This is no help. Without any useful information.

You should also provide bootstrap log info.
I think the code is get from www.at91.com/linux4sam.
Anyway, I assume that you use the source code and package get for the upper website. If so, the u-boot environment you change is overlap with u-boot. (If you write the u-boot at offset 0x40000, the size is larger than 256K, that means: u-boot offset + u-boot size > 0x80000). So, when save environment, it will overwrite the u-boot, which cause this issue.
Please check it again. If all thing as I guess, you can change the u-boot offset to 0x20000, or change environment offset to 0xa0000. you can choose which you prefer.
