TWR-K60F120M, TWR-SER2 High Speed USB issues.

michaelcollins — Tue, 17 Mar 2015 02:13:54 GMT

I have run into a problem with the ULPI on my TWR setup. I am using the TWR-K60F120M, and TWR-SER2. I have tried porting the USB stack 4.1.1 bare metal K70 ULPI demo over to the K60. When I plug in the device I get a USB Suspend interrupt, a USB Reset Interrupt followed by 4 Port Change Interrupts spaced 4 seconds apart. At that point, windows gives a device descriptor failed error. I have breakpoints and no attempt to read the descriptor has happened. I know others have ported this demo to the K60 and was wondering if there is anything special I need to look out for. I've ensured my debugger isn't an issue by removing its connection to the trace lines. Looking for any other advice. Thanks!

Hi Michael,

I also did a porting for TWR-K60F120M, and run the Host MSD demo(C:\Freescale\Freescale USB Stack v4.1.1\Source\Host\examples\msd) with TWR-SER2, the result is ok . Please kindly refer to the following for details.

Which demo did you port? Is it the same demo? Please kindly help to clarify.

Have a great day,
Kan
