Ethernet port #1 (ETH1) - J9[edit | edit source]
J9 is a RJ45 Gigabit Ethernet connector - incorporating magnetics - connected to Micrel KSZ9031 PHY (Gigabit Ethernet Transceiver). This, in turn, is connected to PL's bank 34 via RGMII interface. This is an example of EMIO routing showing how to route PS's MAC signals via PL subsystem. Please note that, in case PL is not properly configured, this second Ethernet port will not work.
