[U-Boot] Help needed on Colibri T20 - Iris Board

[Stéphane Carvalho]

We are 2 engineering students from Fribourg, Switzerland working on a
embedded systems project.

The fact is that we're looking to setup U-Boot on a Colibri Iris Board
using the Colibri T20 module with NVIDIA Tegra 2 processor.

Since the Iris board is a relatively new board, it is difficult for us to
find information about it.

We managed to install a recent uboot on the board but it is not very
efficient. The major problem is that we aren't able to run the
*saveenv*command in order to save the environnement. Does anyone have
any ideas
about the problem? Or patches to recommend us?

We don't have much experience in embedded systems so a little help from you
would be much appreciated.

Thank you in advance
