[Buildroot] how can I change IP numbers when using 'defenv'?

[Buildroot] how can I change IP numbers when using 'defenv'?

[Mats Iderup]

Hi,

I am trying to change the default IP settings before using the 'defenv'
command in U-Boot on an at91sam9260ek board.

I have changed ip, serverip, gatewayip and ethaddr in
"at91sam9260dfc_defconfig" and then configured a minimal system without
fs and any extra target packages.

Also searched hole buildroot tree and changed every existing ?ip,
serverip, gatewayip and ethaddr in files like Config.in and cmd_defenv.c
to my wanted ip numbers.

Then using 'make' to generate only bootstrap and u-boot binaries.

NOW to the problem:

After downloading, booting the board and invoking the 'defenv' command
I still get the original settings:

len=149: root=/dev/ram rw initrd=0x2118C000,6000000 ramdisk_size=15360
ip=10.175.196.18:10.175.196.221:10.175.196.1:255.255.255.0
console=ttyS0,115200,mem=64M

Would appriciate any hint on how/when/where these IP settings can be
changed.

regards

Mats

Ok,

I find some hints.

?U-Boot> defenv
U-Boot> run config
U-Boot> run get
U-Boot> bootm 21000000


New environment settings is fetched from
host /tftpboot/autoscript.at91sam9260dfc
when invoking the 'run config'.

Still bootargs holds old variables.

Perhaps also updated when I also build rootfiles......

thanks

Mats
