This page once was the home for the efforts to get Fedora 11 running on the XO-1 hardware, following in the footsteps of [[F11 for 1.5]]. Since that time, the work was completed and formalized into several OLPC OS releases known as the 10.1 series (for XO-1, starting at 10.1.2). For more information, see '''[[Releases]]'''. |
|||
OLPC is developing a new [[Fedora]]-based XO operating system, see [[F11 for 1.5]]) for the [[XO-1.5]] hardware revision. It includes various improvements and modernizations over the last released version ([[Release notes/8.2.1|release 8.2.1]] on 2009-05-13) for the [[XO-1]] hardware shipped to many [[deployments]] and [[G1G1]] donors. |
|||
== Community-developed builds == |
|||
In July 2009 Steven M. Parrish took over creating builds of Fedora 11 the XO-1 from Daniel Drake. |
|||
=== Current release: os5 === |
|||
This build includes: |
|||
Addition of Typing Turtle & Words activities, added to favorites as well. Added ntp, |
|||
ntpdate to base OS. |
|||
Create custom .asoundrc file for TamTam |
|||
Builds can be downloaded from http://dev.laptop.org/~smparrish/xo-1/builds/ |
|||
The usual cautions apply: |
|||
* this is development code |
|||
* you will need to request a [[developer key]] |
|||
* you need to know how to issue firmware commands ([[OFW FAQ]] is one starting point) |
|||
* there will be bugs! |
|||
==== Installation instructions==== |
|||
At the firmware prompt, use <tt>copy-nand</tt> to install os5.img with os5.crc, '''overwriting your XO-1's files'''. |
|||
You ''may'' be able to use Live USB techniques to create a bootable USB from os5.iso; |
|||
see earlier guides on [[Rawhide-XO]]. |
|||
=== Earlier builds === |
|||
See http://dev.laptop.org/~dsd/f11-xo1/ |
|||
== Notes on how to create XO-1 builds == |
|||
''People presumably are following these steps to create.'' |
|||
Here's how you might do it: |
|||
Prerequisites: Fedora 11 system, with sudo access and a decent amount of disk space. |
|||
yum install git livecd-tools mtd-utils crcimg |
|||
As your regular user, check out fedora-xo: |
|||
git clone git://dev.laptop.org/projects/fedora-xo |
|||
In [http://dev.laptop.org/git/projects/fedora-xo this git tree]: |
|||
* master branch is currently unused. |
|||
* xo-1.5 branch contains all build scripts for the new OS release for the XO-1.5. |
|||
* xo-1 branch contains all build scripts for the for the XO-1 |
|||
git checkout --track -b xo-1 origin/xo-1 |
|||
As a quick summary of the most important files, |
|||
; olpc-base.ks and olpc-desktop.ks : the [http://fedoraproject.org/wiki/Anaconda/Kickstart kickstart] files used to make the core software image. |
|||
; livecd-creator : processes the core software files to create a .iso image. |
|||
; livecd-iso-to-xo.sh : converts that .iso into an image that can be flashed onto XOs. |
|||
; Makefile : wraps up the whole process. |
|||
The ongoing process will be to synchronize the xo-1 branch with any new changes made to the xo-1.5 branch. Really, there are only a few differences that must be maintained between the 2 branches. You can see these differences with this command: |
|||
git diff 38951c7..xo-1 |
|||
The above command shows the state of the XO-1.5 branch at the point of last synchronization compared to the XO-1 branch. The differences that have to be maintained (for example, geode video driver, jffs2 file-system) can be seen here, but even this was an unclean synchronization and could be made cleaner (there is some "noise" in the diff). |
|||
The next step is to look at all of the recent changes that have been made to xo-1.5 and merge them into xo-1. I would do this by comparing the 2 trees as follows: |
|||
git diff xo-1 origin/xo-1.5 |
|||
Your task is to apply all the hunks of this diff (excluding ones that are specific to the XO-1.5 hardware) so that the output of this command looks similar to (or better than) the output of the earlier diff - i.e. so that the only differences between the 2 branches are the handful of changes that account for the differences in hardware. |
|||
Even in current state (before merging any new changes), the xo-1 branch is ready for building and should produce a bootable build. Here's how you kick off a build: |
|||
mkdir output cache builddir |
|||
cd output |
|||
make -f ../Makefile os5.img |
|||
After some time, the output file "os5.img" will be ready for flashing onto your unlocked XO. |
|||
If you're happy with this process, the next steps are to publish your build by uploading it to a webhost, and then announcing it on the OLPC devel and Fedora-OLPC mailing lists. |
|||
If you are a known community member, OLPC would probably be happy to give you access to machines where you can run these builds from and host the downloads. Otherwise, this is still a possibility but you'd probably first be expected to make and publish a couple of builds on your own. Similarly, it should be possible to get you direct access to commit to the main fedora-xo repository. Once usable builds are being published regularly, you could also take over this wiki page. |
|||
I may have forgotten a few considerations in the above braindump, but if you're interested then the next step is to give it a try and write about any troubles on the devel@lists.laptop.org mailing list, and we'll help you figure it out. -- [[User:DanielDrake]] 2009-07-14 |
