Hi, I have a board with 4 uarts connected to a lava worker via ser2net. LAVA is giving me some strange results when I try to use two uarts (uart0 and uart2) in the same testcase. The results are not consistent. Sometimes it works, but most of the time it gives an error: KeyError: 'uart2' At the end of the job, LAVA prints: LAVABug: This is probably a bug in LAVA, please report it.error_type: Bug error_msg: 'uart2' case: job result: fail definition: lava <http://lava-master.sw.nxp.com/results/testcase/16283386> ---- The connection parts of the device definition are: % set connection_list = ['uart0', 'uart1', 'uart2', 'uart3'] %} {% set connection_tags = {'uart0': ['primary', 'telnet']} %} {% set connection_commands = {'uart0': 'telnet localhost 7001', 'uart1': 'telnet localhost 7002', 'uart2': 'telnet localhost 7003', 'uart3': 'telnet localhost 7004'} %} The job uses two boots; one primary to boot non-POSIX to uboot, then it switches to 'uart2' to access another processor. The job seems to work fine if I define only two uarts: % set connection_list = ['uart0', 'uart1'] %} {% set connection_tags = {'uart0': ['primary', 'telnet']} %} {% set connection_commands = {'uart0': 'telnet localhost 7001', 'uart1': 'telnet localhost 7003 } %} Thank you, Nick

VTS does not start because of the adb

by George Nistor

Hello Lava users, Thanks to Tim Jaaks for previous problem I reported. I managed to configure default external shared folder for the lava lxc container. However, I try to run VTS from Lava but after displaying initial string with VTS I get an error saying adb server could not start. I have tried restart, no success. The adb seems to be installed in the container. Does anyone know how to solve this error? + ./vts-tradefed Android Vendor Test Suite 9.0_R2 (eng.l4b.20190906.094644) Use \"help\" or \"help all\" to get more information on running commands. 10-15 13:45:22 E/adb: ADB server didn't ACK 10-15 13:45:22 E/ddms: 'adb start-server' failed -- run manually if necessary 10-15 13:45:22 E/adb: * failed to start daemon * 10-15 13:45:22 E/adb: error: cannot connect to daemon [udev_trigger-lxc-hikey-test-214-13:45:29] device /dev/bus/usb/001/005 added The adb is put in tlcx deploy actions: - deploy: namespace: tlxc timeout: minutes: 5 to: lxc packages: - adb - fastboot - wget - unzip - default-jre os: debian george

is lxc shared folder possible?

by George Nistor

Hi Lava users, For my test, instead of downloading android-vts.zip archive from git I decided it will be used from a location on a machine which hosts Lava. The question is: Is it possible to make like a shared folder for the lxc container lava has created? Or is any other way to access directly from the lxc container a folder on the host machine? If so, how should be done? george

Re: [Lava-users] lava job without any flashing on a real device

by George Nistor

Yes, In my case the only way I could make lava to see the fastboot device was via running pre-power-command, and I run a script (I customized device descriptor to run a this script as pre-power-command) which does: 1. Power Off Wait 5s 2.Power On Wait 30s 3. Login as root Wait 5s 4. echo reboot bootloader. # make it go in fastboot mode Immediately after this script runs, the udev rule is triggered and device id added (seen from Lava). Otherwise the reboot does not work for me. The line: nice lxc-attach -n lxc-hikey-test-186 -- fastboot -s xxxxxxx reboot gives timeout. Because the device is not seen. To make the job work without any flashing I removed the - deploy section which does flashing entirely For my case: I have added to boot this section protocols: lava-lxc: - action: fastboot-boot request: pre-power-command timeout: minutes: 5 george The full job I cannot post due to company policy with confidentiality on projects. -----Original Message----- From: Milosz Wasilewski <milosz.wasilewski(a)linaro.org> Sent: luni, 14 octombrie 2019 15:58 To: George Nistor <george.n(a)l4b-software.com> Subject: Re: lava job without any flashing on a real device Could you send the question to ML?

Comparing output within a job execution between reboots

by Diego Russo

Hello, I have a job with the following flow: 1) deploy the DUT 2) boot the DUT 3) while booting, I need to capture a string: it is the version/timestamp of BL2. For example: NOTICE: BL2: v2.1(release):v2.1-232-g89a4d26-dirty NOTICE: BL2: Built : 04:06:44, Sep 25 2019 4) perform an update of the BL2 5) reboot the device 6) while booting the second time, I need to capture again the version/timestamp 7) Compare the 2 strings: if they are different, the test passes. How can I do 3) 6) and 7) with LAVA? Thanks -- Diego Russo | Staff Software Engineer | Mbed Linux OS ARM Ltd.

Lava does not do DUT login

by George Nistor

Hello Lava users, I have a Lava job, with the following section: - boot: namespace: target prompts: - 'root@xxxxx:~#' auto_login: login_prompt: 'xxxxx login:' username: root timeout: minutes: 5 method: fastboot and Lava does not complete with 'root' to do autologin. After 5 mins it give me timeout autologin. Even if I run the job and waited till the login prompt comes as output in Lava and do a echo 'root' > /dev/ttyUSB2 still Lava detects timeout autologin. (even if the devices successfully logs in - I have sent the string 'root' 2 times from the terminal).

ODROID-N2: Installation & configuration help

by Malcolm Brooks

Hi All, I am installing an ODROID-N2 board into our LAVA setup. I see that there is support for ODROID-X2 and ODROID-XU3 in the LAVA codebase, but no mention of ODROID-N2. Before I start, I wanted to know if anyone has successfully installed an ODROID-N2 in LAVA? Does it work with the existing support added for the other variants? Are there any specific bits of hardware I will need to use and/or device dictionary settings I need to ensure are set before I can get the board up and running?

lava-server-gunicorn worker crashes

by Dean Birch

Hi, We've recently had an issue with our LAVA instance (version 2019.05.post1), where a long running LAVA job which had a large log file led to instabilities when serving web content. The large job was seemingly causing lava-server-gunicorn workers to use up more memory than was available, leading to workers crashing and then restarting. This led to all the workers processing the large jobs most of the time, while other requests would only be served once the workers restarted. This led to the webpages being served extremely slowly and lavacli usage timing out (if a larger timeout was not set). We had "LOG_SIZE_LIMIT": 3 set in our /etc/lava-server/settings.conf, and we did have the message on that job page for "*This log file is too large to view"*, but it seems that some requests were still attempting to process some aspect of the job causing these worker crashes. Is there any other settings that might need to be set in order to cope with long running jobs with large log files that might help with this situation? Before we look into this any further, does anyone know if this is fixed with a newer version of LAVA? Has anyone had any similar issues with their instances? Thanks, Dean
