Build Configuration Issue Due to Incomplete SDK : kcmake.conf

[Milan Bhatnagar]

I have been facing a persistent Zephyr CMake/Kconfig build failure in my nRF Connect SDK setup.

Environment: Windows, nRF Connect SDK v2.7.0, Toolchain v2.7.0, using VS Code nRF extension.

My project (my_adc_blink_new) builds fine until CMake throws the following error:

CMake Error at C:/ncs/v2.7.0/zephyr/cmake/modules/kconfig.cmake:392 (message):
  command failed with return code: 1 

The detailed logs show that Zephyr cannot find the board configuration for nrf52840dk_nrf52840 or even nrf52840dk.
The actual path C:\ncs\v2.7.0\zephyr\boards\arm\nrf52840dk_nrf52840 and its files (like nrf52840dk_nrf52840_defconfig) are missing from my SDK installation.
I tried west update, west init -l nrf, dummy board files, and SoC-only builds (-b nrf52840)—but the kconfig.cmake error persists because the Zephyr tree is incomplete.

Hi, 

Do you also experience the same issue when building an NCS sample? If so, please try to reinstall the SDK. If the problem persists after a clean reinstall, double-check that your SDK directory contains the required board files.

No , NCS sample was build fine. Major problem is the recurring error due to absence of board file in C:\ncs\v2.7.0\zephyr\boards\arm\nrf52840dk_nrf52840, due to absence of nrf52840dk_nrf52840 &  nrf52840dk_nrf52840_defconfig. Tried updating SDK but this board files remain absent always. Is there any other way out to resolve this issue ? My SDK is v2.7.0 and Toolchain is 2.7.0.

It's strange that the issue only happens to your project. The board path is updated in the NCS v2.7.0 (C:\ncs\v2.7.0\zephyr\boards\nordic\nrf52840dk). It seems your project looks for the old board path setting before v2.7.0. I would suggest you remove the board path setting in your project or duplicate an NCS v2.7.0 sample as a base for development.

Greetings!

We were able to solve previous query and have following query now:

Can I use any of the header pins on P20 of nRF52840 DK as the on-board 3.3 V rail? If yes then which is most preferred for current and later use in the microprocessor for 3V-3.3V Vout

Please suggest.

Please create a new support case since the last issue is away from the original scope.

Done, we have created a new suppot case
