Hi Vivek > - It has two switches in order to support 8 lan ports. Internal switch is > BCM53012. The external switch BCM53125 currently works as "dumb switch" Do you know how the second switch is connected? Is it cascaded off the internal switch? Or does it have a dedicated Ethernet interface? Thanks Andrew
Andrew, I'm not entirely sure. But here is what I observed. Bootloader sets up both the switches. And I can use all 8 ports of the router when I boot Lede. Only the internal switch is detected and configurable via swconfig tool Internal switch is connected to CPU via port 5 same as Netgear R8000. The other bit here is that I looked through the GPL source and gpio pin 10 is labeled as EA9500_RST2LANSW_GPIO10_PIN/ResetSwitch. So when I performed a robo reset of the pin and 5 ports (labeled 1 thru 5 on the unit) of the 8 physical ports stopped working (no packets). If the external switch were to be connect via dedicated ethernet interface it should have shown up during the probe. Is in't it? Unfortunately my understanding about network devices limits me to investigate this further. I'll be more than happy to perform any tests if needed. Thanks, Vivek P.S sorry for duplicate email if you did get this first time around.

Is in't it? Not necessarily, and probably not with LEDE which would treat the external 53125 as a dumb switch and not even see it. With a mainline kernel and the B53 DSA driver you would be able to represent both switches in Device Tree and describe how they are cascading from each other. The potential Device Tree changes could look like this (based on your explanation, but I am not sure) for your platform, assuming the 53125 is actually exposing the front panel ports and that we did introduce a "mdio" node which would be required to expose the external BCM53125 switch. /* There is no MDIO node, there should be one */ &mdio { status = "okay"; switch@30 { #address-cells = <1>; #size-cells = <0>; reset-gpios = <&gpio 10>; reset-names = "robo_reset"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "lan1"; }; port@1 { reg = <1>; label = "lan2"; }; port@2 { reg = <2>; label = "lan3"; }; port@3 { reg = <3>; label = "lan1"; }; port@4 { reg = <4>; label = "wan"; }; port@5 { reg = <5>; label = "cpu"; ethernet = <&sw0port8>; fixed-link { speed = <1000>; full-duplex; }; }; }; }; }; &srab { status = "okay"; ports { #address-cells = <1>; #size-cells = <0>; port@5 { reg = <5>; label = "cpu"; ethernet = <&gmac0>; fixed-link { speed = <1000>; full-duplex; }; }; sw0port8: port@8 { reg = <8>; label = "extswitch"; fixed-link { speed = <1000>; full-duplex; }; }; }; }; > > Thanks, > > Vivek > > > On Wed, Mar 15, 2017 at 2:52 PM Andrew Lunn <andrew@lunn.ch > <mailto:andrew@lunn.ch>> wrote: > > Hi Vivek > > > - It has two switches in order to support 8 lan ports.

Thanks Florian. Let me try this out. First I'll try to figure out how to add a mdio node. Over the weekend I was trying enable DSA driver, but did not see DSA under network. I'm using LEDE source with kernel 4.9. Nor did I see it when I tried 'make kernel_menuconfig' Thanks again.

However, I only get packets flowing only through the internal switch. I have used the ip & bridge commands to setup the vlan 101 & 102 for lan and wan respectively. VLAN101 = lan1 lan2 lan3 lan4 lan5 lan6 lan7 lan8 eth0.101 VLAN102 = wan eth0.102 Reading configs from the factory firmware, I'm sure that sw0port0 and sw1port8 are connected.

So here are a few things that you want to check: - read the MIB counters from the "extswitch" interface and see if packets flow through in both directions with no errors - check the "extswitch" VLAN configuration on both the internal switch side (port 0) and on the external switch side ("cpu", port 8, not visible) - see if you can get traffic end-to-end from eth0 all the way through one of the external switch port. If that's the case, that means that the configuration of internal switch port 0, internal switch CPU port, and external switch external port is working and operational [1]: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e47112d9d6009bf6b7438cedc0270316d6b0370d > VLAN102 = wan eth0.102 > > Reading configs from the factory firmware, I'm sure that sw0port0 and> sw1port8 are connected.

If 0 is internal switch identifier and 1 is the external switch identifier, your mapping looks correct to me with one exception below: > cpu_port_number=5 7 8 > cpu_port_switch_id=0 0 0 > hidden_port_numbers=0 8 > hidden_port_switch_id=0 1 > > Below is my updated device tree. > > Thanks, > > Vivek > > &srab { > compatible = "brcm,bcm53012-srab", "brcm,bcm5301x-srab"; > status = "okay"; > dsa,member = <0 0>; > > ports { > #address-cells = <1>; > #size-cells = <0>; > > port@1 { > reg = <1>; > label = "lan7"; > }; > > port@2 { > reg = <2>; > label = "lan4"; > }; > > port@3 { > reg = <3>; > label = "lan8"; > }; > > port@4 { > reg = <4>; > label = "wan"; > }; > > port@5 { > reg = <5>; > ethernet = <&gmac0>; > label = "cpu"; > > fixed-link { > > speed = <1000>; > full-duplex; > }; > }; I think this is meant to be port 8 here based on the hidden_port_number value. This actually matters for VLAN configuration because B53 is not (unfortunately, to be fixed) consistently using dst->cpu_port (whatever is configured in Device Tree) vs. dev->cpu_port (hardcoded to 8 for this class of switch). PS: on that front, we will have to rework that when we bring multiple CPU port support in DSA/B53/bcm_sf2 and so for now what we could do is just check that the configured CPU port in Device Tree is a valid CPU port for that switch (typically 5, 7 or 8), and if not, just issue a warning. > > sw0port0: port@0 { > reg = <0>; > label = "extswitch"; > > fixed-link { > speed = <1000>; > full-duplex; > }; There might be some additional configuration needed here for this port, because by default, the port will most likely try to use its built-in PHY and maybe that's what they did, they wired the built-in PHY directly to the IMP port of the external switch. > }; > }; > }; > > &mdiomux { > mdio-slave@0 { > reg = <0x00>; > address-cells = <1>; > size-cells = <0>; > > switch@0 { > compatible = "brcm,bcm53125"; > #address-cells = <1>; > #size-cells = <0>; > reset-gpios = <&chipcommon 10 GPIO_ACTIVE_LOW>; > reset-names = "robo_reset"; > reg = <0>; > dsa,member = <1 0>; > > ports { > #address-cells = <1>; > #size-cells = <0>; > > port@0 { > reg = <0>; > label = "lan1"; > }; > > port@1 { > reg = <1>; > label = "lan5"; > }; > > port@2 { > reg = <2>; > label = "lan2"; > }; > > port@3 { > reg = <3>; > label = "lan6"; > }; > > port@4 { > reg = <4>; > label = "lan3"; > }; > > sw1port8:port@8 { > reg = <8>; > ethernet = <&sw0port0>; > label = "cpu"; > phy-mode = "rgmii-txid"; > > fixed-link { > speed = <1000>; > full-duplex; > }; > }; > }; > }; > }; > }; >

Given that I see RxFCSErrors and RxSymbolErrors errors wrt extswitch. configuration definitely needs tweaking. I tried setting the phy-mode to rgmii and rgmii-txid but no go. Thanks, Vivek

Configuration may have to be tuned on both switches unfortunately because both RGMII interfaces would have the ability to configure delays. Do you have a way to dump what the original firmware settings for the register that b53_adjust_link() modifies such that we can see what was previous configured? Thanks!

It appears that I do not need to set any phy-mode on internal sw's port 0 or external sw's port 8. Also, you were right about internal port 0 to be configured as tagged member of the vlan. It was indeed set to untagged! LEDE lacks aw way to configure this. But I can do this via a post script. After making above changes I was able to ping the router using physical port on external switch. However, the ping dies out after few seconds. I'm try to figure out the cause for this.

Hardware Info ------------- Processor - Broadcom BCM4709C0KFEBG dual-core @ 1.4 GHz Switch - BCM53012 in BCM4709C0KFEBG & external BCM53125 DDR3 RAM - 256 MB Flash - 128 MB (Toshiba TC58BVG0S3HTA00) 2.4GHz - BCM4366 4×4 2.4/5G single chip 802.11ac SoC Power Amp - Skyworks SE2623L 2.4 GHz power amp (x4) 5GHz x 2 - BCM4366 4×4 2.4/5G single chip 802.11ac SoC Power Amp - PLX Technology PEX8603 3-lane, 3-port PCIe switch Ports - 8 Ports, 1 WAN Ports Antennas - 8 Antennas Serial Port - @J6 [GND,TX,RX] (VCC NC) 115200 8n1 I was able to test this with Lede with following quirks. - Broadcom 4366c0 wireless chip is used and it's firmware package doesn't exist yet. I was able to test it with firmware that came buried in the router's dhd.ko - CPU is connected to port 5 - It has two switches in order to support 8 lan ports. Internal switch is BCM53012. The external switch BCM53125 currently works as "dumb switch" - Using 8 bit ECC gives errors, switching to 1 bit ECC solved the issue - It uses dual firmware (trx) copies for failsafe purposes. Installation ------------ Linksys gpg-signs their firmware for this router, hence it is not possible to install using Factory UI. This router needs serial cable hooked up to J6. Then interrupt the boot process by Ctrl+C to enter CFE prompt From there execute: `flash -noheader 192.168.1.10:/lede.trx nflash0.trx` where 192.168.1.10 is where your tftp server should is running. You may want to reset partial boots using `nvram set partialboot=0 && nvram commit' while at CFE prompt. TODO ---- - Add BCM53125 (secondary switch) to dts - Add robo_reset gpio (pin# 10 active low) to dts Signed-off-by: Vivek Unune <npcomplete13@gmail.com> --- arch/arm/boot/dts/bcm47094-linksys-panamera.dts | 97 ++++++++++++++++++++++++- 1 file changed, 96 insertions(+), 1 deletion(-)
