hi Bjørn,

Thanks for the replay. we have changed our requirement slightly instead of storing two image in internal flash one we are storing in external flash. Basically my requirement is I need to program another mcu(stm32) using nrf51822 so stm32 image need to store in external flash so later will flash stm32 image using uart. For this I need to change bootloader a bit but I dont have much experience for writing bootloaders so im very confusing to change the bootloader could you please help me what and all change required to store stm32 image in external flash. Now im using dfu_dual_serial boatloader example as a starting point.
