Cannot successfully build mcuboot on ncs 2.7.0

Hello,

I am terribly sorry for the late reply. I was pulled out of DevZone for a couple of weeks, but I am back now.

Interesting. Adding that snippet to the peripheral_uart sample's Kconfig file seems to work just fine. So I guess it is some other part not being included properly.

Do you have these in your main.c?

#include <zephyr/types.h>
#include <zephyr/kernel.h>

If that is not the issue, can you please zip the application you are working on, so that I can have a look? There may be another config being set in the peripheral_uart application that is not set in your application.

Best regards,

Edvin

Hi Edvin ,

I'm not sure if I understand the question. I'm just trying to add the mcuboot servirce to my firmware as I successfuly did with ncs 2.4.0.

I have my own kconfig definition:

    config BOOTLOADER
        bool "Enable OTA and dependencies"
        select FLASH
        select BT
        select BT_PERIPHERAL
        select NCS_SAMPLE_MCUMGR_BT_OTA_DFU
        select MCUMGR
        select MCUMGR_TRANSPORT_BT
        imply MCUMGR_TRANSPORT_UART
        select MCUMGR_GRP_IMG
        select BOOTLOADER_MCUBOOT
        select MCUMGR_TRANSPORT_BT_REASSEMBLY
        select MCUMGR_GRP_OS_MCUMGR_PARAMS
    endmenu

Then in my prj.conf I set:

CONFIG_BOOTLOADER=y

When I build the project with this setup and ncs 2.4.0 the MCUboot image is created. But with NCS.2.7.0 the build fails with this error:

phyr-eabi/bin/ld.bfd.exe: modules/nrf/drivers/mpsl/flash_sync/lib..__nrf__drivers__mpsl__flash_sync.a(flash_sync_mpsl.c.obj): in function `k_sem_reset': F:/ncs/htrace-firmwares/firmware-bt840/CB2/mcuboot/zephyr/include/generated/syscalls/kernel.h:1137: undefined reference to `z_impl_k_sem_reset'

I've been following other related post on the devzone, where some fixed the error using:

`CONFIG_LOG_MODE_MINIMAL=y`,

but it doesnt work.

The, I tried adding

CONFIG_MULTITHREADING=y

Then I'm able to build the mcuboot image, but the image size is too big.

Hello,

Are you trying to add the MPSL into the bootloader? Or do I misunderstand something here?

Best regards,

Edvin
