Build nrf project using Cmd

[shruti mishra]

Hi ,

I am working on nrf based project . I m trying to build my project using Cmd  . I followed the steps given in link -

https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/ncs-tutorial---temporary#h155sjwm56iy71nftthh5gikrw9b2thl

But when i trying to build project using cmd instead of bash with following command - C:\project_folder_path\v1.2.0\toolchain\opt\bin\Scripts\west.exe build -b nrf910

i encountered the following error - ModuleNotFoundError: No module named 'west'

i could not able to build my project . Will you please suggest the steps for building project in cmd . 

Best Regards,

Hi.

Based on the path you used, I assume you installed NCS using the Toolchain Manager?

Did you open CMD from the Toolchain Manager?

If you did, it should work without any problems, and you should not need to provide the full path to the executible, 'west build -b <board name>' should work.

Finally, the board name you wrote is wrong, for the nRF91DK, you should use "nrf9160_pca10090ns", though I assume this is just a typo in your ticket, and not related to the issue.

Best regards,

Didrik

Hi Didrik , 

I didn't open the cmd not from toolchain manager , i opened cmd.exe there i was trying to build my project . i tried to open cmd through toolchain  -

1 .open my test project

2. then i have given command  -west build -b "nrf9160_pca10090ns"

but still following error came - 

Please let me know which configuration i am missing 

[Didrik Rokhaug]

In NCS v1.3.0, the boards changed name to 'nrf9160dk_nrf9160ns'.

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.3.0/nrf/doc/release-notes-1.3.0.html#boards

Try using the new name, and see if that solves your problem.

If that doesn't work, I need to know a bit more about what project your are trying to build, and your prj.conf file.

Hi , i have given the path west build -b "nrf9160dk_nrf9160ns" , i got the following  error

OK, this is probably because there are some build artefacts in the build folder, so West thinks that it finished the configuration step last time, which it didn't.

try deleting the build folder, or add '-p' to the end of the west command to do a "pristine build".

Hi ,

I added the -p at the end of west command ,still getting same error

Could you try without qoutes around the board name?

Also, are you setting CONFIG_UART_0_NRF_UARTE=y in your prj.conf?

[shruti mishra]

Hi ,

I tried without quotes , yes i setting CONFIG_UART_0_NRF_UARTE=y but when i remove it , few more build steps got added but inside build folder ninja file is not generated .

Before doing the build using cmd is it required to do configuration ? 

Best Regards,

What does your CMakeLists.txt file look like?

Another change between NCS v1.2.0 and v1.3.0 is how the Zephyr build system is included.

If your CMakeLists.txt file has two lines similar to these

include($ENV{ZEPHYR_BASE}/../nrf/cmake/boilerplate.cmake)
include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)

Try to replace them with:

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
