FSL USB Stack and k64

ERussell — Wed, 13 May 2015 23:39:18 GMT

I have been using the FSL USB Stack Version 4.03 (Device) on a k60 processor for a couple of years and am now trying to get the same code running on a k64. So far I am unable to enumerate. I do get an error interrupt - DMAERR but am not sure how to investigate this further. Has anyone used this version of the USB Stack on a k64? Any ideas about how to figure out the problem?

Thanks,

Elizabeth

Disable the MPU

MPU_CESR = 0;

Hi Elizabeth,

The USB Stack Version 4.03 is an older USB stack.

So far, customer could consider to use USB Stack V5.0 or Kinetis SDK software, which provides the USB application for K64 product.

Wish it helps.

Have a great day,
Ma Hui
