If you ask nicely and give us the necessary failure info I'm sure
we can tell you what you need to tweak to make it work again.
The problem is that earlier versions had a separate partition on the
built-in nand where the olpc.fth script (used by OFW) resided. That
partition was defined by the running operating system as _block_ device
mmcblk1p1 (on raw device /dev/mmcblk1 - and was mounted (or could be
manually mounted) to /bootpart.
With 12.1.0 builds, the running system does NOT see any raw device
/dev/mmcblk1 (nor any block partition on that device). It does see
several raw _character_ devices /dev/mtdx, but I don't know how to
access the corresponding partitions (assuming that's what they are).
One bypass would be to boot with an USB stick plugged in to the XO-1,
which provides a /boot directory with the appropriate olpc.fth in it.
Another bypass (which I haven't had time to explore) would be to boot
the XO-1 from an USB stick which has an older system version on it, then
update the XO-1 nand when mounted within THAT operating system.
[By the way, I have not found instructions on how to use the 'tree.
tar.lzma' file to fashion an XO bootable (self-contained) USB stick.]
----
Please (I'm trying to ask nicely!), can you all tell me what I need to
tweak to make "customizing the olpc.fth" (plus run 'rpm -U kernel...')
be effective on 12.1.0. [ I know how to make them work on 11.3.0. ]
Thanks, mikus
