I recommend that you have a look at the USB project(s) in the Kinetis SDK (http://www.freescale.com/ksdk).

Other than that, I have shared a Processor Expert project on GitHub, see

USB CDC with the FRDM-K64F, finally! | MCU on Eclipse

I hope this helps,

Hi Erich it's still me!

As you know I did your tutorial for FRDM K64 and it works but later I did it on my special PCB including K64F and the device is detected but not recognized... I would liek to get your opinion about my schematic. It can be an electronic problem.

PS: It's the same K64 version (FN1M0VLL12) and the same code that on your tutorial and on my frdm-k64f so I don't understand :smileysad:

Hi Erich,

Thanks for immediate response, but i'm currently using CodeWarrior 10.6, and don't khow how to use KDSK with that.

Can you provide some working USB CDC example for that?

Also need some guidance on implementing ethernet for the same.

thanks
