Questions regarding : nRF Connect SDK Tutorial - Part 2

[Chris]

Hello,

I started following the tutorials in the devzone blog and was really helpful to understand the logic behind the ncs. I got stuck in some issues and would like some help please!

In part 2

2.1.2 User workflow - Application as the manifest repository

When running west update I get the following error

 

My project_hello is outside the ncs folder ofcourse! I tried to find this error but with no luck ! I attached the project to checkout it out, maybe I missed something

project_hello.zip

Thank you for your help in davance :)

I tested your project and was not able to recreate your issue. What's your west version and python version? I got the following:

<..>\project_hello\project_hello>west --version && python --version
West version: v0.6.3
Python 3.8.0

Best regards,

Simon

Thank you Simon for your reply. 

I reinstalled nRF connect SDK v1.2.0 using the new tool  "Toolchain Manager".

I removed the old sdk  and  gnuarmemb folders and paths before.

I started from scratch and now I'm in 2. Set up a project (before starting managing my projest with west). I am able to build the project using segger embedded studio but got errors using west build as shown below:

west build -b nrf9160_pca10090ns -d build_nrf9160_pca10090ns
-- west build: build configuration:
       source directory: D:\DEV\Phantomtracker\software\my_projects\project_hello\hello_world

       BOARD: nrf9160_pca10090ns (origin: command line)

ERROR: command exited with status 1: 'C:\Program Files\CMake\bin\cmake.EXE' '-BD:\DEV\Phantomtracker\software\my_projects\project_hello\hello_world\build_nrf9160_pca10090ns' '-SD:\DEV\Phantomtracker\software\my_projects\project_hello\hello_world' -GNinja -DBOARD=nrf9160_pca10090ns

I have the project forlder outside ncs, so I tried setting the following

set ZEPHYR_TOOLCHAIN_VARIANT="gnuarmemb"
set GNUARMEMB_TOOLCHAIN_PATH=D:\DEV\nRF\ncs\v1.2.0\toolchain\opt

but no luck.

I have 

West version: v0.6.3
Python 3.8.1

I prefer using the command line, it's much simpler.

any ideas why I'm having this errors !

Regars,

Hicham
