Appalayagari Sreedhar (INDIA)
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.
