Sure, that's no problem guys.  I'm pretty bad at remembering to use a
license from the start (no one will ever use this script.. ;) )..  I
usually use a simple MIT/X11 license, so that should be forward
compatible with what you guys need..

I'm the primary author for most of it, if I draw the 'significant'
line before localizations.. (German(1) spelling versions of "Disk")
So that leaves one author for dealing with "/dev/mmcblk0[p]" (2)

So i'll contact Mario and hopefully get his blessing.

 Ok; I added Copyright 2010 Robert Nelson <robertcnelson@...> at
 the top of our fork; thanks!

 I just removed the need for the translation in our fork of the script
 (changed "sudo sfdisk [...]" calls to "sudo LC_ALL=C sfdisk [...]")

 You might want to do the same for your script, to support any language.

> So that leaves one author for dealing with "/dev/mmcblk0[p]" (2)

 Apparently, we don't have this feature; I guess our script doesn't work
 on real MMC drives on laptops, only on USB ones.

 Our version was GPLv3 licensed; I'm not sure whether it's GPLv3+ or
 GPLv3 though.  I think it would be best to move to BSD style licensing,
 but that needs some kind of approval.  Our version is in
 lp:linaro-image-tools BTW (linaro-media-create script).

   Thanks for your help in sorting this out!

Thanks Loïc, that definitely will work alot better.  I was playing
with LANG='s this morning not have much luck, wish i was bi-lingual.

Yeah i didn't run into that myself till this summer with my new laptop
with built-in mmc card..  So it'll probally come up at some point as a
bug for you guys..

We really need to fix the boot loaders here. Anything that writes
to SD cards at unaligned sectors is rather broken, better make sure
that setup_sdcards always aligns the start of each partition to
multiples of 4MB from the start of the medium, and that all boot
loaders know how to deal with this!

I know you found a workaround with fdisk so you're probably no longer
using parted, but I was wondering if you were able to use parted to
change the geometry in the partition table to 255heads/63sectors as the
boot rom seems to require?

I ask because I'm working on converting our script to python and it'd be
nice if I could use python-parted for that, but it doesn't seem to be
able to.

Cheers,

Actually with current x-loader/u-boot the 255heads/63sectors isn't a
hard requirement anymore for the boot partition, so i've dropped it..

https://github.com/RobertCNelson/omap-image-builder/blob/master/tools/setup_sdcard.sh#L348

So far tested on:

Beagle B6 (oldest still booting beagle i have, any boards before that
had serial-ic overheating problems and eventually die under warrente.)
Beagle C2 & C4
Beagle xM A2

with angstrom's: MLO-beagleboard-1.44+r16 & u-boot-beagleboard-2010.03+r65

Panda A1

with mlo/u-boot from: http://gitorious.org/pandaboard

So right now i use parted to create the second partition.  We could
drop fdisk for the first, if we could figure out how to make parted
create a partition starting at the first cylinder.

For example, I've tried this and it doesn't boot:

I thought the 255h/63s requirement came from the boot ROM?

I partitioned a card with the exact same commands you use in
setup_sdcard.sh (fdisk to create the boot partition and parted for the
root one), and then used our script to populate it (without changing the
partitions), but it didn't boot.  This is what I got on my xM.

That was my impression to for the last couple years, but we had
discussion about it on the beagleboard group.  The rom doesn't care,
it was x-loader that was coded for sector 63..
