We developed many application on Kinetis with MQX.
An old project, using the USB bootloader for the K60n512 was used.
It was my previous teammate which work on it. I don't know on which project he is based, but I think from a sample provided by Freescale. (I Can send the source code to identify which project based?)
I think this is related to this post:
The problem is the new USB key which are in USB 3.0 (But "certified" as fully 2.0 compatible) not working on it.
Is somebody have an Idea to help me?
