I suggest starting simpler using https://pypi.python.org/pypi/jinja2-cli/0.6.0. Thank you, that really helps a lot. We want to trigger the LAVA jobs from Jenkins as well, and we need lots of metadata because the tests will be part of our release notes in the end. So no, this is definitely not more complicated than we need. In fact, this is a very good starting point for us. You should think about adding a chapter to the LAVA documentation about how to generate YAML job submissions via templates. I assume we are not the only ones facing this problem. And I had basically no experience with jinja2 at all before evaluating LAVA, so I would not have come up with the idea of using this mechanism for the job submissions myself.

LAVA test dependencies in jobs

by Anibal Limon

Hi, We are doing boot regression test using (in DB{410,820}c) an Android boot image that contains a ramdisk [1]. We aim to do functional testing in a way that if the basic testing fails the next test definition dosen't run, that's implies dependencies over -test entries in the job [2]. Does LAVA test shell provides this kind of functionality? If not, any idea to achieve this functionality. Regards, Anibal [1] https://validation.linaro.org/scheduler/job/1884978/definition [2] https://validation.linaro.org/scheduler/job/1884978/definition#defline117

Automation & Risk

by Neil Williams

The LAVA software team created a document to summarise the experience, so far, of automating devices for validation and that document formed the basis of a presentation at Linaro Connect in Hong Kong earlier this year by Steve McIntyre. The content has been living inside a wiki within Linaro but there have been delays in making the URL visible to anonymous viewers. I have therefore migrated the content to my blog: https://linux.codehelp.co.uk/automation-and-risk.html A link to the presentation is included. Available under CC BY-SA 3.0 and shortly to appear on planet.debian.org Please share with anyone involved in designing hardware which is likely to end up on your desk for automation support and anyone else who may be interested in the hardware challenges of device automation. A second shorter post on Firmware Best Practices will follow - some of the elements of that document were also covered in the presentation at Connect. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

[Lava BBB01 health check problems?!] Wrong Ramdisk Image Format - Ramdisk image is corrupt or invalid

Hello Folks, Long time no see. Seems that I am back (for limited time) to Lava testing, and after all the setups and catches 22, I managed to get to the bottom of it, within few days. I have interesting problem to report. vagrant@stretch:/etc/lava-server/dispatcher-config/device-types$ dpkg -l lava-server lava-dispatcher Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==========================================-==========================-==========================-========================================================================================== ii lava-dispatcher 2018.5-3~bpo9+1 amd64 Linaro Automated Validation Architecture dispatcher ii lava-server 2018.5-3~bpo9+1 all Linaro Automated Validation Architecture server ## Issue Background Issue CIP testing #16 seems to be very similar: Beaglebone Black health-check job is failing at restart ## Issue description Wrong Ramdisk Image Format Ramdisk image is corrupt or invalid ## Acceptance criteria The tftp 0x88080000 22/tftp-deploy-on2jld77/ramdisk/ramdisk.cpio.gz.uboot Using cpsw devtftp 0x88080000 22/tftp-deploy-on2jld77/ramdisk/ramdisk.cpio.gz.uboot The initramdisk is built by the following instructions: https://wiki.linuxfoundation.org/civilinfrastructureplatform/cipsystembuild… I used both BusyBox 28.0 and latest stable BusyBox 28.4 (failure seems to be the same)!
