyr,code-partition = &amp;boot_partition; is given by the app.overlay
