Hi I have a problem, I have been tring to configure the EMAC for the
Hawkboard, is is based on board -da850-evm.c but I can't make it
works. The files system boots but give me this error
Setting up IP spoofing protection: rp_filter.
Configuring network interfaces... ifconfig: SIOCGIFFLAGS: No such device
done.
hwclock: can't open '/dev/misc/rtc': No such file or directory

hwclock: can't open '/dev/misc/rtc': No such file or directory
INIT: Entering runlevel: 5
Starting telnet daemon.
Starting syslogd/klogd: done
when i do the ifconfig
r...@hawkboard:~# ifconfig
lo Link encap:Local Loopback

So the EMAC is not working
The code ( patch ) is the next:
#include <mach/mux.h>
