CCS/CCSTUDIO: Error while debugging

Manaf,

When posting a question, it is always helpful to include details such as the version of tools used (in this case CCS), and specifics about the project (where it was imported from, is it an out-of-box example or your own custom project, etc) and the errors generated. 

In this case I see that you are building sensortag_cc2650stk_app. From where did you import this project? If imported from the SDK, which version of SDK? Each SDK version installs a specific version of TI-RTOS/XDCtools and you need to make sure the project build is using those exact versions that come with the SDK.

After checking the versions, if the error persists, please save the output of the build console to a text file and attach it here.
