Hello everyone, In the spirit of reaching out to the Linaro community, I'd like to engage in some conversation with those working on the HardFP ABI switch and toolchain effort, since we will shortly be doing the same in the Fedora ARM community. The intention is to support hardfp in time for the Fedora 15 ARM release, which *will* lag behind the x86 F-15 release. Anyway. I could do with some pointers to the current state of things, and who I should talk to and engage with at the LDS in another week. I will be there representing the Fedora ARM community. And I look forward to meeting those of you who don't already know me from other lives ;) Jon.

[PATCH 0/3] Fix Tegra devicetree support

by Stephen Warren

I tried out: git://git.secretlab.ca/git/linux-2.6.git devicetree/test plus the following commits from jk's dtbimage branch: 4c2eddb89542f73fe626813e3cdafc789f931aec arm: dtbImage support 4cb80ac96489220554d28f6fde527aeef83e628b arm/dtbimage: copy dtb blob to offset from image base A local patch to modify the Tegra devicetree support to support Seaboard instead of Harmony. ... on an NVIDIA Tegra Seaboard board. This patch series includes fixes to that branch to get Tegra booting to user-space. Note that soon after user-space starts, the system still crashes with: Unhandled prefetch abort: debug event (0x002) at 0x40e97714 However, this happens with or without actually providing a devicetree image to the kernel (I modified jk's dtbimage wrapper just to jump straight to the regular kernel startup, thus not providing a devicetree at all). So, I suspect it's some unrelated issue. I'll try to follow up and solve that too. Stephen Warren (3): ARM: Tegra: dt: Compile fix; tegra_common_init removed ARM: Tegra: dt: Fix machine desc to match other boards.

Help on general file sharing

by Shawn Guo

I have one 35MB tarball to share with Linaro folks. It's too big to distribute through email. Is there any infrastructural solution for such general file sharing purpose? (The launchpad PPA is for package than general file sharing, and I do not want to bother.) Thanks. -- Regards, Shawn

linaro-image-tools trunk branch moved

by James Westby

Hi, I just moved linaro-image-tools trunk to be owned by a new team, so that it is no longer using linaro-maintainers, which wasn't really appropriate here. The new branch is at https://code.launchpad.net/~linaro-image-tools/linaro-image-tools/trunk lp:~linaro-image-tools/linaro-image-tools/trunk Please let me know if there are any issues with this. Thanks, James

Initial benchmarks for this toolchain can be found at https://wiki.linaro.org/JimHuang/Sandbox/LinaroToolchainAndroidBenchmarking * An Android platform code branch for direct evaluation of the Linaro toolchain. * Initial low hanging fruit optimisations; integrated and upstreamed to AOSP (16 patch sets currently). * Mouse support for developer convenience on the Panda image. * The 0xBenchmark package comes pre-integrated into the builds for benchmarking and demos. * Four images based on Ubuntu 11.04 including ubuntu-desktop, nano, developer and ALIP. * linaro-image-tools support for installing Android images on an SDcard * Support for 11 different developer boards including the newly added Freescale iMX53 LoCo board. Using the Android-based images ============================= The Android-based images come in three parts, system, userdata and boot. These need to be combined to form a complete Android install.
