Part Number: DRA821U
Other Parts Discussed in Thread: DRA821

Tool/software:

Hi, 

    my working environment is as follows:

        1. SDK: j7200-evm-10_00_07_03

        2. boot mode:sbl + linux with sdcard

       3. board: custom board

   Now, we want to config thernet, please provide detail gudie to help us enabl linux native ethernet for our customer board.

   And, we have consulted DRA821U: How to enable CPSw5g linux native ethernet for SGMII, RMII on DRA821, but still do not know which files to configure. Because our boot cannot boot from uboot, Please give some detail guide.

   Thanks.

    Best regards!

    Hi,

    Please refer to FAQ for enabling Native Linux Driver for CPSW5G in J7200(DRA821).

    Hi, 

    Our boot mode is mmcsd, and bootloader is SBL, not SPL. The FAQ you provided requires the use of uEnv.txt, but SBL does not use this file. In addition, the FAQ guidance provided says k3-j7200-evm-virt-mac-client.dtbo, but this file is nowhere to be found in SDK10.0. So how should we read our documents?

    hello Charles

         SBL   image is needed to be rename to tiboot3.bin and copy to the BOOT partition of the SD card, and linux kernel is needed to be compiled into the combined image, and rename it to "app", then you can run SBL to boot up the sd card

         please refer to following link to compile combined image:

    In case of SBL boot without u-boot then you need to integrate the device tree overlay into device tree files and rebuild the device tree and use the updated binary.

    Also, for Native Linux Driver you can ipc echo test binary to MCU2_0 while preparing combined app image or soft-link in /lib/firmware to boot from Linux.

    k3-j7200-evm-virt-mac-client.dtbo is changed to k3-j7200-evm-ethfw.dtbo.
