snowball hang issue with latest android builds.

by Vishal Bhoj

Hi, Snowball builds #327,#330,#332 seem to hang when we run the script mentioned in this bug: https://bugs.launchpad.net/igloocommunity/+bug/1014650 I have seen that system hangs when I run Linpack[1]<http://android.git.linaro.org/gitweb?p=linaro/benchmarks.git;a=blob;f=linpa…>under certain environments. Here is my observation : 1. System doesn't hang when I run Linpack Single/multi thread configuration as a normal application by launching and running it (using monkeyrunner in my case) 2. System hangs when I run the same application when I run the application in conjunction with androidscreencast<https://wiki.linaro.org/Platform/Android/AndroidScreencast>. I could be that system hangs only at some high loads . [1] : http://android.git.linaro.org/gitweb?p=linaro/benchmarks.git;a=blob;f=linpa… Regards, Vishal

Help on Linaro source code download

by 钱大伟

Dear Sir/Madam, I am trying to download Linaro-android/staging-panda-11.11-release source code with repo and git. I followed the instruction in the following link https://wiki.linaro.org/Platform/Android/GetSource. Since the git port is blocked by my firewall, I have to use the http connection to download the code. When the download goes to the x-loader project, the fatal error happened with the following info: Cannot found https://git.gitorious.org/x-loader/x-loader.git/info/refs did you run the git update-server-info in the server side? While, when I tried to download the source manual with the following command, it works: get clone https://git.gitorious.org/x-loader/x-loader.git Would you please help me to figure it out? Best regards, David Qian

Thanks Ken, Android on QEMU writeup

by Zach Pfeffer

Thought this deserved a wide audience. Ken worked out how to run Android on QEMU and wrote up a wiki for it: https://wiki.linaro.org/KenWerner/Sandbox/AndroidQEMU Thanks Ken! It may be worth creating a little script that encapsulates everything so that people can just run it and go on their local box. -- 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
