I closed kinetis design studio with previous session in debug mode
on trying to open kinetis desing studio, its getting hanged, none of the menu is active
(I have opted for - open previous session - on opening kinetis design studio)
I had tried by closing all instances through task manager, PC restart - then also it had not applied.
Then I tried with Repair (installation process), no help
Finally, uninstalled and reinstalled.
have you made sure that your previous instance is not running any more (e.g. checked/killed with the task manager)?
Other than that, you can check this: GDB Client and Server: Unlocking GDB | MCU on Eclipse
I hope this helps,
