For those who are interested. We have a tracking-panda build running with this tree at https://android-build.linaro.org. I've tested: https://android-build.linaro.org/builds/~linaro-android/tracking-panda/#build=9 It passes: Boots 0xBench Busybox YouTube Ethernet ADB GLMark2 Wi-Fi Bluetooth It fails: Resumes For reference, here's the 11.09 test wrap up: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AnpUtxWjZbP9dGFDUk5kNXBoeWZDb3MyUmJ4cnBHTEE&hl=en_US#gid=0 It also only boots on the 4430 not the 4460. The following bugs are related to this effort so far: Android tracking-panda build 9 fails to boot on 4460 https://bugs.launchpad.net/u-boot-linaro/+bug/869537 Android tracking-panda build 9 crashes during suspend https://bugs.launchpad.net/linaro-android/+bug/869514 __linux__ is not getting defined in android-build https://bugs.launchpad.net/linaro-android/+bug/868550 -Zach > -Andy > > -- > Andy Green | TI Landing Team Leader > Linaro.org │ Open source software for ARM SoCs | Follow Linaro > http://facebook.com/pages/Linaro/155974581091106 - > http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog > > _______________________________________________ > linaro-kernel mailing list > linaro-ker...@lists.linaro.org > http://lists.linaro.org/mailman/listinfo/linaro-kernel > -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
