BCM5396 EEPROM file template/SerDes Port Issues

ryanl

Thanks again for all of your support here in this thread: BCM5396 EEPROM file template

We have since moved forward a little with the BCM5396, but we are struggling to get the SERDES port up and running.
Are you able to help with a list of register changes required to switch ports
to SERDES mode.

Thank you.

Hi,

Can you please advise your configuration? 5396 SerDes port connect to SFP module or external gphy?

Thanks,

Ryan

Re: BCM5396 EEPROM file template/SerDes Port Issues

Thanks for getting back to me.
The SERDES connects over a backplane to another SERDES interface, no phys
involved.

However we do now have a
development… the hardware engineer says our
MDC/MDIO has a
wiring error, so he has made a strapping change (
AUTO_POL_DIS) and
this has allowed the SERDES links to establish connection, so we are moving
forward once again.

Thank you.
