Re: [ECOS] SIOCIFADDR: Device not configured

[sebastien Couret <sebastien dot couret at elios-informatique dot fr>]

Hello,

If U have a close look at your traces , you will see that MAC address 
attributed to eth0 is bad : 'hw_addr: ff:ff:ff:ff:ff:ff.'
This happens often when the ethernet driver return -1 to show an error.
I can't figure the real cause of this error, but may be you should answer 
these questions :

Have U already connected something to this plug ? is the link up and running ?
(Some drivers must be run with the plug connected )

May be you should try to test your ethernet connectivity just with redboot 
running (without your application) (redboot can be configured by fconfig 
command) 

Or you can also try to had debugging information to your application.
(have a look in I/O sub-system) with config-tool

For information, SIOCIFADDR is an ioctl call to change/set the IP adress.

Hope this help.
