How to enable 1x SRIO in T2080RDB

[flabyjacob]

Hi,

My T2080RDB base custom board is using 0xE0 & 0x36 combination of SERDES protocol. With this combination of protocol selection, SRIO is 4x. How can  I make SRIO to 1x in this SERDES protocol

Just use only SerDes2 lane D (3).

Hi Fedor,

Thanks for the fast response...

From your answer, I assume that you are saying to connect only one lane (one physical connection) between processor(host) and FPGA(agent), rest three lines should not be connected between host and agent.

But I want to know, is there a way to control and select a particular lane from software? By configuring any registers or so?

Thanks & Regards
