Ethernet on Colombus (sun6i-a31-colombus)

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:

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

Thank you,

Quentin

Hi,

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:

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

Hi,

Hi, I just tied with current master (which will be released as v2016.07 real soon now, and this works fine with master for me.
