I have an Ethercat card there I choosed KSZ8081 as PHY, driver for Ethernet, datasheet with registers where not available for chip used in reference design BCM4251XA1KMLG and KSZ8081 is common so I expected it work.
It auto negotiate with others, ordinary computer, switch, other ethercat card but not other card with the same PHY KSZ8081. I could actually put ethercat cards with KSZ8081 closest to computer another ethercat card in between an ethercat card with KSZ8081 at the then and work counter say it is communication in between all three cards in the chain. Registers suggest aut negotiation work, ack is sent but link up never occur. Do anybody have any idea?
