    Ethernet for Zybo Linux

    Sorry for the late answer. I got my ethernet running now. I think my Yocto image was the key of the problem. With the Xilinx ramdisk example, the ethernet works well, so I create a new Yocto image today and now my ethernet works very with my new SD-Card image. Thank you for help. If someone else needs a working image for the Zybo, please check my git project https://github.com/Kampi/Zybo-Linux There you will find all the necessary files.

    Ethernet for Zybo Linux

    Hello, could this problem have something to do with missing ip tables?

    Ethernet for Zybo Linux

    Hello, yes I think I have to test it with wireshark (will do it this week). The connection between Switch and PC works, because I have my raspberry pi connected with that switch and I can ping it (maybe I use an uplink port of that switch? Just an idea, i,ve got in this moment).

    Ethernet for Zybo Linux

    Hello, thank you. The ethernet interface is working now, but I can´t ping the zybo from my PC. IP-address etc. should be ok, because I can ping another device if I plug the LAN-cable from the zybo into another device. Is there anything else which can do "problems" and block my ping?

    Great. This solution works. Now I have an ethernet device. But why is this working?

    Ethernet for Zybo Linux

    Hello, thank you for your answer. Please take a look at "Ethernet.png" for my ethernet settings. I use the same as in this thread. But I don´t have any ethernet interface when I use the "ip link show" command after booting linux. root@linaro-developer:~# ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1 link/sit 0.0.0.0 brd 0.0.0.0 root@linaro-developer:~# Should I make that MDIO-Port external?

    Ethernet for Zybo Linux

    Hello, my ethernet for my Zybo doesn´t work with Linux. I use this linaro as my rootfs. Additional I follow these instructions to create my Design with all necessary files. My Linux boots up, but I got the message "no phy found". I´ve update my device tree with this: ZyboEthernet.dtsi &gem0 { #address-cells = <1>; #size-cells = <0>; clock-names = "ref_clk", "aper_clk"; clocks = <&clkc 13>, <&clkc 30>; compatible = "cdns,zynq-gem", "cdns,gem"; interrupt-parent = <&intc>; interrupts = <0 22 4>; local-mac-address = [00 0a 35 00 00 00]; phy-handle = <&phy0>; phy-mode = "rgmii-id"; status = "okay"; reg = <0xe000b000 0x1000>; xlnx,eth-mode = <0x1>; xlnx,has-mdio = <0x1>; xlnx,ptp-enet-clock = <111111115>; mdio { #address-cells = <1>; #size-cells = <0>; phy0: phy@1 { compatible = "realtek,RTL8211E"; device_type = "ethernet-phy"; reg = <1>; }; }; }; Bootargs.dts /include/ "system-top.dts" /include/ "ZyboEthernet.dtsi" / { chosen { bootargs = "console=ttyPS0,115200n8 consoleblank=0 root=/dev/mmcblk0p2 rw rootwait earlyprintk"; linux,stdout-path = "&uart1"; }; }; How can I get my ethernet running? Thank you for help!

    Audio with PmodI2S with ZYBO

    Hello, thanks for your reply. I don´t have self powered speakers, so I have to buy some :(.... I think I could use . The PMOD-AMP3 looks like a good alternative, but it has I²C for configuration and I want to test I²S alone and without I²C configuration. Otherwise I could choose the audio codec on my ZYBO (which will be the next step after I²S is running).
