Dear Biser-san,

Thank you for your reply.

I read wiki page that you pointed me out. But I can't find any registers information of AM57xx.
My customer uses WEC7 as OS. I think AM57xx can output eye diagram for testing. Is my understanding right?
If it is yes, I need registers information for USB eye diagram testing.

I appreciate your quick reply.

Best regards,
Michi

Yama-san,
The DWC registers are protected by NDA so a SW interface for entering the various test modes is provided for the TI-supported OS (as referenced by Biser above). Please have your customer contact their OS provider for information on how to enter USB test mode(s) on that particular OS.
