On changing prj.conf, is it necessary to rebuild code?

I am working on nRF9160 and i found that when i change prj.conf, i need to rebuild code. if rebuild is not done(only build  is done), changes made in prj.conf does not comes in picture.

My concern is every time rebuild is taking much time.

Can you please suggest other option if any?

  • Are you using west or SES? In west the only thing you have to do is to run "west build -b <your_board>", but if you are using SES you have to choose "File-->Open nRF Connect SDK Project". 

    I am aware that rebuilding takes some time, only for changing a simple configuration and I am not aware of any faster way of implementing changes to the prj.conf into your project. Another option is to use menuconfig, but this is only for temporary changes and will get deleted if you clean your build folder.

    Best regards,
