Linux/AM3352: Dual Ethernet, swap eth0, BRCM switch interface...

newuser

Part Number: AM3352

Tool/software: Linux

Hello,

On my board I have connected MII_1 to BRCM switch and RGMII_2 is connected to TI PHY. I have already verified at u-boot level, at a given time either MII_1 with BRCM switch works OR RGMII_2 with TI phy is working – so there is no hardware or connection issue.

I am having hard time to make network working at Linux level. My requirement are as follows.

RGMII_2 (TI-PHY) will connect to outside world to external router and gets IP address from external DHCP server/router. I would like this interface to be come up as "eth0".
MII_1 – BRCM switch, I will be running DHCP server locally on AM3352 – so when external device is connected to this 4 ports of BRCM switch, it can get IP address from this locally running DHCP server. (e.g. 30.30.30.1, 2,3,4. gw=30.30.30.100).

I would like “eth0” to be assigned to RGMII_2, “eth2” will be assigned to MII_1 – how to do that? Normally by default “eth0” is assigned to MAC1.

Does BRCM switch will get its “ethX” interface? I am not sure? How it works – I am working on this kind of configuration first time so really don’t know how it works?

I would like to know what kind of changes I have to do in Linux so above configuration can work. At Linux – how to program BRCM 53101 ethernet switch?

For your reference I am attaching my Linux – defconfig file, and DTS files.

Any help is truly appreciated.

New user….

RGMII_2 is connected DP83867.

MII_1 is connected to Broadcom 53101 (manage switch mode configuration).

Hi,

The swapping of the CPSW external ports is not something that the driver supports so I will not be able to support what you are asking for assistance with.

This question has been asked before though on the TI e2e forum and there may be other possible solutions found. This link might be a start to a solution but you will have to develop the solution and decide if it meets your requirements.

Link swapping ports due to board silk screen labeling

Again I need to point out the suggestion in the link above is something at the user layer which is higher up in the network stack that TI does not support.

Best Regards,

Schuyler

Hello Schuyler,

OK, that is fine with me - so we will keep swapping of port aside.

I want to know how to make my eth0 and eth1 working? Any help is really appreciated.

MAC1 - goes to BRCM ethernet switch,

MAC2 - goes to TI PHY.

I have already attached my defconfig and dts file. If I get any help on that front will be very useful.

we will keep swapping of Ethernet port aside, but I want my MAC1 - which goes to BRCM switch and MAC2 - goes to TI PHY is not working. any help on that...

Hi,

For our internal metrics I will split the thread since this thread has been about swapping the CPSW Ethernet interfaces.

Best Regards,
Schuyler

Hi,

I have split into these threads:

- Interfacing the CPSW to an external switch

- Interfacing the CPSW 2nd port to a TI PHY

As for this thread I will mark it closed for now as the swapping of ethernet ports is not supporting in the current CPSW driver.

Best Regards,

Schuyler
