I am planning on using both RGMII ports on the AM3359_ZCZ and I have a question on where I should connect the GMII2_REFCLK. I am using pin H16 for the GMII1_COL. I am trying to interface to a Micrel KSZ9021RN PHY Hello James, ...

calledaxi_ethernet_0_refclk. This block generates a 125MHz and 200MHz clock to feed the Ethernet blocks, however we will be using the Zynq PS to generate those clocks, so we don’t need this block. Click once on theaxi_ethernet_0_refclkblock and press Delete to remove i...
