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
