WAN Port not detected for Nanopi R5C

[StanleyLIM]

Hi, 

 

Just received my Nanopi R5C. Flashed the Debian 12 (Bookworm) Minimal/IOT images with Armbian Linux v6.12 from here https://www.armbian.com/nanopi-r5c/. Everything works well except that I could not get the WAN port working. Anyone has any idea?

 

BTW, the Nanopi R5C looks different from the image showed on https://www.armbian.com/nanopi-r5c/. Mine has only 2 x 2.5Gb ports instead of the 3 port. The image on the page looks like a NanoPi R5S... Just a side note. Cheers.

Those use systemd-network and it is called 'minimal' so it might be that only 1 port is handled by default (the LAN only). Rest you need to figure out yourself.

What do you want to do with the NanoPi-R5C ?

 

I have replaced systemd-network with NetworkManager as is the default in Debian Bookworm once for a newly downloaded image (was for ROCK3A AFAIR). The Ubuntu based images use netplan.io, that is nice for Canonical, not for me. I do not want to waste my time on yet another configuring/scripting/layering. It made me just clone an existing Armbian/Debian/RPi Bookworm rootfs as I use NetworkManager for almost all Linux computers and is easy copying of .nmconnection files between platforms (x86, arm, etc).

With logs, we could see if this is NIC not recognized or network stack problem.

I'm brought the NanoPi-R5C to setup Internet-in-a-Box on for an Orphan school. I would like both the network port to work so that 1 part can be connected to the internet and the second can be connected to their local router.

Base on the documentation, the 2 LAN port uses the same RTL8125BG. I assume driver shouldn't be the issue..

To be more precise - parameters that are provided to that driver. If driver would be the problem, both NICs would be down. You need to find / create correct settings (device tree), based on schematics. This forum (search) can provide plenty of resources and hints how to do this. Someone from community (with the device so testing can be done) has to sacrifice afternoon or more to get this in operation.

@StanleyLIM I see it should run a variant of OpenWrt, see https://www.friendlyelec.com/index.php?route=product/product&path=69&product_id=290

My NanoPi-R6C got delivered with that FriendlyWrt pre-installed on eMMC. I bought the R6C as alternative for RPi5, nice metal passive cooling and M.2 M-key as well. FriendlyWrt uses a bunch of partitions to store various objects related to the boot stage and although it would be nice for a router, I wanted generic Linux as base. But R6C is using RK3588S as SoC, yours RK3568B2.

 

Based on experience with my ROCK3A (RK3568), you could first check if both NICs are available on PCI-E, 'sudo lspci' should show.

If available, 'sudo ip link' should also show the 2 NICs as network ports. Then it is a matter of high-level networking, not really specific to Armbian.
