DHCP
Posted by: mylesdw ()

Can you point me in the direction of some instructions for getting an IP by DHCP during a 'normal' BOOTD of a Snapper 9260. I just want the IP without all the other dhcp_boot stuff.

I tried adding ip=any to the boot_args but this does not quite work...

Thanks
Myles

In U-Boot you can use the 'bootp' command to assign an IP address via DHCP. For example: 
Snapper> bootp
BOOTP broadcast 1
DHCP client bound to address 192.168.2.61

For Linux, you should add "ip=dhcp" to your boot parameters.

Got it now thanks; seems you also need to do

>setenv autoload no

in u-boot or it goes off and tries to load an image.

Is there a way of forcing the IP to be set by DHCP after booting?

If you want to get Linux to set it during boot, use the ip=dhcp or ip=any command line argument. If you want to assign it from the Linux command line well after booting, try the udhcpc program.
