AM5728: Ethernet issue

kishan patel14
Genius 3250 points
Part Number: AM5728

Hello,

          I am using "ti-processor-sdk-linux-am57xx-evm-04.02.00.09" SDK on AM5728 EVM board.

I have connected ether-net cable on board and i can also check IP-ADDRESS but i could not access Internet or ping to any site.

Any configuration required for Internet?

Thanks and Regards,

Kishan Patel.

    Hi,

    There is not any configuration necessary, network connectivity should work out of the box. The AM5728 evm has a stack ethernet connector. eth0 is the bottom port, eth1 is the top port. Which port are you plugged into? Also please attach the results of ethtool eth0 and ethtool eth1 and ifconfig.

    Best Regards,
    Schuyler

    Hi,

    I apologize believe I misunderstood your original post. I thought you were having trouble getting an ip address on your local network.

    TI is not able to support local network to internet setup as there are several steps that are needed in configuring access such as including firewalls and proxies needed for accessing the internet inside a corporate environment. I have assumed here that is your current environment.

    Currently the only suggestion I can offer is to look at examples of setting up proxies for a userspace that uses systemD for network management. I am assuming here that you are using the file system with the TI SDK which uses systemD for user space setup.

    Best Regards,
    Schuyler

    Hello Schuyler,

               Ohk.

               So, do you know require configuration to access internet?

    Thanks and Regards,

    Hi,

    Per what I was mentioning in the previous post this is something unfortunately TI cannot support. There is network management configuration required to access the internet especially if behind a corporate firewall. These configurations will be unique to your local network. This is not a low level driver issue but a higher level network access issue that will involve setting up proxies and resolving DNS sources. You be should be able to look for systemD examples that can show you how to configure your system. Also to my understanding ICMP messages (pings) do not cross proxies servers.

    Regards,
    Schuyler

    Hello,

              Actually i have no idea about what you are saying.

    I just want to clarify one thing here is that we have not set-up any wirefall in network.

    All system can easily access the Internet by connect the LAN.

    Thanks and Regards,

    Kishan Patel.

    Hi,

    Essentially explaining it another way is that TI only supports Ethernet driver support and it's connection to a local subnet. TI does not test the SDK and drivers beyond this network topology. That is OK if your setup does not use a firewall because that could relieve the proxy issue but as per the previous post TI does not support configuring the files necessary such as defining the source of the DNS server to access through a gateway.

    The file system that ships with the SDK is using SystemD for network management. We don't have any examples we can offer on configuration so the only suggestion I can offer is to look at SystemD configuration examples for setting internet access.

    Schuyler

    I have done following steps to get access internet and ping system using DNS(ping google.com):

    >execute command: "vi /etc/resolv.conf"
    >now enter follow details and save file

    nameserver 8.8.8.8
    nameserver 127.0.1.1
    nameserver 8.8.4.4
