I'm trying to boot a Linux 2.6.17 kernel from U-Boot, and it appears that it's ignoring the bootargs variable in U-Boot.
Here is my U-Boot environment:
baudrate=115200 loads_echo=1 ethaddr=00:E0:0C:00:8C:01 eth1addr=00:E0:0C:00:8C:02 ipaddr=10.82.19.159 serverip=10.82.48.106 rootpath=/nfsroot0/u/timur/itx-ltib/rootfs gatewayip=10.82.19.254 netmask=255.255.252.0 hostname=timur-dev bootfile=/timur/uImage loadaddr=200000 netdev=eth0 tftpuboot=tftpboot $loadaddr timur/u-boot.bin; erase fe700000 fe77ffff; cp.b $loadaddr fe700000 $filesize; cmp.b $loadaddr fe700000 $filesize tftplinux=tftpboot $loadaddr /timur/uImage ethact=TSEC0 bootargs=root=/dev/nfs rw nfsroot=10.82.48.106:/nfsroot0/u/timur/itx-ltib/rootfs ip=10.82.19.159:10.82.48.106:10.82.19.254:255.255.252.0:timur-dev:eth0:off console=ttyS0,115200 stdin=serial stdout=serial stderr=serial
And here's what Linux says when it boots:

As you can see, it's using the wrong IP address. It's using the one hard-coded into the kernel's configuration. I thought 'bootargs' was supposed to override that?
