I closed and reopened CodeWarrior and it was complaining about not being able to open my workspace. I had to delete my .metadata folder and rebuild my workspace. Since, then I've been unable to reproduce the issue.</P><P></P><P>The IDE being unable to open my workspace happens to me on average once every few months, but I've never seen a debugger issue present itself like this before. Anyone else seen similar issues?</P></BODY></HTML> Thu, 12 Mar 2015 01:29:53 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/MC13213/m-p/379175#M21219 ignisuti_ 2015-03-12T01:29:53Z
