Im upgrading my SDK to sdk6.0.7
But when i config dual mac, i used the 335x-evmsk.dts as reference, and configed the cpsw and emac in dts.
I cannot ping my pc or other network in my am335x filesystem.

Seems that the emac0 and emac1 has been inited ok. However, i cannot ping my pc. The ifconfig result:

There a difference in hardware between the demo board and my board. Rmii1 and rmii2 address are 1,0 instead of 0,1.So i changged the dts emac phy_id.
My pinmux of rmii is:

Any fault here?Thank you.
