eth1 not working, Linux 4.1.15

    Using the last 4.1.15 kernel from F+S, eth1 does not work. eth0 works properly.
    May be related to some DTS Hardware binding issues for eth1 ?

    Dear Mr. Euzenot,


    which release version do you use?
    Can you post or append your devicetree?

    The dtb file is the one provided in f+s software package (sdcard-fsimx6ul-V2.0.tar.bz2) unchanged. Same for the kernel and the rootfs.
    Attached the dtb file.

    Okay do you use the same U-Boot which is in the package sdcard-fsimx6ul-V2.0.tar.bz2?
    Which U-Boot version do you have?
    Normally you should have this U-Boot.

    I have just updated u-boot: problem persists and
    now eth1 becomes always a random mac address in Linux.
    Do I need some additional U-boot environment variables maybe ?

    You have to set the two variables ethaddr and eth1addr to the correct network addresses.


    Code
    1. setenv ethaddr 00:05:51:xx:yy:zz
    2. setenv eth1addr 00:05:51:xx:yy:zz+1
    3. saveenv


    The three final hex digits xx yy zz are given on the barcode sticker on your board. The address for the second port is one higher than for the first port.


    Unfortunately, U-Boot also only detects one ethernet. Are you sure that you have two PHYs equipped on the board? Is the barcode sticker white or yellow?

    A white sticker indicates a single ethernet port. So I assume the board is only equipped with one ethernet port. The PHYs are on the bottom side of the efusA7UL module next to each other. You can easily see if there is one PHY missing or not.
