Errors with building a sample project with MCUboot

[imtiz_ahmed]

Hi,

I am following these steps to build a sample project to try out OTA updates of the firmware.

https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu

However the issue is that when I add CONFIG_BOOTLOADER_MCUBOOT, my builds start to fail. I tried with both 1.8.0 and 1.9.1 sdk

# Ensure an MCUboot-compatible binary is generated.

CONFIG_BOOTLOADER_MCUBOOT=y

The error I get is:

Any idea what am I might be doing wrong? 

Thanks!

Hi Ahmed, 
I tried here and has no problem with compiling. 
From the log it seem that the following is missing: 

Could you check if you can find Kconfig file in your NCS  at this folder: \nrf\modules\mcuboot\boot\zephyr ? 

If you don't I would suggest to re-install the SDK, I would suggest to do that using Toolchain Manager as instructed here.

Hi Hung,

The Kconfig file is available at given path.




I originally installed the SDK via nRF Desktop Connect->Toolchain Manager. However I will try to reinstall it again to see if that helps!

Thanks!

Hi, 
I can see that the folder you are looking at is for v1.8.0 when the complain in the log was about v1.91. Please double check.

Hi, 

good catch, I pasted the logs in the original post when I tried using 1.9.1 version of SDK as well. That too was failing. Yesterday I uninstalled all versions of SDK and installed 1.8.0 again. Unfortunately, I got same error. I might trying building from scratch on another machine.

Hi Imtiz, 

I don't have much experience with MACOS but can you compile normal application (non MCUBoot) ? 
Usually on my Windows machine before I can build I would need to run env.cmd in \toolchain\cmd to configure the PATH and the ZPHYR_BASE. It is done automatically if you use Visual Studio Code.
