Lamobo R1 broken networking on 21.02

[mil4898]

Hello Guys,
After installing 21.02 latest snapshot into a lamobo bananapi R1 , I noticed that networking is not working . In the dmesg I can see errors referring to swconfig:

From the look of it swconfig seems to be broken:

# swconfig dev eth0
swconfig list

I initially thought that R1 may have been moved over to dsa however , everything points to this device using swconfig approach instead .
for one the auto-generated config for the network:

root@OpenWrt:/# cat /etc/config/network 

config interface 'loopback'
        option device 'lo'

Also there does not seem to be any trace of dsa in here:

root@OpenWrt:/# 
root@OpenWrt:/# find / -name "dsa*"
root@OpenWrt:/# 

And I can not define any dsa type ports:

root@OpenWrt:/# 
root@OpenWrt:/# ip addr add 192.0.2.1/30 dev lan1
ip: can't find device 'lan1'
root@OpenWrt:/#

So I am suspecting that this device is not meant to be on dsa just yet . And that the issue we have is a broken swconfig .

Falling back to 19.07 , the networking comes up nicely , and all works ok especially swconfig
. I have not tried the older 21.02 RC images , only rc3 and today's snapshot . Which theoretically would be the most uptodate , and have latest bugfixes .

I would be grateful if you could assist in getting R1 working on 21.02 . Much appreciate any help .

you'll probably need too reset your device to get networking back again, in 21.02.

Network migration 21.02.0-rc2

I've tried to migrate my Archer C7v2 network config by pressing the "migrate" button that was offered by LUCI after upgrading from 21.02.0-rc.1 to 21.02.0-rc.2. After that, my device went unreachable (no web UI, no ping). My original network config I copied off the device before starting the migration was: config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fd63:8f35:a549::/…

Mini tutorial for DSA network config

Update from 2021-05-31: Option ifname was renamed to device This tutorial is valid for 21.02-rc2 (or newer) and recent snapshots Introduction DSA stands for Distributed Switch Architecture and is Linux kernel subsystem for network switches. It's an upstream replacement for OpenWrt's swconfig framework and many new routers use DSA drivers instead of swconfig drivers. In DSA each switch port is a separated Linux interface. It means ip / ifconfig command will show interfaces like lan1, lan2, w…

[mil4898]

Much thanks for the suggestion . Now I have loaded 21.02 RC3 , and set the ports up , as per above .
With the networking as it is on 21.02 I can not connect to luci , since none of the ports work , and that is the only way in and out . SO I am working through cli serial port .
Here is my config , i just need one port up to see if i can get to luci:

root@OpenWrt:/# cat /etc/config/network

config interface 'loopback'
        option device 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd3b:21e9:8eea::/48'

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'eth0.1'
        list ports 'lan1'
        list ports 'lan2'
        list ports 'lan3'
        list ports 'lan4'
        list ports 'wan'

config interface 'lan'
        option device 'br-lan'
        option proto 'static'
        option ipaddr '192.168.6.1'
        option netmask '255.255.255.0'

This is not working either . I suspect now something is wrong with the driver .
In 17.09 we used the B53 drivers , and we can see that in the dmesg:

root@OpenWrt:/# dmesg | grep -i b53

There is more to it , than config it seems .

Hello Guys,

Update:

I am pretty much sure now that the R1 is not supposed to be on DSA , it is meant to remain on swconfig . However we have a broken connectivity to PHY . I have been looking at the .dts file that comes with imagebuid , and we can see it has old config in there for gmac:

&gmac {
	pinctrl-names = "default";
	pinctrl-0 = <&gmac_rgmii_pins>;
	phy-handle = <&phy1>;
	phy-mode = "rgmii";
	phy-supply = <&reg_gmac_3v3>;
	status = "okay";

	phy1: ethernet-phy@1 {
		reg = <1>;
	};
};

Also looks like in 2018 , there was some work done on the code . The .dts file went from swconfig to dsa , and back again . There are patches for reverting changes , then patches for reverting the reverts . A bit confusing to know what the result is once all these patches are applied .

[mil4898]

The DSA version of the gmac config would look something like this:

&gmac {
 	pinctrl-names = "default";
 	pinctrl-0 = <&gmac_rgmii_pins>;
 	phy-mode = "rgmii";
 	phy-supply = <&reg_gmac_3v3>;
 	status = "okay";
 
	fixed-link {
		speed = <1000>;
		full-duplex;
	};

 	mdio {
 		compatible = "snps,dwmac-mdio";
 		#address-cells = <1>;
 		#size-cells = <0>;
 
		switch: ethernet-switch@1e {
			compatible = "brcm,bcm53125";
			reg = <30>;

			ports {
				#address-cells = <1>;
				#size-cells = <0>;

				port0: port@0 {
					reg = <0>;
					label = "lan2";
				};

				port1: port@1 {
					reg = <1>;
					label = "lan3";
				};

				port2: port@2 {
					reg = <2>;
					label = "lan4";
				};

				port3: port@3 {
					reg = <3>;
 	               			label = "wan";
				};

				port4: port@4 {
					reg = <4>;
					label = "lan1";
				};

				port8: port@8 {
					reg = <8>;
					label = "cpu";
					ethernet = <&gmac>;
					phy-mode = "rgmii-txid";
					fixed-link {
						speed = <1000>;
						full-duplex;
					};
				};
			};
		};
 	};
 };
 

And it is clear that we do not have that .

I wander if the b53 drivers used on the R1 are broken with respect to kernel 5.4 ?
Some files in there have not been touched for years .

[mil4898]

Update:
The old b53 drivers , seem to be a no hope exercise . I have not been able to compile them to work with swconfig .
So I have moved over to DSA drivers . And have had success here .
I was able to get a fresh git pull of the openwrt snapshot source , and selectively apply Hauke's patches from his git tree , and compile a working driver set up .

My dmesg is now looking good:

I can get the R1 to work a a dumb switch , and access the system , run luci as well as install packages .

However I am struggling to understand how to create the network config file in dsa syntax, to do what the old one did using swconfig .

I would be very grateful for any assistance in converting this network config file:

root@OpenWrt:/# cat /etc/config/network 

config interface 'loopback'
       option device 'lo'
       option proto 'static'
       option ipaddr '127.0.0.1'
       option netmask '255.0.0.0'

config globals 'globals'
       option ula_prefix 'fdaf:84b6:fc01::/48'

config device
       option name 'br-lan'
       option type 'bridge'
       list ports 'eth0.1'

config interface 'lan'
       option device 'br-lan'
       option proto 'static'
       option ipaddr '192.168.1.1'
       option netmask '255.255.255.0'
       option ip6assign '60'

config interface 'wan'
       option device 'eth0.2'
       option proto 'dhcp'

config interface 'wan6'
       option device 'eth0.2'
       option proto 'dhcpv6'

config switch
       option name 'switch0'
       option reset '1'
       option enable_vlan '1'

config switch_vlan
       option device 'switch0'
       option vlan '1'
       option ports '4 0 1 2 8t'

config switch_vlan
       option device 'switch0'
       option vlan '2'
       option ports '3 8t'

root@OpenWrt:/# 

I just do not get how to do it .

I have tried some armbian guides , as well as openwrt forum posts on the subject , however it is all still clear as mud .

Much appreciate your help .

Hello Guys,

Looks like I can not get the vlan stuff to happen on kernel 5.4 . It may be that there is some dev work needed on the sw to make it fully dsa ready . There is a quote from Florian in May 2018, not sure if the status is the same today , but here it is:

Yes, remember, b53 does not currently turn on Broadcom tags, so the only
way to segregate traffic is to have VLANs for that.

That would work once Broadcom tags are turned on which requires turning
on managed mode, which requires work that I have not been able to get
done

I am not able to use the nice and easy dsa method of config . Also when i tried the manual method by creating the eth0.1 and .2 interfaces then creating bridge and assigning vlans to ports , that did not work either .

What I can do is make a dumb switch out of it by adding eth0 to the bridge along with the lan ports .

To reproduce the behaviour with kernel 5.4 and dsa , what was easily done with openwrt 19.07 and swconfig I have not been able to manage .

SO I have decided to give up .

Best Regards
Mil
