Hello
on my custom AM3352 based board i have 2 PHY ethernet that are well recognized.
If i validate only one slave PHY (by changing the @ of second PHY on mdio in devices.c) , all is working fine (DHCP, NFS...)
But if i validate the 2 PHY, it seems there are both linked to eth0 and NFS isn't working any more.
Should one PHY be connected to eth0 and the other eth1 ? How can it be done ?
Thanks for any help
best regards
