I start from uboot without configuring the ethernet connection via kernelparameters (as uboot environment is fix).
If I try to setup eth0 for DHCP I fail
"ifconfig eth0 dynamic up" gives back with "ifconfig" everything, but no IP address.
[root@here ]# ifconfig eth0 dynamic up
eth0: link down
eth0: link up, 100Mbps, full-duplex, lpa 0xCDE1
[root@here]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:11:22:33:02:02
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 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:181 DMA chan:ff
Otherwise calling linux it with kernel parameters "ip=dhcp" it works fine.
So any idea what might go wrong there?
If I check with ps the process list, I can't see any dhcp related service. Is this the reason? How to start this?
Best regards
