Hi All,
We would like to announce that we have added support for Freescale Kinetis devices to VisualGDB - a Visual Studio add-in that allows developing and debugging embedded projects with Visual Studio.
There's a detailed tutorial available on the FRDM-KL25Z platform here: http://visualgdb.com/tutorials/arm/kinetis/frdm-kl25z/ and another one on TWR-K40D100M.
If you have any questions or suggestions, feel free to post them here.
