Hi guys,
Here's the situation:
We applied the following patches to an original u-boot source code (2011.09 version):
[U-Boot] [PATCH 1/2] Tegra2: Make XTal speed configurable [U-Boot] [PATCH 2/2] Tegra2: Add support for Toradex Colibri T20 board
And we use the antmicro patches for the Colibri T20 available on http://antmicro.com/blog.html (category ARM) Their patches are used to add the USB drivers for using the USB-to-Ethernet port.
Then, we take the following patches:
[U-Boot] [PATCH v2 0/8] Tegra2: Implement SPI flash and saved environment
The problem is that this patch is for the Seaboard. We adapted it for the Iris Board but this ain't working. We wonder if this patch is the right one.

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.
Sorry I don't know anything about that particular board either.
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?
Where is your environment supposed to be stored? If you are booting from NAND or MMC then you could store it there. There are various CONFIG_ENV_IS_IN_... variables to define depending on where you want the environment. The README file lists each of these and explains how to use them. You also need to define CONFIG_CMD_SAVEENV or perhaps better #include <config_default.h>.
We don't have much experience in embedded systems so a little help from
you
would be much appreciated.
OK, please reply on this thread if you have further questions.
Thank you in advance
Regards, Simon
