Problems building the radio test sample project for nRF5340 and nRF Connect SDK 1.7.1

[cscase]

Hi all,

I'm new to nRF Connect and the associated toolchain, so I apologize in advance if this question is tiresome or has already been answered, but I've not had any luck finding relevant info online.

I'd like to build the radio test sample project for the nRF5340-DK.  I am running VSCode with nRF Connect SDK 1.7.1 under Windows 10. When I've created the project and attempt to build, I get the following in the console. I've highlighted what looks like the central issue to me, but am pasting the entire text in case there are other helpful details here.  Below the transcript from the build attempt, I will also past the output from 'Generate support information.'

I received help from an FAE who was able to identify the source of the problem. It was this:

I have the nRF Connect SDK in one place, C:\sandbox\nRF_Connect

My project was located elsewhere, in C:\nordic\MyApps\radio_test4. 

The problem was that the paths in the sample project were relative to the SDK directory, so trying to build in another folder outside that invalidated these relative path references.

A quick temporary fix for this was to add the radio test as a new app and walk the SDK through down to its location in the SDK. It took a little fiddling around but using this approach we were able to get a good build.

Greetings cscase,

I have the same exact issue.

Could you please explain how did you walk the SDK down to its location I am trying to do the same thing, some more detailed instructions would be greatly appreciated!

Kind regards,
