TUSB1046EVM INT053 Rev AB

Hi TI expert,

I bought TUSB1046 EVM before. But the real board is totally different from the board on website (https://www.ti.com.cn/tool/cn/TUSB1046EVM?keyMatch=TUSB1046&tisearch=Search-CN-everything&usecase=part-number).

And I was told the board in my hand is same with the board on website. 

But we tested the board with DP source and type C sink. The PD negotiation is correct. But DP link training failed becauase of no CR and EQ done.

So my questions are:

1. Is the board in my hand correct TUSB1046 EVM?

2. Where can I get the document about the board in my hand?

3. How to configure the board to work normally?

Thanks.

    Hello，the revision of the website is INT017 REV_A, while you have bought is INT053 REV_B. But the website describes that the EVM include is INT053 indeed. 

    So I think  you should buy the latest version, do you configure the board according to the EVM user's guide？

    Please configure it using the EVM user's guide to confirm if your demo work normally. If not, please contact me again, and at the same time, I need to confirm which version is the latest version. Sorry for your incovenience that have caused to you.
