Re: [U-Boot] MAC address being reset to 00:00:00:00:00:00 ?

17 Feb 2009


      Hi!
Thanks. This solved the issue. I tracked this down and found that I was using an address that is a multi-cast address and it got rejected.
Now I wonder why the address isn't being set by U-boot? Any ideas?
Thanks,

Hi,
Look at the linux git code the driver use this function to fill the mac
address of your net,
and so I think that somenthing fail here. Maybe is not valid? Try to
verify if it fails.
const void *of_get_mac_address(struct device_node *np)
{
        struct property *pp;
    pp = of_find_property(np, "mac-address", NULL);
    if (pp && (pp->length == 6) && is_valid_ether_addr(pp->value))
            return pp->value;

    pp = of_find_property(np, "local-mac-address", NULL);
    if (pp && (pp->length == 6) && is_valid_ether_addr(pp->value))
            return pp->value;

    pp = of_find_property(np, "address", NULL);
    if (pp && (pp->length == 6) && is_valid_ether_addr(pp->value))
            return pp->value;

    return NULL;

}
Michael
