About dynamic reconfiguration of transceiver

Hi,

Thanks for your update.

When you refer to CDR cannot lock, just to clarify if you are referring to the not able to lock to data?

Are you using the XCVR reset controller? If not, it is recommended to use the reset controller to correctly sequence the reset.

In addition, it would be great if you could check on the CLKUSR and CDR refclk to ensure that they are directly sourced from free-running oscillators on board. This is to ensure successful power up calibration and re-calibratioin.

By the way, are you using embedded streamer + multiprofiles to reconfigure? If not, you can try this where the embedded streamer will take care of all the reconfiguration with few registers writing.

I would recommend you to use the latest Quartus version to see if there is any difference.

Please let me know if there is any concern. Thank you.
