Hi again, after a bit more debugging I came to the conclusion that there was no problem with the saving of environment variables to dataflash, but the problem is with reading them when the board 'env_init' is called and dataflash isn't initialized jet. After a bit of research I stumbled upon a patch posted by Hong Xu http://patchwork.ozlabs.org/patch/108025/ still under review which solves the problem. I understand that the solution isn't the most elegant one, but it enables the atmel based boards with dataflash to function normally which isn't the case with the default tree.

I'm using at91sam9g20ek_dataflash_cs1 and at91sam9260ek_dataflash_cs1 config on my test EK platforms. When I try to add or modify environment variables and then save them with "saveenv" everything seems OK but nothing actually gets written.
