AM335x mii2 enumerate as eth0

Keith Mo

Hi,

I'm wondering what changes do I need to make to the board file and/or linux drivers to have MII2 be enumerated as eth0.

For example, I currently need to do:

am33xx_cpsw_init(AM33XX_CPSW_MODE_MII, NULL, "0:07");

in order to access the phy at MII2. But this results in both eth0 and eth1 being enumerated, with eth0 being a dummy, while eth1 is the working eth device.

Thanks!

Hi Keith,

I will forward your question to the SW experts. Please post what Linux version you are using.

Hello Keith,

I will point you some feature in dual standalone EMAC mode:

- If eth0 is up, then eth0 napi is used. eth1 napi is used when eth0 interface is down

I suggest you to see following guide - http://processors.wiki.ti.com/index.php/AM335x_CPSW_%28Ethernet%29_Driver%27s_Guide

Best regards,

Yanko

Hello,

Thanks for the quick response.

Sorry, should have provided this info. I'm using 3.2 that came with ti-sdk 6.
