Just for my list of tested min2440 variants: What type of SDRAMs and NAND is
your system using?

Authors of documentation are always welcome. But they are rare :-(

Take a look into the generic environment in "defaultenv/bin/". These scripts
are used when the system comes up. They are using the "/env/config" for
parameterization. Maybe these file will help you to understand how it works.

So, the changes in your environment are lost after reboot? Do you see any kind
of error message (like CRC sum errors)? when barebox comes up after reset and
tries to load the saved environment?
