Hello All,
Here is a document for creating an USB Host Project (MSC + fatfs) with KSDK 1.3 and Processor Expert support in KDS. It uses FRDM-K64F board as example and lists some specific considerations that needs to be accomplished when creating an USB Host project by using fsl_usb_framework component (Processor Expert) in Kinetis Software Development Kit (KSDK) version 1.3.
I hope you can find it useful!
Regards,
Isaac Avila
