[BPI-R64] OpenWRT and MT7531BE Switch

Ivan_Revyakin · October 22, 2019, 7:39am

Does anybody know how to work with MT7531BE switch in the OpenWRT? The Kernel has a driver and it logs messages of switch working (List 1 – plugging/unplugging cable, List 2 – kernel loading).

@sinovoip, @rainfall83, could you explain what are openwrt packages have to be installed?

Have you any Problems with it in openwrt?

I using same drive in my repo and have some issues getting sgmii-link (for lan-ports) up (in 5.4) when booting kernel from sdcard…tftp works

Ivan_Revyakin · October 22, 2019, 10:52am

I can’t say if there are any problems or not. I do not know how to work with the switch inside OpenWRT yet. Other words I don’t know how to get interfaces of each physical port of board inside OS. I see only eth0 and eth1.

frank-w · October 22, 2019, 11:04am

right, there is no dsa-driver…eth1 is wan-port,eth0 for all 4 lan-ports (like lan-ports are bridged together)

Ivan_Revyakin · October 22, 2019, 12:53pm

File “emmc_singleimage.img” (eMMC all-in-one single image) with OpenWRT (LEDE 17.01) has a tool named “switch”. This image from @rainfall83 's post, here: Bpi-r64 quick start (boot from eMMC)) . It can configure MT7531BE switch. Doesn’t it use the driver what you mean?

it use the same driver only with swconfig-patch (which i don’t use because the swconfig application does only exist in openwrt)

this application can be used to set vlans on the switch (default only pvid which are internally dropped to only separate lan and wan to each gmac) to separate ports.

just give eth0 ip address you want to use for lan and configure eth1 for wan-port (e.g. dhcp) for a first test

Ivan_Revyakin · October 22, 2019, 1:53pm

Ok, got it. I’ll try to start with eth0/1. But where I can get sources of OpenWRT’s “switch” and “swconfig” for MT7531BE? If there is an OpenWRT image contained it mean there is an sources for OpenWRT.

frank-w · October 22, 2019, 2:02pm

Swconfig is part of openwrt,you can try compile 4.19 kernel with mt7531 from main repository

Swconfig source is here,but you need mt7531 driver compiled with swconfig-option

Example why you need to compile kernel with ethernet-driver and swconfig-option:

github.com

I have not yet figured out how to compile swconfig outside of openwrt (to use with my kernels)

Btw. This i my thread regarding it: Compile swconfig for r64

Ivan_Revyakin · October 23, 2019, 7:36am

@frank-w, I built the img including swconfig from the main openwrt rep, but unsuccessful – “swconfig list” does not show me a switch. May be I miss somewhat in “make menuconfig”?

Maybe you have to propagate mt7531 to swconfig…i don’t know how swconfig gets switch data but it needs any api to communicate with switch

Maybe you could add a prink here: https://github.com/frank-w/BPI-R2-4.14/blob/8d8e1d48e8f31ee6631fccc300a6ee2fb6694c6a/drivers/net/phy/mtk/mt753x/mt753x_swconfig.c#L495

Just to see if registerswitch is called…

That are my changes. First one was test (and should be reverted) because i thought mt753x_apply_vlan_config was not called without swconfig. This is needed for port-separation. before i’ve updated driver all ports were connected to both gmacs…

second is adaption to 5.4 where netlink policy is moved to family

Ivan_Revyakin · October 24, 2019, 2:52pm

If I understood you correctly I did this:

    swdev->ops = &mt753x_swdev_ops;

    printk("-----======###### Mark 1 #####=====-----")
    ret = register_switch(swdev, NULL);
    printk("-----======###### Mark 2 #####=====-----")
    if (ret) {

But these marks did not appear at the log…

frank-w · October 24, 2019, 3:35pm

yes looks right

And you have compiled with CONFIG_SWCONFIG?

these lines should appear because with swconfig-option set mt753x_swconfig_init is only defined in line 14 and used from mt753x_swconfig.c

Ivan_Revyakin · October 25, 2019, 8:00am

Yes this was a reason swconf did not work correctly! @frank-w, thx! It’s a litle bit strange for me the switching on swconf and kmod-swconfig via “make menuconf” does not switch on SWCONFIG (Switch configuration API) for Kernel… I had to do it via “make kernel_menuconfig”.

frank-w · October 25, 2019, 10:34am

That can be changed in Kconfig that swconf also selects SWCONFIG but maybe this should not be done by some reason

Can you post output of swconfig?

@Ivan_Revyakin @frank-w, Thanks, that provide a way to query the switch port link state for me.

But Is there a way to get notify when the switch port cable removed? I have try the ifplugd, failed, ifplugd can’t get notify when the switch port cable removed.

@sinovoip, If use the DSA-driver, can i query the switch port state from /sys/bus/mdio_bus?

I guess you should can use ethtool or ip link to get status of interface…i don’t know how to use ifplugd or similar. Does it not work with dsa-driver? I’m guess it can not work with openwrts phy-driver
