[liuyanfeng]

I want to use NRF9160 for development, now I want to pick something bootloader, so which one do I use

1.  \ zephyr, replication, bootloader, McUboot \ zephyr

 

2. \ zephyr, replication, bootloader, McUboot \ samples \ zephyr \ hello - world

 

3.  \ zephyr, replication, bootloader, McUboot/boot/zephyr

which one ?oen two three?

thank you very much!

The code of the MCUboot used with NCS/Zephyr resides in bootloader\mcuboot\boot\zephyr\(main.c). E.g. if you add CONFIG_BOOTLOADER_MCUBOOT=y to the prj.conf of your sample, this project will be used.

You don't need to build it separately by the way, it will get built automatically when setting CONFIG_BOOTLOADER_MCUBOOT=y as explained above. The MCUboot and application hex files will get merged into <application>build/zephyr/merged.hex.

Best regards,

Simon
