Hello everyone, I am a beginner and am following the Youtube video to learn. This error occurred when I first tried to build.  please give me more guidance. Below is the information from the terminal:

Hi,

Have you tried building using west? Do you get the same issue?

Which board are you trying this on? 

Also, could you tell me where you got this blinky_pwm_tutorial project from, i.e. it's exact location. Or is it a custom project you tried? If it's a custom project, could you send the zip file of the project?

Best Regards,

Priyanka

[Siri Zhang]

Thanks for replying!  

This "blinky_pwm_tutorial" project is from the zephyr template "blinky_pwm”, only changed the project name by me.

I strictly follow the tutorial on YouTube to operate：nRF Connect for VS Code, part 3: Building an application - YouTube

Hi Zhang,

I could not replicate the issue. It builds successfully on my side. Could you try to follow the following steps?

Open the VSCode via Toolchain Manager in the nRF Connect for Desktop:

Then in the VSCode please make sure that you have the proper SDK version and Toolchain version selected before beginning.

After that, go to "Create a new application" and select the required sample:

After this, please check whether you get an error. If so, please attach the error log as well as the "Problems" window.

Thank you for your considerate and meticulous response!

I found the reason: When installing NCS, the Toolchain Manager displayed success, but in reality, the installation was not completed. There are still many missing files.

The specific reason is not very clear, but I suspect it may be a network issue.

After I found the complete compressed package of NCS on the internet and decompressed it to the correct directory, everything was OK.

Sincerely suggest that engineers pay attention to this problem.

Hi,

Glad to hear that you were able to get it working. I will convey this internally. In case of no further queries, please close the ticket.

Have a nice day
