Hy Ladies and Gentlemen

My Sbc ( a Clearfog pro cn9130) has 1 sfp cage, 1 dedicated Ethernet port RJ45
and 5 Switched Ethernet RJ45.

I can't get the 5 Switched Ethernet RJ45 to work.

I have post the Block Diagramm in the attachment of the post .

Here the dmesg

Here the dts

I think that the error which causes the problem is :
A priori, the default would come from the dts.

When i do the command line lsmod, i see the driver mv88e6xx, which manage the switched ethernet port.

I've been going around in circles for one week and don't find anything.

I've tried :
-to modify the dts, reg of the switch,
-to apply patches found on the web (driver mv88e6xxx),
-to use different os : Debian, Ubuntu and a custom os build from Buildroot.

I have found the Os Debian and Ubuntu on the manufacturer's website

I have post on his forum, but noting.

If someone has an idea

Thanks by advance

Doudoo
