Hello,
I am using TUSB1210 for my FPGA test and using the "output clock mode".
My FPGA using the ULPI interface to connect to the TUSB1210, and TUSB1210 will be plug by an usb wire to PC.
I can see that my FPGA device have comlete the speed detect, and the detection result is "HS"(Which is I want).
But after the speed detection, I can not receive any "setup packet", I can probe the ulpi data from my FPGA.
The data is so wring that did not match any USB packet.(At same time, I use analyzer scan the USB protocol, which shows that there is SETUP packet on USB wire)
And after the packet transmit, my FPGA will receive the RXCMD "7D", which shows the RxError is 1.
I have scan the TUSB1210 output clock is 60MHz correct. And my FPGA receive the clock fine.
At this point, I dont know why my TUSB1210 can not receive packet correct.
Please help me to find the problem is.
Thank you very much.
Regards
Chiayu Lu
