Linux/TMDXEVM8148: Ethernet application button disabled in EZSDK Matrix application

Part Number: TMDXEVM8148

Tool/software: Linux

Hello folks,

Recently i purchased a TMDXEVM8148 board. I loaded the SD card which came with the box and booted the board.

I was able to see the matrix application being loaded onto the LCD. In this , the Ethernet button is shaded out and on pressing i see a button "coming soon". I dont understand why the Ethernet button is faded out ?

I have connected the Ethernet to this board from a router. The LED's in the RJ45 connector glows. Even i tried setting static IP through minicom console. But Ethernet button is faded out. Can someone help me on this?

Also the Qt based Browser application in this matrix application doesnt connect to the internet. I tried clicking some of the Qt related website pinned on this browser application, but still it doesnt connect to the internet.

What am i missing here? I read the SW developers guide doc, but it says nothing about this.

    Hi Arunkumar,

    Very often the SD card that come with the EVM is not flashed with the latest DM814x EZSDK 5.05.02.00:

    Could you please re-flash your SD card with the latest EZSDK 5.05.02.00?

    If the Matrix ethernet feature is missing there also, then you should try to integrate that feature from AM335x SDK6 (matrix-gui-2.0) to DM814x EZSDK (matrix-gui-1.3)

    Hi Pavel,

    Thanks for your kind response and sorry for the late reply. As suggested, i tried flashing the SD card with the latest SDK and loaded the SD card onto the EVM.
    Now the Ethernet was up and DHCP was able to get the IP. I was able to ping the EVM from host machine.

    All these are from the minicom console. However after the Matrix application, the ethernet button is still disabled. Looks like i have to integrate from AM335x SDK or to debug it.

    Also i would like to perform the below steps. Can you please share some pointers.

    The Software dev guide speaks about setting up the board for booting from using TFTP and NFS. It says "To boot the board from NFS, you may need to change the boot switch settings on your EVM". When i referred to TI81XX_PSP_U-Boot.pdf, There is no switch setting to set up this. What steps should i do for following this procedure?

    Boot mode EMAC is what you need.
