In Configuration Settings page, there is a menu named <STRONG>Select Optional Middleware.&nbsp; Please </STRONG>add Freertos and USB stack into SDK.</P><P>Then click Go to SDK Builder.</P><P>By this way, you will get the Freertos and USB stack you want.</P><P></P><P>Regards</P></BODY></HTML> Wed, 07 Jun 2017 02:29:48 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/kl25-usb/m-p/675639#M41546 jingpan 2017-06-07T02:29:48Z
