Hi all,<br>
<br>
OLPC Engineering had a trip to Taipei for the XO-1.75 motherboard<br>
bringup last week. The 1.75 machine lives in the same industrial<br>
design (display, case, batteries) as the XO-1/XO-1.5, but uses an<br>
ARM system-on-chip from Marvell -- the Armada 610/MMP2.<br>
<br>
There's still a great deal of driver and basic bringup work ongoing,<br>
but we're at a point where we can share details and photos:<br>

<br>
The grand plan is to first move to the new ARM motherboard in the<br>
old industrial design (XO-1.75), then move to that same motherboard<br>
in a new tablet industrial design (XO-3). Of course, there tend to<br>
be a lot of changes to OLPC's grand plans before devices ship!<br>
<br>
Software-wise, we're running XO-EC and Open Firmware at the low level,<br>
and Fedora 12 with Sugar and GNOME for the OS. We plan on moving up<br>
to Fedora 13 or 14 as they become available for ARM. (An easy way<br>
to help us out would be to help the Fedora ARM team with their mass<br>
rebuilds for newer Fedora releases.)<br>
<br>
As usual, we'll be running a Developers Program with these machines<br>
once we've got past the necessary initial hardware fixes and made a<br>
larger volume of boards. That's going to take several months, but<br>
we wanted you to know that it will be coming.<br>
<br>
Thanks!<br>
<br>
- Chris, on behalf of the OLPC Engineering team.<br>
