TLK10022: TLK10022 EVM config and BER testing issue

Hi,

Thank you for the detailed configuration in your document!  I am looking into this and will provide an update by the end of this week.

Thanks,

Drew

Hi, Drew

            Looking for your update, Thanks.

Hi,

I apologize for the delay, I am still looking into this.

Thanks,
Drew

It's very Urgent and block our development, need your feedback Asap. Thanks

Hi,

Sorry about the delay on this.

I was able to replicate your problem and found that by enabling the test pattern generation and verification on the "Operation Mode Cfg" page, the "NaN" status on the BER Testing page disappeared.  If doing this doesn't resolve your issue, please let me know.

Thanks,

Drew

Hi, Drew

 Please show me  your BER testing page.

When I config that you mentioned above, the BER is not NAN ,but it's always ERROR because error counter is growing. Does this mean the function of TLK10022 is wrong? How to get Error Counter 0 or loopback correct?  Thanks.

Hi, Drew

      When I  disconnect HS wire,  the BER of HS is 65535, It's right, I think 4 lanes of LS are conbine to HS TX, and send to HS RX, and divide to 4 LS, then compare LS lane0 RX to LS lane0 TX. why I disconnected HS wire, the LS lane0 still 0?
