Ethernet through the dock?

[dukla2000]

Reading OP - I still cannot understand why you are unable to run when powered: my power is old Samsung wall wart with Pine64 pinephone red cable, so again nothing fancy! What seems to work for me is plug everything (including power) into the dongle, then plug it into the phone. I think the phone is only enumerating stuff when it first connects to the dongle as I can get USB pendrive and keyboard/mouse to work this way, but not if I hotplug them after the dongle is connected to the phone. Similarly HDMI does work on my dongle. Last, when I plug in my dongle I often get a lot of clicking and a load of ANX messages in the log: about 50% of the time things have settled after 30 seconds and all the bits I expect to work are OK. Otherwise I unplug and try again. I have been neurotic that I have a physically loose connection but in fact think it is the ANX code that can be temperamental as I have had "the clicking symptom" kick off when the phone & dongle were flat on the desk and AFAIK the only movement was the earth rotating!

And another ps on the ethernet speeds I can get. Have radically improved with a cable swap   Using a cat 5e cable instead of an ever so flexible POS means the RockPro64 goes for Gigabit

Code:

[141547.178699] rk_gmac-dwmac fe300000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx

and iperf does a lot better - constrained now by the USB-C methinks?

Code:

$ iperf3 -i 10 -t 60 -c 10.42.0.44
