BB C4 and latest Angtrom Demo u-boot problem

Maybe your SD card is not properly formatted or the MLO is not the first file copied onto a freshly formatted card and it is defaulting to booting from NAND.

Simple your SD card is not formatted "exactly" the way the internal
X-Loader wants to read it..

There are a couple tools/scripts posted on the net to accomplish this,
but here's my way:

Make sure you use a spare sd card.. (i don't want you to lose your
existing work.)

Finally I managed to create a full bootable SD!
Many thanks to all for the support!
I followed the instruction posted by Robert (almost).
better: i followed this:
http://nishanthmenon.blogspot.com/2008/08/how-to-boot-beagle.html
because the script from the page linked don't works for me (problem
with fdisk -l, I'm on kubuntu 10.04)
Now... another little question:
On a page that I've read only todai I've found a little comment about
using fdisk to format the SD:
they say to not use 50 as size for the boot partition but 51... but
everywhere I've found 50...
could this be the problem?
For now... many thanks for the support and for the patience.. to all
of you!

Now I got also a problem with the Angstrom demo. I wanted to show a
workmate the demo image.

I downloaded all files from the angstrom site, formatted the SD-card
as required and copied (in this order) MLO and u-boot.bin to the boot
partition and so on. (I simply followed the instructions)

Now, it doesn't boot.

The output on the serial console shows, when I only power up the
board:

Sven,

Type this into u-boot:

nand erase 260000 20000

That will reset your uboot env to something working.

Thank you,

that really solved the problem.
The error seemed so strange, as it only occured on one of two Rev C4
board.

Thank you very much (again),
Sven
