2008-04-30 10:43:55     saveenv command usage

Hi,

 

My custom board has smsc9215 ethernet chip.

 

I have compiled smsc driver in u-boot and was able to succesfully bring the u-boot up.

 

once i get the ezkit prompt.

 

i am doing below sequence.

 

set serverip 192.168.19.2

 

set ipaddr 192.168.19.10

 

set ethaddr 00:11:22:33:44:55

 

after that is it necessary to

 

call saveenv command in the ezkit prompt?

 

if it is not called, will it cause any problem?

 

only thing i have observed is if i reboot the system, the configured values of serverip, board ip and ethaddr are lost.

 

Best Regards,Sreedhar

All changes you make to the U-Boot environment are made in RAM only. They are lost as soon as you reboot the system. If you want to make your changes permanent you have to use the <code>saveenv</code> command to write a copy of the environment settings to persistent storage, from where they are automatically loaded during startup:
