I've done a fresh install of KDS_v3 from kinetis-design-studio-3.2.0.pkg (on Mac OS X, of course! ). When I launch it, it presents an error dialog:
An error has occurred. See the log file null.
And though it may be unrelated, I see "MacOS error: -67062" messages in the console around the time I try to launch KDS.
I *can* launch KDS from the command line with the somewhat obscure command:
$ /Applications/KDS_v3.app/Contents/eclipse/kinetis-design-studio -configuration ~/workspace/.metadata/configuration
but I'd rather not have to do that every time.
I suspect some permission problem, or perhaps an outdated Java. I also think I've read about this problem somewhere, but haven't been able to find the thread that describes it.
