Hello,

did anybody setup successfully setup a direct MAC connection using RGMII with a zynq ? For example to a switch.

The zynq_gem driver wants to probe for phy by itself. I already made a connection with very bad hacks in various files.

In linux such things are working with "fixed-link". Also the i.mx6 FEC driver (not using DM) can operate in direct-connection mode.

For linux I have a patch that I've meant to submit since quite a while that makes fixed-link work for the cadence gem. Maybe you can use that as a starting point. It definitely does work.

I'll submit the linux one eventually, feel free to comment or improve.

many thanks for this. Looks good - i'll try it on linux later.

For now i have to bring this stuff up in vxWorks first.

For U-Boot i have some bad hack running, as told. I will start a implementation for "fixed-link" resp. "fixed-phy" in u-boot. Maybe i can provide some patch for RFC during next week.

cheers, Hannes
