Hi folks,
I figured out how to get a working configuration with FRDM-KL25Z board.
I'm new on this platform and I want to use OSX or Linux for developing.
I do the following steps to get working:
By default the FRDM-KL2x boards are not supported, for support install the KDSK 1.3 (KSDK 2.0 is released but not tested yet)
After installing run KDS again, go Help->Install New software->Add->Arhive
and browse to the file "KSDK_INSTALL_DIRECTORY"/tools/eclipse_update/KSDK_1.3.0_Eclipse_Update.zip
List of supported boards after integrating KSDK-1.3 into the KDS.


A stable version is available if you have any problem with the -dev version. gnuarmeclipse-openocd-osx-0.9.0-201505191004.pkg
- Add eclipse support for OpenOCD Debug.
Download the file and install the plugin (Help->Install New software->Add->Arhive) ilg.gnuarmeclipse.repository-2.11.1-201512141335.zip
Seclect the OpenOCD Debug and others if you want.


after install you need to set the correct path for the openocd binaries.
Go to the Kninetis Design Studio -> Preferences menu and set the path.

- Now Ready to start
- Start a new project as NEW->Kinetis SDK 1.x Project
- Choose a name
- Choose a Board or processor
- Select the Kinetis SDK with ABSOLUTE PATH and add PE support
- (of course you need to set your own installation path)


- at the next step choose the GNU C compiller
- After Finish make a new debug configuration in your project's settings as follows
And... Finally get working
