Hi!

   

I have followed AN75705: "My First USB 3.0 Transfer Using FX3" carefully to test a simple loop back test using the CYUSB3KIT-003. Every step works fine, including download of the newly compiled FW to the board, until the actual bulk transfer, where I get error 997. I tried it many times, with two different CYUSB3KIT-003 boards. See the attached screen capture where I have also run USBLyzer on the traffic. I'm using a USB2 cable in a USB3 port, but I also tried the same cable on a USB2 board, with the same error result.

   

Do you have any idea what might be wrong here?

   

regards,

   

Torbjörn

I just found that I had failed to modify the cyfxbulklpauto.h correctly, as stated in the guide. Now with the correct modifications it works.
