saveenv?

Hi Pankaj,

You need to debug your flash writing. This is board and processor specific, and I have basically no knowledge of either so I can only give general guidance.

Try writing to flash using command line commands, erasing flash, etc. Once that works, figure out where in flash your env is being saved... see if anything is being saved there when you do the "saveenv", why it isn't being saved or why it is being corrupted.

Also, please honor u-boot email list etiquette: * HTML is not welcome on this list. * Please bottom post. * CC: the u-boot list on your replies or you won't get the benefit of the immense amount of talent that is subscribed to this list.
