Now I got in reply to Test and could not figure out:
VisualGDB version: 5.3.15.1896
—————— System.Exception ——————
System.Exception: Stub exited before a gdb connection could be made
at VisualGDB.Common_GUI.WPF.DebugMethodTestWindow.ThrowTestFailedException()
at VisualGDB.Common_GUI.WPF.DebugMethodTestWindow.TestThreadBody()
openocd launches fine from the command line.
