how to make new image takes effect

[Martin Evans]

Hello,Nordic team

I am programming with nrf52833 and ncs v2.9.0

I am going to do dfu not by YOUR example(FOTA or UART……)

I flash_write() data to image-1 address，and what should i do to make image-1 take effect(take place of image-0) after reset?Need I config register or other ways?

Best regard

[Martin Evans]

What u mean is that i shold call boot_set_pending() in application after flash_write finished right?
But this file bootutil_publich.c and its head file are in \ncs\v2.9.0\bootloader\mcuboot\boot\bootutil\src,How to say...how i include its path?

[Vidar Berg]

Yes. The bootutil functions is included in the app by enabling CONFIG_MCUBOOT_IMG_MANAGER in your project configuration.

[Martin Evans]

Thanx, Ive added CONFIG_MCUBOOT_IMG_MANAGER=y in my prj.conf,but compile failed,report that boot_set_pending is undefined.

[Vidar Berg]

Did you include the "#include <bootutil/bootutil_public.h>" header in your source file as well?

[Martin Evans]

I added it but report err: No such file.

And i find this  link.I added 
CONFIG_MCUBOOT_IMG_MANAGER=y
CONFIG_MCUBOOT_BOOTUTIL_LIB=y

to my conf file, and #include <zephyr/dfu/mcuboot.h> .

But still report   undedined reference  boot_request_upgrade.
