Thanks @morsucci, Some kind of reference like this was what I was looking for. This will keep me busy for sometime.

Hi @jpeyron, I don't mind accessing the Pmod NIC100 directly through the SPI interfaces available for the ARM processors on the Zynq chip rather than going through the FPGA. So I assume that I would not need an IP core for SPI and enc424j600. I have enabled (as lkm) the encx24j600 driver available in the zynq linux kernel. Now that I have the following device tree for SPI1, I need to know what to add inside this tree to bind the encx24j600 driver to the enc424j600 chip on the Pmod NIC100: spi1: spi@e0007000 { compatible = "xlnx,zynq-spi-r1p6"; reg = <0xe0007000 0x1000>; status = "disabled"; interrupt-parent = <&intc>; interrupts = <0 49 4>; clocks = <&clkc 26>, <&clkc 35>; clock-names = "ref_clk", "pclk"; #address-cells = <1>; #size-cells = <0>; }; Let me also know if there is a different way to bind the encx24j600 driver to the Pmod NIC100 chip over SPI1 interface.

Hi Guys, My application on linux requires two ethernet ports on the Zybo Z7 board. So I have recently bought a Pmod NIC100 card. I read the references and I have enabled the encx24j600 driver in the xilinx linux kernel. I have enabled SPI0 controller in vivado for the Z7 board. Correct me if I am wrong, but I reckon to use the enabled encx24j600 driver, I have to add the interrupts and registers under spi parent in the device tree but I don't know the specifics of what I have to add. Can someone please help me out? My intention is to get this board to appear as eth1 in xilinx linux. I would appreciate any other way than device tree method to do this as well. Let me know if you need any other information.
