I don't know if it's helpful but I also still show a dummy0 as an interface. From what I can tell it's not useful but is related to a (kernel) module that runs at startup.

What "dmesg | grep eth" is reporting ?

There's about a hundred "link up - half duplex" messeges, I truncated for sanity.
dmesg | grep -i spi:Quoteenc28j60 Ethernet driver 1.02 loaded
dmesg | grep -i spi was outputing something about a chipselect 0 already in use error, I removed sun8i-h3-spi-spidev.dtbo from the /boot/dtb/ directory and that seems to have solved it. But I am not sure I fully understand what it the error was other than possibly two modules fighting over the same spi pins. But I could be way off, the pins are correct as far as I can tell, but someone was saying that one of them (the cs?) is often misconfigured to be used on other pins. Hopefully that issue is solved, although I wasn't getting those errors before, not sure why they suddenly popped up.

This. But the ethernet port itself reads 18/20.
It's an enc28j60, not sure what the board it's on is called. But as far as I understand they are pretty generic and (used to be) commonly used. According to the diagrams I found online everything matches (triple checked!).Orange Pi's Pinout <--- previous link broke?
Can't find an official diagram but follows this pinout-- I plugged up the ethernet port to a laptop and listening wireshark I can't see any traffic when pinging or making dhcp requests. Ifup just ends in no dhcp offers received, and a static address can't reach anything when plugged up to a switch. Should I assume this is a board/armbian configuration issue or could it just be a networking problem?

Only now the interface state won't come up. Ifup stalls out on dhcp requests, and I can't see any traffic coming from the nic.

You seems that have missed that overlays placed in /boot/overlay-user/ folder still need to be declared in /boot/armbianEnv.txt using variable "user_overlays=spi-enc28j60" .
I corrected that and now eth1 shows as an interface. Thank you!

Hello,
I am trying to connect an enc28j60 ethernet port to spi0.0 on an orange pi pc, running armbian (debian stretch 4.19.5).
I have the jumpers all connected in what I believe is the correct pattern. I compiled a device tree (overlay?) for the enc28j60 on h3, the dtbo file now exists in /boot/overlay-user/spi-enc28j60.dtbo.
/dts-v1/; /plugin/; / { compatible = "allwinner,sun4i-a10", "allwinner,sun7i-a20", "allwinner,sun8i-h3", "allwinner,sun50i-a64", "allwinner,sun50i-h5"; /* This fragment is required only if the IRQ pin requires internal pull-up */ fragment@0 { target = <&pio>; __overlay__ { enc28j60_pins: enc28j60_pins { pins = "PA7"; function = "irq"; bias-pull-up; }; }; }; fragment@1 { target = <&spi0>; __overlay__ { #address-cells = <1>; #size-cells = <0>; status = "okay"; enc28j60 { compatible = "microchip,enc28j60"; reg = <0>; interrupt-parent = <&pio>; interrupts = <0 7 2>; /* PA7 IRQ_TYPE_EDGE_FALLING */ spi-max-frequency = <12000000>; status = "okay"; /* These are required only if internal pull-up is used for the IRQ pin */ pinctrl-names = "default"; pinctrl-0 = <&enc28j60_pins>; }; }; }; };
and I configured the /boot/armbianEnv.txt. (I just recently added spi-jedec-nor/spi-add-cs1 just for the hell of it to test).
verbosity=1 logo=disabled console=both disp_mode=1920x1080p60 overlay_prefix=sun8i-h3 rootdev=UUID=1b49372a-ea5b-42f6-9e60-036606066891 rootfstype=ext4 overlays=spi-add-cs1 spi-jedec-nor spi-spidev param_spidev_spi_bus=0 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u
But the device still does not come up. I get a dmesg of "spidev spi0.0: probing from DT" and no errors anymore. And I configured the /etc/hosts/interfaces file, but ip a just shows an "unknown" state instead of up or down.
All the tutorials (for raspberry pi's on raspbian... seriously only 2 people have ever tried this on orange pi/armbian?) I can find only show these few steps. And I can't even think of how to go about troubleshooting this. I am kind of new though so maybe I am missing something. What else should I try?

Hi, did you have any luck getting this to work? I am working on a similar project and was interested in your progress.
Adding enc28j60 ethernet on orange pi pc

It doesn't let me set it to full duplex, gives me a not supported error. And I can't configure the network but I believe the switch is set to auto-negotiate.
But my current idea is that the spi pins need to be configured differently. It's currently set to 'pins = "PA7"'. And from what I understand this may need to be changed. Not entirely sure though.
