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?
