Rock64 dwc interface issues

Fri Jun 19 13:48:40 UTC 2020

You might not be alone :) I got my shiny new rockpro64 (yeah a little different) and it probes the dwc device just fine (todays -current)

dwc0: <Rockchip Gigabit Ethernet Controller> mem 0xfe300000-0xfe30ffff irq 9 on ofwbus0
miibus0: <MII bus> on dwc0
rgephy0: <RTL8169S/8110S/8211 1000BASE-T media interface> PHY 0 on miibus0
rgephy0: OUI 0x00e04c, model 0x0011, rev. 6
rgephy0:  none, 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT-FDX, 1000baseT-FDX-master, auto
rgephy1: <RTL8169S/8110S/8211 1000BASE-T media interface> PHY 1 on miibus0
rgephy1: OUI 0x00e04c, model 0x0011, rev. 6
rgephy1:  none, 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT-FDX, 1000baseT-FDX-master, auto
dwc0: bpf attached
dwc0: Ethernet address: X:X:X:X:X:X

It does not work however, no error msgs or anything, but no traffic enter or leaves at all.

I had a similar issue with the dwc compat chip on the Allwinner R40 (Bananapi M2 Berry) and got that working, so I’ll se if similar hacks works here…
