Re: [microblaze-uclinux] lltemac

["Tommy Kamps" <tommy.kamps@xxxxxxxxx>]

Hi guys,

I have exectly the same problem as described below. Has a solution
already been found?
I have successfully applied the patches (with some manual intervention
in the makefile) and was able to build without any problems.
When I try to boot the kernel I also receive the following messages:

Setting up interface eth0:
SIOCSIFADDR: No such device
eth0: unknown interface: No such device

Thanks in advance.

Regards,

Tommy Kamps
