Ah.. I misunderstood you. When
Access to the jffs2 boot partition of the XO-1 NAND Flash is required
for any kernel upgrade ... so having it missing should be breaking
olpc-update.
I expect this will need to be fixed during development of 12.1.0, and
when it is fixed your access to the boot partition should be easier.
It isn't

And then January 2012 came, and some lunatic gave

block device on the linux side
But there __is__ no block device defined by the 12.1.0 operating system
when running on the XO-1. { Raw /dev/ubi0, whose partition contains the
root file system, is defined as a character device. } I don't want to

As a quick answer -- if
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

The thing is that XO-1.5 has about twice the XO-1 processing power and is quite

I was wondering if there is anyway to monitor the geode temperature on the XO-1.
I would like to test how far I can push it without ruining it.
Could not find the relevant info anywhere but I think I have seen at some point
that this may not be possible (due to limited connections?).
Is it possib
