Hi,
I have some problems with PICOMOD7A ax88796 ethernet controller. We have one site installation where PICOMOD7A connected to site router shows these messages:
[ 37.734816] PHY: ax88796-0:10 - Link is Down
[ 39.749825] PHY: ax88796-0:10 - Link is Up - 100/Full

[ 77.864861] PHY: ax88796-0:10 - Link is Down
After a certain period of time, retries cease and, of course, ethernet communications are impossible.
We have tried various boards to test if ti's a matter of a HW failure, but it is not. however, all tested boards connect correctly to a PC with direct crossed cable o in our corporate network.
Also, comms are running OK against the mentioned router with another ethernet link we have installed in our board (a DAVICOM DM9010 industrial type) connected to FS expansion bus.
Any idea of what can be happenning?
Best regards,
