This How-To is meant to be a starting point for people to learn how access to the uboot environment from userspace.

This is my first wiki page so please be benevolent with the formatting :-)

In order to modify the uboot environment variables from userspace we will need a program called fw_setenv, we can compile this program ourselves from the u-boot sources, follow the instructions in this wiki page and then proceed to compile with (don't modify the .h file as it says in the tools/env/README file):

#Flash sector size ---> 40.000

#Number of sectors (ignored in NOR)----> nothing

Pretty easy right? wrong!!! The right values are:

#MTD device name ----> /dev/mtd2
