Bringing up a 10G link between 2 Ten64s

Ten64 Forum

I do see the Retimer line on a cold boot with the DAC plugged in:

Using SERDES1 Protocol: 29 (0x1d)
Using SERDES2 Protocol: 20 (0x14)
PCIe0: pcie@3400000 Root Complex: no link
PCIe1: pcie@3500000 Root Complex: x1 gen2
PCIe2: pcie@3600000 Root Complex: x2 gen3
Retimer: DS110DF410 found
OK

I see the exact same lines on a cold boot with the DAC removed.

When I insert the DAC after the boot has completed, I see on the console:

[  100.225389] sfp dpmac2_sfp: module FS               SFPP-PC01        rev P    sn Y2105169778-2    dc 210621

Checking the link with ip and ifconfig shows:

root@OpenWrt:/# ip link show eth8

Attempting to bring the link up:

I’ll experiment with the firmware images you mentioned above and let you know how it goes.
