I'm using same modules but one ethernet only, so I cant help so much. But as gmac is compatible with emac I think you should try EMAC on port H to test a board layout/phy that you know is ok.
I think Awsom EVB do not have differential pairs on gpio-3, so maybe you have a hardware issue. cheers, - Roberto But I think you should try to put EMAC on On Tue, Nov 11, 2014 at 2:55 AM, <[email protected]> wrote: > I have A20-SOM-EVB, but i need 2 ethernets.

Emac when trying pings send broken packets like: > 6f:73:fe:96:6f:73:fe:96:6f:73:fe:96:6f:73:fe:96:6f:73:fe:96:6f:73:fe:96:6f:73:fe:96:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 > Sorry for my english. > Anybody run 2 ethernets on A20? > > DTS: > /dts-v1/; > > / { > - Roberto -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
