Re: [Lava-users] Server returning wrong job id

by Fabiano Ferronato

Hi Milosz, Please take a look at the first message of this thread. There are 2 different information for this error. First, this COMMA error happens when I'm trying to access the URL (LAVA WebU), manually inserting the job_id in a browser, and not through the code. Second, the previous code is returning: lavac.server.NoSuchJob: No such job: 68271.0 Even though this job_id is been returned by the LAVA server.

Fastboot device Connection

by Ilya Fedusiv

Hi! I'm using lava from debian stretch. I try flash image by fastboot. At that step job just stuck and util timeout of 10 minutes. nice fastboot -s '261a1c5d' flash persist /var/lib/lava/dispatcher/tmp/15/fastboot-deploy-7xj200yq/persist/persist.ext4 If run command from terminal fastboot -s 261a1c5d flash persist /tmp/persist.ext4 device is flashed in 3 seconds It looks like, that LAVA doesnt see my device. Job desc : https://pastebin.com/ZNeS71Ev Device desc: https://pastebin.com/rYRyEnjy Job log : https://pastebin.com/fH0u3bUb I know, that for fastboot better to work with lxc. I also tried with lxc. And it stuck on the same place. Job log with lxc : https://pastebin.com/RnZLNfvN Ilya

Test Job bulk canceling from admin does not work in 2019.09

by Stevan Radakovic

We've just discovered that the bulk canceling of test jobs in LAVA admin does not work. Issue in gitlab: https://git.lavasoftware.org/lava/lava/issues/310 We will fix this asap and roll it out with next release or hotfix, whichever comes first. A workaround is to either use XMLRPC API or cancel jobs one at a time. Cheers, -- Stevan Radaković | LAVA Engineer Linaro.org <www.linaro.org> │ Open source software for ARM SoCs

Power time measurements

by Denis HUMEAU

Dear Lava users, I'm looking for a way to measure, with Lava, time measurements between some power modes. Let's say the time between two messages : - Standby exit trigger - Actual standby exit from the kernel The constraint is that we can't rely on kernel timestamps (frozen during standby) and the power process implies not only kernel but also boot stages. We can only rely on the time spent between two specific messages in the console. Basically, if it was done without Lava, we'd use a tool like grabserial. Do you have any clue on what can be done? Best regards,

500 Internal Server Error

by Ilya Fedusiv

Hi! Problem, that I'm receiving Internal Server Error Error log of django : https://pastebin.com/9dxTi0nm Log of apache : https://pastebin.com/SSwyHymT I've started working with LAVA. I installed on VirtualBox Debian stretch, as recommended. I want lava-server lava-master lava-slave on one machine and work locally. I provided next step for installing LAVA: Add this lines to /etc/apt/sources.list deb http://deb.debian.org/debian stretch-backports main deb https://apt.lavasoftware.org/release stretch-backports main root# wget https://apt.lavasoftware.org/lavasoftware.key.asc root# apt-key add lavasoftware.key.asc root# apt-get update root# apt -t stretch-backports install lava-server root# a2dissite 000-default root# a2enmod proxy root# a2enmod proxy_http root# a2ensite lava-server.conf root# service apache2 restart After that I changed some parameters as written here : https://validation.linaro.org/static/docs/v2/installing_on_debian.html#usin… to run locally I checked variables value http://54.68.224.33/static/docs/v2/pipeline-debug.html#displaying-current-s… It is similar to what I set up. root# lava-server manage check --deploy ?: (security.W012) SESSION_COOKIE_SECURE is not set to True. Using a secure-only session cookie makes it more difficult for network traffic sniffers to hijack user sessions. ?: (security.W016) You have 'django.middleware.csrf.CsrfViewMiddleware' in your MIDDLEWARE, but you have not set CSRF_COOKIE_SECURE to True. Using a secure-only CSRF cookie makes it more difficult for network traffic sniffers to steal the CSRF token. I've read that mailing list post: https://lists.lavasoftware.org/pipermail/lava-users/2018-March/000884.html So I download http://cdn-fastly.deb.debian.org/debian/pool/main/d/django-tables/python3-d… and dpkg -i to downgrade python3-django-tables2 restart everything. This didnt helped. Ilya.

Multinode job: how can I assure that all devices are on the same worker?

by Tim Jaacks

Hello again, I have several test cases where we use LAVA multinode to test hardware and software interfaces externally. E.g. we have an SFTP server running on our DUT. In order to test that, we submit a test using two nodes: 1. The DUT 2. An LXC container The LXC device connects to the DUT via SFTP and uploads a file. Both sides determine the MD5 sum and the DUT compares them. This works as long as both the DUT and the LXC device are in the same network (or at least can reach each other via the network). Now there are more test cases which require additional hardware connections between the worker and the DUT, e.g. a serial interface test. The serial interface on the DUT is connected via an RS232-USB converter to the worker. The LXC can access this converter and send or receive data from the serial interface. This works as long as the LXC is running on the expected worker the serial interface of the DUT is connected to. As we are growing our lab, we will add more workers to our setup. There will be LXC devices on all of the workers. When submitting such a multinode job, which relies on hardware connections between the DUT and the worker, how can I make sure that the LXC part of the job is scheduled on an LXC device on the correct worker?

UART connection parameters

by Dupont, Louis [2]

Hi, I'm looking into LAVA and I figured I'd give it a try by flashing a frdm-k64f MCU board and parse its output (the board behaves as a USB to UART adapter through /dev/ttyACM0 at 115200bps). I created the board instance as: {% extends 'frdm-k64f.jinja2' %} {% set board_id = '0240000048824e45004a700add89001a8761000097969900' %} {% set usb_mass_device = '/dev/disk/by-id/usb-MBED_VFS_0240000048824e45004a700add89001a8761000097969900-0:0' %} I'm able to launch a job (frdm-k64f.job) but LAVA complains and returns: Invalid job data: ["Invalid device configuration - missing 'commands'"] So I went looking for an example and found this<https://git.lavasoftware.org/fabo/lava/blob/bc44750733f57de09909f45ba7e65fa…> which defines something called connection_commands as: {% set connection_commands = {'usb0': 'telnet lab-slave-0 7115'} %} Based on the documentation<https://docs.lavasoftware.org/lava/connections.html> I'm under the impression that the slave/dispatcher is expected to momentarily open a telnet server on port 7115 and forward the output of the serial port through that server to be retrieved by a client implemented by the master. If I match the example the dispatcher flashes the board, but a telnet server is never launched on the slave. It's not surprising as at no point did I specify a tty or a baud rate for the dispatcher to connect to the board in order and launch something like: socat TCP-LISTEN:7115,fork,reuseaddr FILE:/dev/ttyACM0,b115200,raw When I sit on the slave and manually launch the command the master successfully connects to TCP port 7115. Problem is it does so after the board outputted its results (and obviously it's not the right way to do it). So I have 3 questions: * How should a UART connection be specified (/dev/ttyACM0, 115200bps) to LAVA? * Once the UART connection specified, will the dispatcher buffer the board's output until it is retrieved by the master? * Why does LAVA rely on a telnet channel instead of the existing zmq channel to forward the output of the board from the slave to the master? Thanks

DUT in recovery mode under LAVA

by Diego Russo

Hello, We have few device types in our LAVA instance that use ums mechanism to be deployed. This has worked well so far but we have now the need to test secure boot flow (BL1, BL2...) and we cannot rely anymore in u-boot for deploying them. Assuming we have the HW in place to put the DUT in recovery mode, how can we achieve this via LAVA? Do you have an existent example where you automate the recovery mode of a board?
