Getting started with Linux

Hi.
I've tried in a couple of hours now to get Angstrom running on my mini2440,
but I haven't been able to this!
I'm able to restore the flash completely with the NAND DUMP here:
http://mini2440.sv-design.at/
But if I build my own image with Angstrom's online builder
(http://www.angstrom-distribution.org/narcissus/), I can't get it running.

The errors which occours can be everything from the uBoot stopping at
reading the jffs2 file from the SD card, or booting errors (uncorrectable
error) while loading the filesystem - which ends with ": No init" error!

I've tried following this guide too, but I haven't been able to find the
correct files. http://narnia.cs.ttu.edu/drupal/node/131


Do you guys know how to fix this, and what is the problem?
Also...

1. Is it possible to use images build from Angstrom's online builder?
2. Is it possible to load images directly from SD card, even if they are
bigger than 64MB (mini2440 RAM size)?
3. Is it possible to have the GCC compiler (make and make install) on the
mini2440 - so I can install fx TCL and Eggdrop?

Best Regards
Thomas Jespersen

Had to have a look myself (as I spent quite a bit of time on that tutorial)
and it appears they have removed the files for that project.

Perhaps, drop Florian an email.

Thomas,

Had another go at Narcissus.  With the u-boot and the kernel that came in
the package quoted in the tutorial at:
http://narnia.cs.ttu.edu/drupal/node/131
I managed to get a <simple console only mini2440 version to come up with a
command prompt and using a usb keyboard navigate around the directory
structure.

The back light went out after a few minutes, which is restored by hitting a
key.  Don't recall this feature with the root filesystem that was used in
the above tutorial.

Think the answer to #2 is you can RUN images bigger than 64M from SD, but
not load them to NAND.

#3 my understanding is that native compilation is difficult.  Maybe the
situation changes with 1GB flash.

P.S.

I tried the advanced option and adding in X11 and it fell-over.  I noticed
a BIG red X beside some of the options while building the image . . . maybe
that's why it didn't work!

I got the console type of Angstrom working too, but it would be nice with a
GUI. But GUI doesn't matter as long as I can install TCL and install/run
Eggdrop...

Then how do you load an image from a SD card? Which parameters should I set
in u-boot, and how should the SD card be formatted and what about the image
itself?

NOTE: The red crosses mean that it couldn't be installed (bitbaked) into
the package! So it isn't included...

This links is excellent !
I was about doing the same with a exe (Qt like) software

Is it working if you choose X11 + additional packages with Qt ?

X11 - no

complains about <angstrom task gnome>

Did a Goggle search and this looked promising:
http://elinux.org/ECE597_OpenEmbedded_Issues_and_Problem_Solving

but of course we don't get to see what is going on behind the scenes! 

Needs someone with some relevant experience!

Thomas,

Have you tried the tutorials here:
