Hi vikash

Please download SDK from https://mcuxpresso.nxp.com.  Click SDK Builder button and follow it step by step. You will get it.

Hi vikash,

I suggest you move your project to SDK2.2 if your project is just start or have enough time to immigrate. Because the USB driver in SDK2.2 is better than in SDK1.3.
