Fail to load nRF Connect SDK project

[Chongchun Moon]

Hello,

  I am using SEGGER Embedded Stuido for ARM(Nordic Edition) V5.68 for NRF9160 evaluation.

  

  It was Okay for while. But, suddenly, I met error message(SyntaxError: Unable to parse JSON string) whenever I try to select "Open nRF Connect SDK project..." in File

  I replace SES and nRF Connect SDK But, it keeps happened.

  I don't know how to resolve that issue. Can you help me out to resolve that issue?

 

  Thanks in advance.

Regards,

  Chongchun Moon

Hi Chongchun and Xiaofeiyu，

Have you tried to completely delete SES and NCS and reinstall to try? Can you specify this issue happens on macOS or Linux on ARM?

I found a solution mentioned here https://devzone.nordicsemi.com/support-private/support/232162#permalink=507584, not sure if this fits your cases.

Best regards,

Charlie

hello Charlie， 

i indeed tried the solution you mentioned, but still failed.  BTW, i found it has some relationship with the cmake. if delete the cmake, then there will be a pop-up dialog showed below when trying "open nrf connect sdk project"

Then i re-install the cmake tool and fill in the cmake patch in the dialog, the "unenable to parse the JSON string" dialog appears again. I tired server different cmake versions,still failed.

Yes, I did it several times. It happens on Windows. As you may know, That version of SES doesn't have installer. I just download it and unzip to use it. So, I tried to remove setting and user data through SES. But, It looks that some configuration are kept somewhere. And I tried to reinstall NCS and older version(NCS V1.8.0, NCS V1.7.0) of it.

But, Still happens same issues

I just rolled back my system to one weeks ago using Windows restore function.

Now, It looks okay.
