    Hi,

    I want to netboot my udoo-neo but when trying I get:
    Net: CPU Net Initialization Failed
    No ethernet found.

    Am I the only one having this?
    Is this a known problem?

    Dear Luc,
    sorry, we haven't tested netboot yet. Is there some information we can give you to help you test it?

    Hi Andrea,

    I'm not sure ;)
    I've seen that the network options are not defined in include/configs/udoo_neo.h
    But even after having enabled them, recompiled the u-boot image and installed it on a SD card
    it still not working, giving the following message on the console:
    Net: Phy not found
    PHY reset timed out
    FEC0

    A ping take a long time (10 seconds) and then fail:
    => env set ipaddr 192.168.1.31
    => ping 192.168.1.1
    Using FEC0 device
    ping failed; host 192.168.1.1 is not alive

    So yes, I would guess that there is something with the PHY (is it the same as the dual or quad?)

    Luc

    Hi there Luc,
    no, it's not the same. The code of PHY is different.
    The PHY's code of Neo is KSZ8091RNAIA
    Sorry if I don't have so much information, but I'm not practical on this. For every information you need do not hesitate to ask.
    I don't know if this is the same PHY used on i.MX 6 SoloX Sabreboard.
    However, here is Neo's schematics, I think you were looking for them.

    Yes, netboot(tftpboot and nfs) works fine on my UDOO Neo Full.
    See attached log files.
