Link Speed for AXI Memory Mapped To PCI Express (2.6)

Hi

 

I am attempting to use this core (on the ZC706 board) with128 bit AXI.

 

I can only set the link speed to 5 bits/s (per lane I hope/think) when I  select 4-lane pcie.

 

When I untick the ZC706 development board option and select 8-lane pcie (for my custom hardware)

I can only get a link speed of 2.5 Gbits/s (per lane I think)

 

Surely this defeats the idea of 8 lanes instead of 4?

 

 

Thanks

 

Dean
