Need to do ping between MAC-MAC with out phy through SGMII

ramakrishnakatt · ‎02-02-2015

We have two routers in same chassis. we need to test communication between 2 routers. we have 4 SGMII interfaces. 2 are connected between CPU-FPGA. Another SGMMI between two routers. currently we are using free scale processor T1040 and kernel 3.8.13. I have changed dts file as fallows. Once the system up on two machines I am trying to ping with eth2 (eth0 and eth1 are used by CPU-FPGA). But I am not getting any response. I am attaching 2 dts files,

Pass case:

fsl_mac: fsl_mac: FSL FMan MAC API based driver ()

fsl_mac ffb4e0000.ethernet: FMan MEMAC

fsl_mac ffb4e0000.ethernet: FMan MAC address: 00:22:bd:dd:e7:8a

fsl_mac ffb4e2000.ethernet: FMan MEMAC

fsl_mac ffb4e2000.ethernet: FMan MAC address: 00:04:9f:03:05:e5

fsl_mac ffb4e4000.ethernet: FMan MEMAC

fsl_mac ffb4e4000.ethernet: FMan MAC address: 00:00:04:9f:03:05

fsl_mac ffb4e6000.ethernet: FMan MEMAC

fsl_mac ffb4e6000.ethernet: FMan MAC address: 00:04:9f:03:05:e7

Fail case:

fsl_mac ffb4e0000.ethernet: of_get_mac_address(/soc@ffb000000/fman@400000/ethernet@e0000) failed

fsl_mac: probe of ffb4e0000.ethernet failed with error -22

fsl_mac ffb4e2000.ethernet: of_get_mac_address(/soc@ffb000000/fman@400000/ethernet@e2000) failed

fsl_mac: probe of ffb4e2000.ethernet failed with error -22

fsl_mac ffb4e4000.ethernet: of_get_mac_address(/soc@ffb000000/fman@400000/ethernet@e4000) failed

fsl_mac: probe of ffb4e4000.ethernet failed with error -22

fsl_mac ffb4e6000.ethernet: FMan MEMAC

fsl_mac ffb4e6000.ethernet: FMan MAC address: 00:04:9f:03:05:e7

fsl_dpa: FSL DPAA Ethernet driver ()

fsl_dpa ethernet.16: dev_get_drvdata(ffb4e0000.ethernet) failed

fsl_dpa: probe of ethernet.16 failed with error -22

fsl_dpa ethernet.17: dev_get_drvdata(ffb4e2000.ethernet) failed

fsl_dpa: probe of ethernet.17 failed with error -22

fsl_dpa ethernet.18: dev_get_drvdata(ffb4e4000.ethernet) failed

fsl_dpa: probe of ethernet.18 failed with error -22

fsl_dpa: fsl_dpa: Probed interface eth0

fsl_dpa_shared: FSL DPAA Shared Ethernet driver ()

fsl_dpa_proxy: FSL DPAA Proxy initialization driver ()

fsl_oh: FSL FMan Offline Parsing port driver ()

Other than dts file changes do I need to do changes in phy driver file to tweek eth2.

Hi,

From the working .dts file provided, it seems sg.m3 is on MDIO bus:

mdio0: mdio@fc000 {

phy_sgmii_2: ethernet-phy@03 {

reg = <0x03>;

};

So my question is about the hardware, does Serdes lane B routed to PHY or to chasis?

Have a great day,
Lunmin

after assigning ip address the link was up, but ping is failing. that is our requirement. as a said this one MAC-MAC

ramakrishnakatt · ‎02-05-2015

Please ignore earlier dts, Now i have modifed dts and made eth2 as fixed-link. it is coming up fine. I have pasted new dts at end.

Once the linux up if I use.

root@t1040rdb:/media/ram# ethtool eth2

Settings for eth2:

If I assign ip address

root@t1040rdb:/media/ram# ifconfig eth2 5.55.11.39

root@t1040rdb:/media/ram# route add default gw 5.55.0.1 eth2

route add default gw 5.55.0.1 eth2

ethtool eth2

ethtool eth2

netstat -rn

ping 5.55.11.34

Same process i am doing on other router but still ping failing between two routers

And you wrote:

"mdio0: mdio@fc000 {

phy_sgmii_2: ethernet-phy@03 {

reg = <0x03>;

}

This does not connected to PHY. It is connected to other RSP." ====> How? Please clarify to help understanding. Thanks.

lunminliang · ‎02-08-2015

So one router eth2 has ip 5. 55.11.39 and another is 5.55.11.34? What's eth3 dedicated for?

What's the interface of router to chassis? Can you please clarify this? Thanks.

ramakrishnakatt · ‎02-04-2015

Hi Lumin,

Thanks for your reply, we are using T1040 eval board dts file, because of that we have not done any clean up.

In the

phy_rgmii_0: ethernet-phy@01 {

reg = <0x01>;

};

This is for Marvell PHY.

as you asked

mdio0: mdio@fc000 {

phy_sgmii_2: ethernet-phy@03 {

reg = <0x03>;

}

This does not connected to PHY. It is connected to other RSP.

I have modified dts file in clean way. PFA. But with this dts also I am getting same error

fsl_mac ffb4e0000.ethernet: of_get_mac_address(/soc@ffb000000/fman@400000/ethernet@e0000) failed

fsl_mac ffb4e6000.ethernet: FMan MEMAC

AS i said earlier we have 4 SGMII ports 2 SGMII ports connected to CPU to FPGA. 1 SGMII connected between 2 routers

One more question, for the working.dts you provided, do you mean all those links are up, or you can ping from one router to another on eth2?

lunminliang · ‎02-05-2015

Hi,

You wrote "We have two routers in same chassis."

and

"mdio0: mdio@fc000 {

phy_sgmii_2: ethernet-phy@03 {

reg = <0x03>;

}

This does not connected to PHY. It is connected to other RSP.

"

Then what's the interface to other RSP? The interface on the chassis? Are you using two identical routers? which is based on T1040. Please provide more detail information. A graphic may be useful.

Regards

Lunmin

Hi,

Is this dts the one after you modified? "I have modified dts file in clean way".

Have a great day,

Lunmin

Hi,
