Part Number: J7200XSOMXEVM
Other Parts Discussed in Thread: DRA821

Hi All,

This is regarding DRA821 Board Ethernet Communication.

I have J721EXCP01EVM with J7200XSOM Boards, we have connected the J721EXCP01EVM board to the ethernet router switch and the board  is connected to testing system with debugger cable.But we are not able to detect the ip address of the board.

Can you please suggest us if we need to make any specific connection or settings on board to enable ethernet?

Thanks and Regards,

Saba

    Saba, 

    I assume you are using the Linux SDK 8.02. There are total of 5 Ethernet ports. One is one the main board that is the MCU_CPSW, and another 4 are off the QSGMII daughter card. 

    Which port did you connected to the router? Note that:

    MCU_CPSW should work out of box using DHCP with no issues

    CPSW5G ports is using EthFw by default, these ports should also work out of box. But you may want to double check your u-boot params are set to bring the PHY device on the QSGMII daughter card out of reset. You should see LED lights up on the QSGMII Ethernet jacks. Otherwise, you can try the following command :

        run init_main_cpsw0_qsgmii_phy

    on u-boot prompt, then boot Linux. Alternatively, you can stop uboot and issue

    • setenv dorprocboot 1
    • saveenv 

    then power cycle the board.
