CZ11NIC12 is indicated on my board.

:-( Well, this board version has wrongly matched length of some
differential pairs, IRQ from 88E1514 is connected differently, there
are slight differences in power supplies and (if I am not mistaken)
something changed in RTC support circuitry. It looks like a huge
mistake on our side.

Hi Tomas

Would these problems also explain why the Ethernet links to the switch
don't work? Maybe the differential pairs?

no this is not the problem. When booting the OpenWRT based system I can
communicate with the device via the switch. (Didn't test deeply, but my
Laptop got a dhcp lease from the Turris Omnia and I can ping it.) But
this convinces me, that the hardware is good enough.

If you have any ideas what I can try to make the switch work or help to
diagnose the problem, just let me know.

Best regards
Uwe
