Part Number: AM3359
Hello all,
We are working on a custom board based on AM3359 ICE V2.We have 3 phys connected,two DP83867s and one MAX24288.One DP83867 is connected to rgmii1 and the MAX and other DP83867 is connected to rgmii2.We intend to use only two of these at a time.But after booting DP83867 connected to rgmii is detected as GENERIC PHY and TI DP83867 is not being attached the phy.What could be the reason?
