Looking for the best ways upgrading from a nRF5 SDK / SoftDevice based design to Zephyr.
in my case, the nordic bootloader / upgrade process is configured for UART.
It would make most sense to let the bootloader stay and only wipe the SD + application area, replacing this with the zephyros based app.
i.e nice not having to rewrite the bootloader area (to mcuboot) to avoid potential bricks.
Anyone successfully done this?
