New builds are announced on the devel mailing list.
XO-1.75 and XO-1.5
To install from Open Firmware on an unlocked XO-1.5 or XO-1.75, download a .zd file to a USB drive.
Insert the USB drive into the XO, get to the Ok prompt and type:
fs-update u:\X.zd
Where X.zd is the file you downloaded, for example 21008o1.zd (for XO-1.5) or 21008o2.zd (for XO-1.75).
XO-1
To install from Open Firmware on an unlocked XO-1, download the .img and .crc files to a USB drive.
Insert the USB drive into the XO-1, get to the Ok prompt and type:
copy-nand u:\X.img
where X.img is the .img file you downloaded, for example 21008o0.img.
Online upgrade
For updating from a previous release to a 12.1.0 development build, or from one 12.1.0 development build to another, you can use olpc-update. For example, to update to build 9, run one of the commands below in the Terminal activity, depending which laptop model you are using:
sudo olpc-update 12.1.0d_xo1.75-9 sudo olpc-update 12.1.0d_xo1.5-9 sudo olpc-update 12.1.0d_xo1-9
Developers
The release is built with Build system::OS Builder version Build system version::5.0.x (master) under Build platform::Fedora 17, using f17-xo1.ini, f17-xo1.5.ini and f17-xo1.75.ini at this point in the development process. The f17, f17-xo1, f17-xo1.5 and f17-xo1.75 RPM dropboxes are used.
Fedora package inclusion process
For contributions in the form of updated RPM packages that are part of Fedora, the process is a little complicated due to the fact we work with multiple architectures and ARM is not yet a primary Fedora architecture.
The entire process is explained below. However, only the first and last steps are required. Feel free to skip some or all of the remaining steps - just make sure you leave a note on an "add to build" ticket noting which steps you have done. Daniel and Peter are more than happy to take on the packaging work on your behalf, and they can lump it into batches.
- Produce source tarball, upload to relevant place.
- Commit spec file to Fedora git, push and build for x86
- Commit your change on both the f17 and master branch. Suggestion: commit on F17 branch, then use git merge to fast-forward master to the same commit.
- Ensure you are on the f17 branch.
- fedpkg push
- fedpkg build
- Submit an update for F17.
- fedpkg update
- When bodhi emails you saying that your F17 update can be pushed to stable, push it.
- Put the relevant trac ticket in "add to build" state, noting which of the above steps you have completed.
ARM is intentionally left out of the picture here. Your package will be built automatically on ARM, but only once it gets pushed to stable (updates-testing does not currently get built for ARM). To avoid the delay of several days before this happen, Peter Robinson will make an ARM build based on what was pushed to updates-testing and maintain it in his dropbox until it is officially built for Fedora-ARM. Please leave these builds to Peter so that it can be managed in a central place.
Bug reports
We are now looking for bug reports on all levels - system, Sugar, activities, ...
Sugar-specfic bugs and activity issues should be filed at http://bugs.sugarlabs.org. System-related bugs should be filed at http://dev.laptop.org. If in doubt, ask on the mailing list first, or file at OLPC and let us take care of it for you.
For OLPC tickets, leave the milestone field blank but mention clearly that you are testing 12.1.0, your bug report will then be triaged into the appropriate place.
