I am on barebox 2010.05.0-00446-g02f7dfe-dirty (Aug 23 2010 - 10:05:28).

I need to store the Env onto dataflash. While using u-boot, the env is
written to  0x4000 in the dataflash.

Which of this could be the  Data-flash device?

9263-EK:/ ls -l /dev/
/dev/zero                /dev/defaultenv          /dev/mem
/dev/ram0                /dev/nand0               /dev/nand_oob0
/dev/phy0                /dev/nor0                /dev/self
/dev/env0                /dev/nor0.barebox        /dev/nor0.bareboxenv
/dev/nor0.kernel         /dev/nor0.root

9263-EK:/ ls -l /dev/defaultenv
drwxrwxrwx          0 .
drwxrwxrwx          0 ..
drwxrwxrwx          0 dev
drwxrwxrwx          0 env
-rwxrwxrwx          0 uImage

Tried on /dev/defaultenv to get this , and stalls:-

9263-EK:/ unprotect  /dev/defaultenv
9263-EK:/ saveenv
saving environment
cfi_protect: unprotect 0xf1851002 (size 131072)
