    So I'm trying to get CAN going on UDOO NEO - and yes, I'm aware of the posts about it and I'm working on following those, but I'm stuck trying to get uboot to use the correct .dtb file, but it doesn't work for me.

    Seems to be not using the correct .dtb file on boot.

    My board uses this one:

    reading dts-overlay/imx6sx-udoo-neo-full-hdmi-m4.dtb

    This is my latest uEnv.txt:

    video_output=hdmi
    #m4_enabled=false
    #m4last=/path/to/arduino/sketch.fw
    fdt_file=imx6sx-udoo-neo-full-hdmi-can.dtb
    use_custom_dtb=true

    I've tried this:

    fdt_file=dts-overlay/imx6sx-udoo-neo-full-hdmi-can.dtb

    But it always still uses the same dtb file:

    reading dts-overlay/imx6sx-udoo-neo-full-hdmi-m4.dtb

    How can I make uboot read the proper dtb file? I don't find any examples of uEnv.txt and uboot, etc. so I don't know if what I am doing is even correct.

    Thanks,
    Randy Krakora
