It is important to see others walking the same route. My simple tests are running now thanks to the help of the nice people from the #linaro-lava chat. 1) Crazy me decided to use upstream u-boot 2017.05 instead of running some ancient version from 2014;) 1.1) which happens to have a different AUTOBOOT_PROMPT than the one Lava expects "Press SPACE to abort autoboot in %d seconds\n" instead of "Hit any key to stop autoboot" so (since) I would like to be able to stay as close as possible to upstream LAVA 2017.06 I patched u-boot[1]. Note that this could be fixed with LAVA as well - interrupt_prompt: {{ interrupt_prompt|default('Hit any key to stop autoboot') }} 1.2) also the SYS_PROMPT of upstream u-boot is different than the one expected by LAVA and again I made a u-boot patch[2]. Note that this could be fixed with LAVA as well - {% set bootloader_prompt = bootloader_prompt|default('U-Boot') %} 2) After some searching it turned out that LAVA set some funny variables in u-boot which made my kernel crash. (Crazy me decided to use a 4.9.x uImage without baked in address). Adding this: {% set base_high_limits = false %} to my bbb03.jinja2 file fixed it. ... obviously ;) Regards, Robert [1] https://github.com/RobertBerger/meta-mainline/blob/pyro-training-v4.9.x/u-b… [2] https://github.com/RobertBerger/meta-mainline/blob/pyro-training-v4.9.x/u-b…

Re: [Lava-users] [Linaro-validation] Further steps with Zephyr tests

Hello Milosz, Thanks for routing this thread to lava-users - when I made initial post to linaro-validation, I check my archive and so that e.g. Neil posts there frequently, but I missed that it's not official LAVA list.

Matt Hart actually showed me a ticket on that, so at least it's confirmed/known issue in works. But even with arduino_101 and frdm_k64f, I hit cases more than once when board(s) were stuck for extended time, but still were routed jobs to (which either failed or timed out). So, there may be problem with health checks, which either don't run frequently enough or aren't robust enough. arduino_101 is all the lone one, so if something happens to it, there's no backup. Etc, etc. [] > > So, the problem, for starters, is how to make LAVA *feed* the > > input, as specified in the test definition (like "2+2") into a > > board. > > Right. What I proposed was coding all the inputs in the test itself. Well, that would require bunch of legwork, but the biggest problem is that it wouldn't test what's actually required. E.g. both JerryScript and MicroPython Zephyr ports are actually interactive apps working over serial connection. And functional testing of them would be feeding something over this serial connection and checking that results are as expected. I'll keep in mind idea of "builtin" tests though.

I was too quick to hit reply.

OE/Yocto testcase

by Robert Berger

Hi, I succeeded in running the example Lava tests[1][2] on a Beagle Bone Black in my lab. Now I would like to test a core-image-minimal I built with Yocto and cooked up something like this[3][4]. The result is unfortunately this[5]. I guess one of the problems I have is this: lava-test: # ls -l /lava-38/ export SHELL=/bin/sh /lava-38/bin/lava-test-runner /lava-38/0ls: cannot access '/lava-38/': No such file or directory lava-test: # export SHELL=/bin/sh lava-test: # /lava-38/bin/lava-test-runner /lava-38/0 -sh: /lava-38/bin/lava-test-runner: No such file or directory Regards, Robert [1] https://validation.linaro.org/static/docs/v2/examples/test-jobs/standard-ar… [2] https://validation.linaro.org/static/docs/v2/examples/test-jobs/standard-ar… [3] https://github.com/RobertBerger/git.linaro.org-lava-team-refactoring/blob/m… [4] https://github.com/RobertBerger/git.linaro.org-qa-test-definitions/blob/mas… [5] https://pastebin.com/14pjxhiN
