I can see the new env variable (e.g. set serverip 10.0.0.1) at the end of the saveenv area in flash (after I do a saveenv). (the original entry is removed from the list in flash, and the new updated entry is added to the end of the list in flash).
Still, when I reboot u-boot, I don't get the new environment variable updated from flash.
What am I missing?
Thanks. Suresh
Please don't top post.
Are you using DHCP (BOOTP)? If you are, serverip is probably being sent
by your DHCP server and overriding the value you have set in your env.
I'm assuming you are *not* getting env CRC failure warnings on boot.
If neither of the above guesses solve the problem, please copy what is printed to the console on start up. Without more information, we're just guessing.

Thanks, Jerry.
Sorry for the previous top post.
Your guess is right!
Upon looking more carefully at my log, I see
"bad CRC, using default environment"
In my boot-up log.
I am looking thru the code to see why I might have a bad crc.
Meanwhile, any guesses as to why I have bad crc?
Could I have ported code from u1.1.3 to u1.3.4 incorrectly?
Or could I have accidentally ignored some "change" from u1.1.3 to u1.3.4?
Thanks.
