Running a short android-build - LAVA CI cycle

by Paul Sokolovsky

Hello, When testing Android-build to LAVA integration (not the builds themselves), it's sometime beneficial to have quick build cycle which build something (just anything) without error and submits that to LAVA, to avoid ~1hr wait for the normal build. One way to achieve that is to add "MAKE_TARGETS=userdatatarball" to the build config, as exemplified with https://android-build.linaro.org/builds/~pfalcon/lava-test/ . Build then takes ~12mins, lower-bounded by repo checkout time. Of course, that won't produce complete Android build, so validation in LAVA will fail. -- Best Regards, Paul 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

ARM Cortex-A Programmer's Guide

by Roger Teague

Folks, if you are aware of this .PDF then please ignore. If not then you may find the ARM Coretx-A Programmer Guide a useful resource. Developed earlier this year it's already proving to be a valuable resource if you are looking for more programming tricks for your arsenal. The tone chosen is lighter than the usual ARM documentation and the ARM publications team would be interested in your feedback. Details are in the book . You can get this document at http://bit.ly/CortexAProg<http://www.linkedin.com/redirect?url=http%3A%2F%2Fbit%2Ely%2FCortexAProg&ur…> Unfortunately, we've been forced to put it behind a click-through license and you would therefore need to login to http://www.ARM.com<http://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2EARM%2Ecom&urlhash=g…>. However, this is the same login for downloads, forums, blog comments, support cases... So it's not for single use!

Android build failure

by Angus Ainslie

I have a android manifest that builds fine on my local build server with -j4 for concurrent makes. The same manifest fails to build on android-build.linaro.org The log is here https://android-build.linaro.org/jenkins/job/angus-akkea_smdkv310/6/console… Is there something I can add to the build variables to disable the concurrent make ? This would be just to debug the manifest file and then re-enable it afterwards Thanks Angus -- Angus Ainslie <angus.ainslie(a)linaro.org> Team Lead, Samsung Landing Team
