I was making a new project and use the option "File > New > Kinetis SDK 2.x Project", after this, I just tried to build (worked well) without change anything and after I tried to debug this project, but unfortunately this error appear and I can't solve it.
I found others links talking about "Launching: Configuring GDB Aborting Configuring GDB", but didn't help. All those links just said to copy that text in Commands' box:
set mem inaccessible-by-default off
set tcp auto-retry on
set tcp connect-timeout 30
I did this many times, restart the KDS, reopen a new project, unplugged the USB Cable, but I'm still stuck.
*Observation: Other projects, like "bubble" that I tested (a demo program), build and debug and it occurred without problems.
