I am trying to loopback the aurora just to debug,but i am not able to see any aurora packets transmitting.When i put chipscope and cheked it is because channel_up is not initialising and it depends on lane_up,so the whole process is interlinked so i can't change the core??
My IP version is 5.3,device spartan-6(LX45T-fgg484) and aurora lanes-2,lane width-4,clk-125MHz( my old version aurora lanes-2,lane width-2,clk-125MHz is working fine) i just want to change lane width.pls any one help

Give me some more info and I might be able to help. Data rate? Duplex or simplex? 8b/10b or 64b/66b? When you chaged to x4, did you update your UCF with the additional clock constraints?

Do you need the 4 byte width to meet specific timing or can you take the 2-byte output and just pass it through a grouping module to make it 4-bytes?

please try Aurora example design. it is a full design with ucf properly set.
