T2081: Enabling MAC10 for 1G speed in u-boot level

[noufalp90]

Hi All,

In my design, we have 1G ethernet connected to Processor side.(T2081). I want to enable MAC10 interface instead of MAC4 for RGMII connection. Can anyone help me to bring up MAC10 interface with RGMII in u-boot level

Thanks,

dear @noufalp90,

you have to set some fields into the RCW, please review the chapter "3.4.11 Ethernet controller 2 and GPIO3 signal multiplexing" to get the whole details.

Hi,

Anyone can guide me how can I enable the Mac10 in u-boot level for T208x ??

In my project, we are able to see linkup for only 100Mbps. But as per errata "A-009057: MAC4 does not support 10/100Mbps operation when connected to the RGMII interface", it is mentioned that MAC4 does not support 10/100mbps, only MAC3 and MAC10 is supported. So I would like to configure either MAC3 or MAC10 as default ethernet for us.
