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.
Cheers, Moritz
