Re: [microblaze-uclinux] Problem with Ethernet: I can't ping

First try was to plug the Dev board on our Wifi router, but we cannot select speed and duplex on it so 100Mbps ... it's automatical I don't know why when the network adaptater (or router) is in auto-select mode it chooses 100Mbps.

Have you tried using a hub in order to make sure that its just not the cross over cable. I have found that when i have problems with cross over cables especially in host and target network configurations that using a switch or hub fixes most problems. Lance

    Hi everyone,

    I've followed the instructions from John Williams and Jason Wu, and
    finally got uClinux-kernel booted on my Spartan-3E-Starter-Kit
    (
    http://www.xilinx.com/xlnx/xebiz/designResources/ip_product_details.j...).


    However, there's no boot message on the terminal, I got just a login
    prompt when the kernel started:
    uclinux-auto login:

    Anyway, the kernel still works.
    Then I tried to test the networking and followed the instructions.

    There's no problem to ping itself. But I can't ping my PC, which is
    connected to the Eva-Board using crossover cable. There's even no ARP
    packets received.
    It seems that the RX- and TX-pins are not connected to the FPGA.
    Did I
    miss something?

    Any help is appreciated.

    Qichen
