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?

Hello,

You can mark the image as "pending" with this function: https://github.com/nrfconnect/sdk-mcuboot/blob/148712e7b4618aadbedd04e8d3ce5c3847d3be4f/boot/bootutil/include/bootutil/bootutil_public.h#L205. 

Best regards,

Hello Berg,

thanx for help.I tried boot_set_pending(1),but still cannot makes it effect. I call This api in \ncs\v2.9.0\bootloader\mcuboot\boot\zephyr\main.c         int main()

is it right?

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.

[Martin Evans]

CONFIG_IMG_MANAGER=y is added as well

Did you try to call boot_set_pending()? 

[Martin Evans]

I try boot_set_pending now,it can pass the complie,but a warning happend.
warning: implicit declaration of function "boot_set_pending"

It must be that i am not include the head file,but once i do #include <bootutil/bootutil_public.h>,an ERROR(No such file....) wil happen.Any solution plz?

[Martin Evans]

Good new is that boot_set_pending return 0-success.

Bad new is that the new img is not take effect.

My primary slot makes led green,and Secondary turn it  into red. boot_set_pending(1) return 0,after reset it is still green.

[Vidar Berg]

I see the problem now with using the relative include path. You can include "#include <zephyr/dfu/mcuboot.h>" instead and call 

boot_request_upgrade(1); instead.

[Martin Evans]

But do this will makes anoter err happened just like what i have said
