[REPORT] 2011-03-10 Developer Platform team weekly report

by Jamie Bennett

Hi, The Developer Platform team weekly report for 2011-03-10 is now available and can be found at: https://wiki.linaro.org/Platform/DevPlatform/Status/2011-03-10 The report is also reproduced in full below. Regards, Jamie. -- Linaro Release Manager | Platform Project Manager -- * Period: (20110303-20110309) * PM: JamieBennett <jamie.bennett(a)linaro.org> * Past reports : https://wiki.linaro.org/Platform/DevPlatform/Status * Burndown information : http://status.linaro.org/linaro-foundations.html == Key Points for wider discussion == * The process to produce and upstream ALIP cross-compile fixes is slow, what can we do to speed this up? * Multi-arch changes are still landing to the Ubuntu archive, lots of testing is needed here. * Panda display issues are now resolved so more testing of images on the Panda board is possible. * The Nano image needs to be slimmed down further. Tom has proposed some changes but others need to review and comment on them. == Team Highlights == * LTTng 0.245 has been ported to the linux-linaro-2.6.38 kernel. The changes are available at: http://git.linaro.org/gitweb?p=people/aviksil/linux-2.6-lttng-linaro.git;a=… * Work continues on parts of kdelibs with the GL dependency removed from libplasma and kdebase-window-manager updated. * After many investigations the Panda non-display issue (bug:728603) has a fix. A config option change will enable the display to work with a knock-on effect of other bugs such as bug:720055 also being resolved. * A thumb2 enabled kernel build has been turned on after work by both the Kernel Working Group and the Developer Platform team. * Linaro's smallest full image, Nano, got reduced in size to 125mb installed. Proposed changes to eventually get closer to the 64mb installed target are currently in discussion. * libjpeg-turbo got further work this week as lintian errors were fixed. * Several more packages have been fixed for cross-compilation in the Ubuntu archive. * dpkg support for multiarch library installation is in the Ubuntu archive but needs another upload due to changes in the planned dpkg database format. There has also been some patches submitted to apt for the major multiarch blocker bugs as the team continue towards a true multi-arch solution. * Cross toolchain packages got reuploaded to the archive fixing recent issues. == Upcoming Deliverables == * Beta Freeze 2011-03-24 * New build of Linaro Linux kernel * systemtap v1.3 + cherry-picked fixes * apt fixes to Ubuntu * New dpkg to Ubuntu that implements support for the final multi-arch library paths == Risks / Issues == * '''MEDIUM IMPACT''': Peter Pearce reports that bootstrapping & making cross-compile patches upstreamable are slowing the rate of package fixing. The (current) alip package list will not be complete for beta freeze. * '''LOW IMPACT''': All multiarch work is landing past feature-freeze. Requires exception approval from the Ubuntu and Linaro release teams. == Miscellaneous == * Wiki pages of note this week: * http://wiki.debian.org/DebianBootstrap * https://wiki.linaro.org/Chromiumos/ChromeosWm

Efikamx bootloader help

by Per Forlin

Hi, If I mess up the u-boot in my efikamx smart book how can I install a new one? I tried booting with an SD-card image from http://www.powerdeveloper.org/asset/by-id/116. I guess this only works if I have a working u-boot in place. I don't have the serial/JTAG connector. Is this what I need in order to recover? Thanks, Per

Display support for Pandaboard

by Anand Gadiyar

Hi all, Per Nicolas' request, I've compiled a list of all patchsets needed to get functional display on the Pandaboard. There are 35 patches in all, over 6 series, plus one patch for the board file to enable the DVI support. I've set up two branches (against v2.6.38-rc4, and against the head of linux-linaro-2.6.37 as of today) to make it easy for people to extract and test these. They are available in my git tree here: git://dev.omapzoom.org/pub/scm/anand/linux-omap-usb.git in the display-patches-for-v2.6.38-rc4 and display-patches-for-linaro-37 branches respectively. I've updated the bug report for this issue (Bug #707038) with links to the component series, as well as the link to my tree above. (I'll make sure these two branches stick around - at least as a reference - until the patches make it upstream). @Nicolas, None of these have been queued up by the respective maintainers yet, so they aren't in linux-next as of today. However I believe there are no outstanding review comments for these. I can send a pull request for these if it's okay with you. Let me know if you need them based off any particular tag/commit/branch. - Anand

Cross toolchain source packages status

by Marcin Juszkiewicz

Ubuntu/natty got some cross toolchain updates recently so it is installable again. This gave me some free time to work on improvements. And this mail is an attempt to summary it and to provide some ideas/questions. = Introduction = During Emdebian sprint it was decided that my source packages will be used in Debian to provide cross toolchains for users in archive itself (as now Emdebian team autobuilds them into separate archive). We created crosstoolchain project [1] at Alioth and plan to keep Debian branches in git.debian.org repository [2]. = Existing branches = Speaking of branches - there are several ones in my git repository [3] and some of them are also present as Bazaar branches on Launchpad. This list follows: debian/experimental/armel-cross-toolchain-base debian/experimental/gcc-4.5-armel-cross debian/experimental/gcc-4.6-armel-cross debian/unstable/gcc-4.4-armel-cross Those ones can be used to provide cross toolchain for Debian. First one is really ugly as for now it contains a copy of eglibc and linux-2.6 packaging. I have to report few patches [4][5][6] for both components to get this situation sorted. GCC ones do not have any such problems. ubuntu/natty/armel-cross-toolchain-base ubuntu/natty/gcc-4.4-armel-cross ubuntu/natty/gcc-4.5-armel-cross Those ones will be soon sent for review/merge/upload into Ubuntu. ubuntu/not-used/gdb-armel-cross Superseeded by gdb-multiarch package - gdb 7.2-1ubuntu8 or newer required. ubuntu/ppa-backport/armel-cross-toolchain-base ubuntu/ppa-backport/gcc-4.5-armel-cross ubuntu/ppa-backport/patches Those branches are used to generate packages in Linaro toolchain backport PPA [7]. "/patches" branch keeps all patches which I use to alter components. = Status = During sprint I merged 3 branches of armel-cross-toolchain-base into one set of rules so today there are not differences between Ubuntu ones and Debian one contains extra debian/packaging directory with copies of eglibc/debian and linux-2.6/debian dirs. Generation of debian/control file is now inside of debian/rules so differences in build dependencies are handled. Switch between Ubuntu and Debian is sorted by using "lsb_release" (idea taken from gcc-4.5) and PPA build can be enabled by "touch debian/ppa". = Ideas = There was idea to generate just one source package from this (so it would be debian/experimental/armel-cross-toolchain-base branch) and generate all versions from it. I think that this will work but first we need to get Debian version into state which will be acceptable for inclusion into archive. = Problems = Main problem is debian/packaging/ directory in Debian version. I need review of [4] patch and then will report a bug against eglibc. = Multiarch versions (future) = When cross build dependencies will be working then we will get rid of armel-cross-toolchain-base package and replace it with binutils-armel-cross (or extend binutils-multiarch to contain "as" and rest of missing binaries). 1. http://alioth.debian.org/projects/crosstoolchain/ 2. http://git.debian.org/?p=collab-maint/cross-toolchain.git;a=summary 3. http://git.linaro.org/gitweb?p=people/hrw/cross-toolchain-packaging.git;a=s… 4. http://42.pl/u/2zj4 5. http://42.pl/u/2zj5 6. http://bugs.debian.org/611382 (merged into http://bugs.debian.org/550776 one) 7. https://launchpad.net/~linaro-maintainers/+archive/toolchain

problem with linaro-media-create

by Aneesh V

Hi, I am trying to prepare an MMC card to boot up Panda with Linaro daily build image. I downloaded linaro-image-tools from: https://launchpad.net/linaro-image-tools I installed all dependencies mentioned in the README and tried to run linaro-media-create like below: sudo ./linaro-media-create --rootfs ext3 --mmc /dev/sdb1 --binary /home/a0393566local/linaro/headless/linaro-natty-headless- tar-20110206-0.tar.gz --hwpack /home/a0393566local/linaro/hwpack /hwpack_linaro-panda_20110206-0_armel_supported.tar.gz --dev panda However, it crashes immediately with the following dump: http://pastebin.com/SV78dP8L Any idea what could be going wrong? Thanks, Aneesh
