Re: [ECOS] Problems initializing eth0 interface

[Bruno Ricci <amraam83 at gmail dot com>]

Hi again,

I tried the same configuration with RTL8139 chip and without removing
any package (I managed to have a pc with that chip) with no luck. Here
some screenshots:

Notice that my program only initializes the network card, and that
there's a 20 sec sleep between the two screenshots. I tried to set a
static IP, but I keep on having that SIOCIFADDR error.

Thanks again for support

Bruno
