TDA2EVM5777: Linux - eth0 device not found

Part Number: TDA2EVM5777

Hi.

I am trying to set up an NFS shared folder using TDA2EVM5777.

I'm working in a Linux environment, but the eth0 device doesn't appear.
I checked the eth0 device through the "ifconfig -a" and "ls -l /sys/class/net/" commands, but the eth0 device does not exist.

==================================================================================

lrwxrwxrwx 1 root root 0 May 13 19:52 sit0 -> ../../devices/virtual/net/sit0

==================================================================================

However, I have confirmed that the network operates with the Ping command in U-Boot.
(I have set up ipaddr, gatewayip, netmask with the setenv command.)


So, there seems to be a problem with Linux settings.

How can I find the eth0 device on Linux?

In addition, I would like to modify the VisionSDK App and build it to update to the NFS shared folder.
Do I simply change the app.out file? Or do I need more work to do?

Regards,

Lee.

    Hi Lee,

    Based on the information you have provided it looks like probe of Ethernet device failed during linux boot.

    Can you please share linux boot logs and the dts file you are using?

    Thank you

    Regards

    Hi Santhana Bharathi,

    Attach my Linux boot log and dts files.

    I resolved this issue.

    It was a problem with the settings in my dts file.
    (ti_components/os_tools/linux/kernel/omap/arch/arm/boot/dts/dra7-evm.dts)

    The mac setting was "disabled", and after changing to "okay", the eth0 device is output normally.
