Solution 1:[1]

you would need to check the following 2 settings in your project options:

  1. in project Options, Category:Debugger-> Setup->Driver, make sure you set driver setup to whatever driver youre using. I gave an I-jet and I set driver to I-jet
  2. in project Options, Category-> I-jet, Interface, select Probe Confog to Auto and Interface to SWD
