Hi,

I put U-Boot for the Colombus on an SD Card but could not make Ethernet work.

In U-Boot v2015.10, v2016.01 and v2016.05, Ethernet port is not detected. In U-Boot v2016.03, the Ethernet port is detected but cannot be used. I get the following error:

To be a Bit more precise, we've been (obviously) using the Colombus_defconfig configuration.

In the former case, the ethernet device doesn't even get registered apparently (while it does on the hummingbird, which is kind of weird).

In the latter, we get:

=> dhcp ethernet@01c30000 Waiting for PHY auto negotiation to complete......... TIMEOUT ! ethernet@01c30000: No link.

Which seems to be that the PHY isn't powered up. We looked at the schematics, and there's nothing really standing out. Chen-Yu also suggested to poke the PA21 pin that is usually used for PHY reset, but it didn't really change anything.

I think you had a Colombus Hans, have you tested it lately? Was it working out of the box for you, or is there some GPIO that needs to be poked somewhere?

Thanks, Maxime
