I've been working with a buildroot-2009.02 environment that I built for
a TS-7400 board (uses a 2.4 kernel) quite successfully for several
months now. So far I've been configuring the board's network settings
manually using ifconfig and route.
Recently I tried to start using DHCP, but udhcpc is not happy about
something:
# ifconfig eth0 up
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:D0:69:40:7C:D6
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:51 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:39
# udhcpc -i eth0
udhcpc (v1.13.2) started
Sending discover...
udhcpc: sendto: Network is down
Sending discover...
udhcpc: sendto: Network is down
I've verified the network is actually up (all the lights are on). If I
configure an IP address manually it works fine, e.g.:
# ifconfig eth0 192.168.1.30 up
# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes
64 bytes from 192.168.1.1: seq=0 ttl=64 time=0.000 ms
64 bytes from 192.168.1.1: seq=1 ttl=64 time=0.000 ms
64 bytes from 192.168.1.1: seq=2 ttl=64 time=0.000 ms
--- 192.168.1.1 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.000/0.000/0.000 ms
What could I be missing?
Thanks
Tobias
