11.2.0
11.2.0 is the project previously known as "F14 for XO", now formalized into an official OLPC OS release. The full release plan is available at 11.2.0/Release plan.
Summary
11.2.0 is an OLPC OS release based on core system updates to Fedora 14, Linux 2.6.35, Sugar 0.92 and GNOME 2.32, planned to be released in June 2011. The target platforms are Target platforms::XO-1, Target platforms::XO-1.5, and XO-1.5 High School Edition.
Known issues in development/testing releases
The (draft) Release notes/11.2.0 page describes limitations and issues that we anticipate will be present in the final release. In addition, as we are still in development, so we're still encountering serious issues here and there that we'll fix as we move towards release. Those cases are documented here.
XO-1.5 firmware complains that "not all blocks were written"
When installing the new image with fs-update on an XO-1.5 laptop that has a development firmware version, a WARNING message may appear at the end of the process stating that not all blocks were written.
Unless your download has become corrupt, this error message is incorrect and can be ignored. Simply power off the system and turn it on again to boot into the new release. Your firmware will then be automatically upgraded (in the presence of external power) in order to solve this problem for any future installations.
The final release image will include some trickery that detects when old firmware is in use during the installation stage, and hides this invalid error.
os21: XO-1.5 wireless card reset bug
<trac>10944</trac>: In build 21, a minor kernel bug causes the wireless card to be reset during every resume, destroying any established connections. Fixed in build 22
os20 and os21: olpc-update broken
<trac>10942</trac>: If using olpc-update from os20 or os21 to another image, things will fail badly due to a misconfigured /versions/running symlink. It will delete the current version (perhaps rendering the system unusable on reboot) and then fail to update with a strange error regarding the /versions/contents directory. Fixed in build 22, but you will have to reflash to install this new version - sorry!
XO-1 JFFS2 olpc-update to os20 broken
<trac>10929</trac>: If starting with an older release that used the JFFS2 filesystem (e.g. 10.1.3, 8.2.1) and using olpc-update to update to 11.2.0 build 20, you will find that it works fine during first boot, but then fails to boot the second time (and onwards). You'll have to reflash to recover from this, sorry. Fixed in build 21.
Status
Status: Status::in development

Planned release date: Release date::2011-07-18
Download
Development builds are available here:
http://build.laptop.org/11.2.0
New builds are announced on the devel mailing list.
XO-1.5
To install from Open Firmware on an unlocked XO-1.5, download a .zd file to a USB drive. Choose the correct one: there are several. Files which end in .zd2 are for 2GB media and .zd4 is for 4GB media.
Insert the USB drive into the XO-1.5, get to the Ok prompt and type:
fs-update u:\osXX.zdN
Where osXX.zdN is the file you downloaded, for example os22.zd4.
XO-1
To install from Open Firmware on an unlocked XO-1, download the .onu and .uim files to a USB drive.
Insert the USB drive into the XO-1, get to the Ok prompt and type:
update-nand u:\osXX.onu
where osXX.onu is the .onu file you downloaded, for example os22.onu.
(Watch out, there's a trap. Never use copy-nand for this release. copy-nand was for previous releases with .img and .crc files, but we no longer use it for .onu and .uim files. copy-nand might seem to finish okay, but your XO-1 won't start. If that happens, do it again using update-nand as above.)
Updating with olpc-update
To update to 11.2.0 using olpc-update, you can run:
XO-1:
sudo olpc-update 11.2.0_xo1-XX
XO-1.5:
sudo olpc-update 11.2.0_xo1.5-XX
Where XX is the build number you wish to install (e.g. 22). See http://build.laptop.org/11.2.0 for the list.
Developers
The release is being built with Build system::OS Builder version Build system version::3.0 (master) under Build platform::Fedora 14. The f14, f14-xo1 and f14-xo1.5 RPM dropboxes are used.
Bug reports
We are now looking for bug reports on all levels - system, Sugar, ...
Please file bugs at http://dev.laptop.org. Leave the milestone field blank but mention clearly that you are testing 11.2.0, your bug report will then be triaged into the appropriate place.
What happened to 11.1.x?
At the time of planning this release around Fedora 14 for XO-1 and XO-1.5, we are in the interesting situation where software development for the ARM-based XO-1.75 is restricted to developing around F12/F13. The 11.1.x space is therefore reserved for a F12/F13 release for XO-1.75. In the future, we hope to produce joint software releases for all 3 laptops.
This oddity is expected to be a one-off; as soon as Fedora/ARM reaches Fedora 14, XO-1.75 releases will be able to share the same base (and versioning) as XO-1/XO-1.5 releases.
