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

It would definitely be helpful if you describe which actual problem
you see?
Is the "saveenv" command not available at all? Does it reaturn any
error messages? Which exact messages?
Best regards,
Wolfgang Denk

Hi Wolfgang,
they don't have any storage media. They PMed me and I explained to them. Anyway,
I suspect we won't be getting any further here as they decided to use out-of-
tree port (sadly).

Sorry I don't know anything about that particular board either.

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>.

OK, please reply on this thread if you have further questions.

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.

OK. There is a USB series on the list also. I can see a tar file on
that web page but didn't look at it. I presume it works for you ok so
that is fine.

Well the series includes the driver support but also turns on the
environment options in seaboard.h. So at the least you would need to
turn these options on in your config file.
Also check that the pinmux is being set in tegra2_spi.c. The final few
patches to do this cleanly for Seaboard were NAKed (NS16550 changes
and buffering) so this might be slightly different on your platform.
It looks like you use UARTA so won't have the SPI/UART conflict, but
you still need to make sure that SPI's pinmux is enabled.

Simon
