Hello Shu,

Could you tell me more about this project you are trying to build? Does the project open in SES?

ok,i open the nrf connect SDK project ,the is err above.I see that there is no ncs version and can't get the directory of NCS.

I also install the zephyr as zephyr project,is this problem?

this is all information

So I assume you have installed nRF Connect for Desktop by downloading it from here. Then you have opened the Toolchain Manager, downloaded an NCS version, and opened the version in question using SES. Then you've opened a project using the "File" dropdown menu, then pressed "Open nRF Connect SDK Project".

I try as you describled.but there is the same error.

Before,i have install serial the app such as Progrommer.I open toolchain Manager,then open SES.

the next i click the files,finnaly open the NRF connect sdk project.The error is the same sa  what i refer.

The Zepjhyr is 3.0.9 version.i use it as it describlr.the link is here.https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_recommended_versions.html

At what point do you get that first error you mentioned?

I see. Could you try reinstalling NCS? I believe there is something wrong with your installation.
