Hi All, I am trying to setup a remote lab using Raspberry pi on my local network. I installed lava-server and a worker on my laptop and its working fine. I installed raspbian on R-Pi and follow the instruction given on lava site, but when slave is trying to connect to master its not getting any response, I am able to ping master from my R-pi board and default port 3079 is open on my machine. I used no encryption and use URL to connect master as follow. MASTER_URL="tcp://10.42.0.24:3079" LOGGER_URL="tcp://10.42.0.24:3079" I continuosly getting log messgaes like, DEBUG Sending new HELLO_RETRY message to the master (are they both running the same version?) INFO Waiting for the master to reply DEBUG Sending new HELLO_RETRY message to the master (are they both running the same version?) INFO Waiting for the master to reply DEBUG Sending new HELLO_RETRY message to the master (are they both running the same version?) Please, if any one have some idea why I am not able to connect please help. Thanks, Ankit

Typically, the build tests will have a different command syntax to the runtime tests (otherwise Jenkins would attempt to run both), so filtering should be possible. If the build tests are just a different set of binary blobs from the runtime tests, that may need a fix upstream in Zephyr to distinguish between the two modes. > I see, that makes some sense.

Yes, LAVA has support for pass, fail, skip, unknown. For POSIX shell tests, the test writer just calls lava-test-case name --result skip For monitor tests, like Zephyr, it's down to the pattern but skip is as valid as pass and fail (as is unknown) for the result of the matches within the pattern. > Anyway, these are rough ideas for the future.

There are known limitations with the USB subsystem and associated hardware across all architectures, affecting test devices and the workers which run the automation. LAVA has to drive that subsystem very hard for both fastboot devices and IoT devices. There are also problems due to the design of methods like fastboot and some of the IoT support which result from a single-developer model, leading to buggy performance when used at scale and added complexity in deploying workarounds to isolate such protocols in order to prevent interference between tests. The protocols themselves often lack robust error handling or retry support. Other deployment methods which rely on TFTP/network deployments are massively more reliable at scale, so comparing reliability across different device types is problematic. > [] > > > > - test: > > > monitors: > > > - name: foo > > > start: "" > > > end: Hello, ZJS world! > > > pattern: (?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)\. > > > > > > So, the "start" substring is empty, and perhaps matches a line > > > output by a USB multiplexer or board bootloader.

(That's a question to LAVA team definitely.) LAVA result handling is ultimately a pattern matching system. Patterns must have a unique and reliable start string and a unique and reliable end string. An empty start string is just going to cause misleading results and bad pattern matches as the reality is that most boards emit some level of random junk immediately upon connection which needs to be ignored. So there needs to be a reliable, unique, start string emitted by the test device. It is not enough to *assume* a start at line zero, doing so increases the problems with reliability. > > > > Well, beyond a simple output matching, it would be nice even for > > > the initial "smoke testing" to actually make some input into the > > > application and check the expected output (e.g., input: "2+2", > > > expected output: "4").

Sadly, any story in the LITE project would go completely unnoticed by the LAVA software team until it is linked to CTT so that the work can be prioritised and the relevant LAVA story created.

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.

OE/Yocto testcase

Is it possible to get data in device dictionary inside a job?

by Li, Yifan2

Hello LAVA experts, I am currently working with LAVA and was asked to find is there a way to get data from device dictionary inside a running job. Details like below: I have a device name demo-01, and its device-dictionary have one line like "{% set my_property = 'my_prop' %}". Then I have a job running on demo-01 device, and I would like to use string 'my_prop' to passed into a script during running. Is it possible to get device-dictionary data directly from job definition(Job Submitter webpage) or test definition(yaml file)? If yes, how could I do this? If not, is there any good way you would like to share to solve this problem? Thanks and Best Regards, Yifan

libzmq issue between Debian Jessie and Stretch

by Guillaume Tucker

Hi, We've hit an issue when running lava-master on Debian Jessie and lava-slave on Debian Stretch, after a few minutes the slave would stop working. After some investigation, it turned out to be due to a difference of the libzmq versions in Jessie (4.0.5+dfsg-2) and Stretch (4.2.1-4) causing some protocol errors. The line that detects the error in Stretch is: https://github.com/zeromq/libzmq/blob/7005f22726d4a6ca527f27560a0a132394fdb… This appears to be due to how the "once" counter gets written into memory and into the zmq packets: the libzmq version from Jessie uses memcpy whereas the one in Stretch calls put_uint64. As a result the byte endianness has changed from little to big, causing the packets to work until "once" reaches 255 which translates into 0xff << 56, after which it overflows to 0 and causes the error. This is not a LAVA bug as such, rather a libzmq one, but it impacts interoperability between Jessie and Stretch for LAVA so it may need to be documented or resolved somehow. We've installed the new version of libzmq onto our Jessie servers to align them with Stretch; doing this does fix the problem. Best wishes, Guillaume
