Trying to use CONFIG_MCUBOOT_ACTION_HOOKS with MCUBOOT

[simon884]

Hi,

I'm trying to CONFIG_MCUBOOT_ACTION_HOOKS with mcuboot on a custom board build with an nRF9151. McuBoot works well, but I'd like to use CONFIG_MCUBOOT_ACTION_HOOKS to inform user for example with an led, process is running.

here is what I've tried without success:

in mcuboot.conf add CONFIG_MCUBOOT_ACTION_HOOKS=y

in child_image/mcuboot folder I've added mcuboot_hook.c

and in my Cmakelists.txt in my porject I added

if(CONFIG_MCUBOOT)
    zephyr_library()    
    zephyr_library_sources(mcuboot_hook.c)
endif()

But I always add an error during build with /opt/nordic/ncs/v2.5.0/bootloader/mcuboot/boot/bootutil/src/loader.c:2368: undefined reference to `mcuboot_status_change'

It's look like I've missed something somewhere...

Thanks

Hi Simon,

I would recommend that you first check that the file is indeed included.

1. Add #warning "Source file inclusion verified" to the mcuboot_hook.c.

2. Add message("CMake check runs for MCUBoot -----------------------------------------") to the CMake check

Ok, so to resolve my issue, I have to move my hook c file et CMakeList to my custom board directory....

Is that a question, or an explanation on how you fixed your error?

hi,

it's an explanation. To resolve the issue I have to:

- move my hook file in /custom_board_dir/boards/arm/my_board

- add CmakeLIste in the same dir

So it is the only one solution to do thaht ? Is it possible to add hook file and Cmakelist in my app project instead ?

I think the alternative would be to make a workspace application and include the hook for that.

There are no way to add source code for child images as far as I know, so you can not add it as part of the application, no.
