Hello:
I am hoping that the guys from BRTOS lurk here. I tried loading the quikstick example that has SD+USB_CDC example. It compiles correctly and downloads but I get the error "unkown device" when I plug into my system. (Windows 7 - 64-bit).
I have yet to get a working USB example with the kinetis. Has anyone else seen this problem?
The problem seemed to be hardware. I hacked another circuit with the same chip and it worked. The CDC driver didn't work but the link you pointed me too seemed to work ok. Thanks. Just trying to find an example that I can backport to a bare metal implementation.
Hi,
I am Gustavo from the BRTOS project. Regarding your question about a bare metal USB CDC, i must say that BRTOS driver is based on the bare metal driver provided by Freescale:

So, you can download the Freescale code and use the USB CDC demo.
Regards.
Thank you for the info. I did get everything to work.
