Hi, I have started trying to connect my DUT and run tests via serial. I'm not sure if it's a me issue, or a documentation issue, but I can't seem to puzzle it together. My DUT is connected to my worker via serial, and I've configured my ser2net.yaml file (docs say it's a .config, but I found no such thing) with both the provided example and something based on what was already in there. The problems arise in the job definition, and device dictionary. I've made a (pretty much) blank device template which extends base-uboot, and does nothing else. The device dictionary defines power_off_command, power_on_command, soft_reboot, and the connection_(list, commands, and tags). There is also the baud rate and console device However, I've also seen some device templates use a root device instead or alongside console device, what's the difference? Whenever I use my worker IP for the telnet command, I get connection refused, but if I use the DUT IP the connection times out after 2 minutes. I can connect to the device using minicom, so I don't think the serial connection is bad, and I have no problems using SSH on the device and other systems connected to my network. The only information I have on the device is that it's ARMv5TEJ, it has a custom kernel and runs on otherwise custom hardware. Below is my device dict: {% extends 'test-template.jinja2' %} {% set power_off_command = 'python /power.py off' %} {% set soft_reboot_command = 'reboot' %} {% set power_on_command = 'python /power.py on' %} {% set connection_list = ['uart0'] %} {% set connection_commands = {'uart0': 'telnet dispatcher01 7001'} %} {% set connection_tags = {'uart0': ['primary', 'telnet']} %} {% set console_device = 'ttyUSB0' %} {% set baud_rate = 115200 %} My questions are: - Difference between root_device and console_device in device dictionary/template? - Do I set the telnet command to use my worker IP or my DUT IP? - Is there something other than telnet I'm meant to or can use? - How am I actually meant to configure the ser2net.yaml? - How do I define the test job for serial to execute commands on the DUT?

Facing `Infrastructure error: Cannot find command '' in $PATH` error while starting the job

by sai.sathujoda＠toshiba-tsip.com

Hi all, Recently I updated device dictionary for my devices in lava server machine. I added {% set user_commands = {'start_tpm': {'do': 'cmd1', 'undo': 'cmd2' }%} in the following file /etc/lava-server/dispatcher-config/devices/qemu-01.jinja2 After updating I was successfully able to use these user defined commands in my job definitions using command action where ever i needed them. But a strange thing is happening after I made the above mentioned changes is I am unable to start the job where it is throwing Infrastructure error: Cannot find command '' in $PATH` when I use minimal boot action in my job. I cross checked this in 2 ways, 1. I removed my user command device dictionary related changes from my lava server and my job is starting and is completed successfully even if i have minimal boot action in my job. 2. I changed my boot action from ( method: minimal ) to (method: qemu , media: tmpfs ), and i retained user command device dictionary changes in my device template.. In this case also the job started and is completed successfully. So is there some conflict between adding commands to device dictionary and using minimal boot action in our job ? I am not sure how these two are related. My use-case badly requires minimal boot actions in my job as well as some user defined commands in device template. Please have a look at my job definition and run log https://lava.ciplatform.org/scheduler/job/1089996. I needed minimal boot action to finish the boot action only if i get a particular shutdown-message or else I want it to timeout and be incomplete. Can anyone please help me how to resolve this issue ?

Queries and Charts

by Daniel Jensen

Hi All I am trying to sort out using queries to make charts and I am running into two problems. 1. Even after adding conditions I can not run queries as the button is disabled. I can get around this by changing it to a live query but I would prefer to be able to use the actual button. 2. I can't view a chart. When I try to do this I just get a loading screen that won't end. According to the Console, the error is either undefined properties or functions not existing. My query selects all jobs with a test suite with a name equal to 0_smoke-tests and then my graph is Type: pass/fail, Representation: bar, X-axis attribute: none. I am wondering if these are bugs or if I am doing something wrong. If anyone can help that would be greatly appreciated Thanks Daniel

Azure DevOps repo instead of GitHub

by michael.peddie＠gallagher.com

Hi, As stated in the subject, I was wondering if it is at all possible to use a repo on Azure DevOps instead of a GitHub one. I have been using a GitHub repo thus far, and it works just fine, but I need to move my files over to DevOps. According to the docs here: https://docs.lavasoftware.org/lava/actions-test.html only git is supported at the moment, with URL and tar planned for. Would URL work for this if support came in at any point? Or would azure need its own support? Or should git work and there is something wrong with the repo URL I am using? Because the particular error I get is that the password could not be read (I'm using a PAT in the link, like I did for GitHub) Best Regards. Michael

Error Message on boot log:

by pawanKumar

Hello Team, I was trying to flash a binary on the device and run the tests on the device by using lava overlay. Board flashes successfully but while booting the device in the boot log there is a word "*** Invalid partition 3 ***" lava catches the key word and throws an error message. For the other devices it is not catching this error with the same boot log. Only on one device I'm observing this issue. Please let me know How to ignore the keyword and move on to run the tests. matched a bootloader error message: 'Invalid partition' (17) boot log: *U-Boot SPL 2022.04 (Nov 30 2023 - 20:10:15 +0000)power_bd71837_initDDRINFO: start DRAM initDDRINFO: DRAM rate 1600MTSDDRINFO:ddrphy calibration doneDDRINFO: ddrmix config doneNormal BootTrying to boot from MMC1hab fuse not enabledAuthenticate image from DDR location 0x401fcdc0...NOTICE: BL31: v2.6(release):lf-5.15.32-2.0.0-0-gc6a19b1a3-dirtyNOTICE: BL31: Built : 06:37:22, Jun 7 2022U-Boot 2022.04 (Nov 30 2023 - 20:10:15 +0000)CPU: i.MX8MMD rev1.0 1600 MHz (running at 1200 MHz)CPU: Industrial temperature grade (-40C to 105C) at 44CReset cause: PORModel: DRAM: 224 MiBboard_initCore: 61 devices, 21 uclasses, devicetree: separateMMC: FSL_SDHC: 0Loading Environment from nowhere...

How to add actions after a reboot triggered by a watchdog (for ex: in case of kernel panic) and continue the test definition

by sai.sathujoda＠toshiba-tsip.com

Hello everyone, I am trying to implement a test case scenario in which I need to confirm partition scheme, environment variables after the reboot which is triggered by the watchdog I am using. So basically I need to be able to successfully login to the image after the reboot triggered by the watchdog. It feels like the link between the test Job and the Linux image is lost after the reboot done by the watchdog. Whatever actions present after that reboot ( boot or test actions ) are not working. Below is the template of my Job definition: job details... device_type: qemu #### (timeouts) ###(priority) ##(notify, context etc.) actions - deploy images: ### firmware: ### - boot auto_login: login_prompt: "###" username: "##" password_prompt: "###" password: "##" - test: definitions: ### repository: #### metadata: ### run: steps: - swupdate -i #### - reboot ------------------------------------------------- At this stage I introduced a service which causes kernel panic during the reboot (by the command explicitly given by me above in the job). So after 'X' seconds of watchdog timeout , a second reboot is triggered by the watchdog. During that reboot done by watchdog, the kernel booted successfully, all the services were set up fine, but the test stopped at the login stage. I think it did not get the "login_prompt" and ''password_prompt" from the boot action I wrote after the above test action ( i.e after reboot done by watchdog ). - boot auto_login: login_prompt: "###" username: "##" password_prompt: "###" password: "##" So Is there a way to add boot and test actions in such a way that the test job can be continued after reboot is done by a watchdog ? Note: When I explicitly provide "reboot" in steps section in test action, then the link did not break and I was able to reboot, login and run test action steps successfully no matter how many times I wanted. This query is specifically for cases in which reboot happened out of test writer's scope. (i.e like reboot triggered by a watchdog)

Unable to detect the reboot triggered by watchdog or software updates in LAVA

by sai.sathujoda＠toshiba-tsip.com

Hello everyone, I would like to open thread of discussion to understand about LAVA test framework support for some of the use cases where I’m facing issues. While testing a reboot scenario in CIP (https://gitlab.com/cip-project/cip-core/isar-cip-core) where reboot is triggered by watchdog. LAVA is unable to do successful reboot. Following are the steps: device_type: qemu job_name: qemu x86_64 software update testing timeouts: job: minutes: 20 action: minutes: 10 actions: power-off: seconds: 60 priority: high visibility: public notify: criteria: status: finished recipients: - to: method: email email: sai.sathujoda(a)toshiba-tsip.com context: arch: x86_64 lava_test_dir: '/home/lava-%s' # ACTION BLOCK actions: - deploy: timeout: minutes: 15 to: tmpfs images: system: image_arg: '-drive file={system},discard=unmap,if=none,id=disk,format=raw -m 1G -serial mon:stdio -cpu qemu64 -smp 4 -machine q35,accel=tcg -global ICH9-LPC.noreboot=off -device ide-hd,drive=disk -nographic' url: ######.wic.xz compression: xz firmware: image_arg: '-drive if=pflash,format=raw,unit=0,readonly=on,file={firmware}' url: ###### # BOOT BLOCK - boot: timeout: minutes: 5 method: qemu media: tmpfs prompts: ["root@demo:~#"] auto_login: login_prompt: "demo login:" username: "root" password_prompt: "Password:" password: "root" # TEST_BLOCK - test: timeout: minutes: 5 definitions: - repository: metadata: format: Lava-Test Test Definition 1.0 name: sample-test description: "check reboot version" run: steps: - lava-test-case uname --shell uname -a - cd /home - wget --no-check-certificate #### - lsblk - swupdate -i cip-core-* - reboot from: inline name: sample-test-1 path: inline/sample-test.yaml - boot: timeout: minutes: 5 method: qemu media: tmpfs prompts: ["root@demo:"] auto_login: login_prompt: "demo login:" username: "root" password_prompt: "Password:" password: "root" - test: timeout: minutes: 5 definitions: - repository: metadata: format: Lava-Test Test Definition 1.0 name: sample-test description: "check partition switch" run: steps: - lsblk from: inline name: sample-test-2 path: inline/sample-test.yaml context: arch: x86_64 lava_test_results_dir: '/home/lava-%s' A reboot is triggered by watchdog following the reboot done in the test action due to failed case. The reboot triggered by watchdog failed with timeout error at login stage which can be interpreted that last boot action in the above job definition failed to give the assigned login prompts. I have already received some opinion about this from LAVA users community that LAVA does not support the board being rebooted outside it’s control ( whether by a watchdog or a package ). However, CIP extensively uses LAVA as test framework to regressively perform many kinds of tests on CIP supported hardware. Testing the watchdog is an important use case in CIP. Since LAVA is supposed to be test framework which can help to test many type of hardware. We as CIP project member would like to understand LAVA community future plan to support this use case. Thanks and Regards, Sai Ashrith

lava-publisher not publishing

by Milosz Wasilewski

Hi, During last couple of weeks I had at least 2 occasions when lava-publisher stopped working. There is nothing in the logs that suggest a failure. The only symptom was that no events were published. Restarting the service fixes the issue. Is this a known bug? I'm running 2023.10 release. Best Regards, Milosz

How to fail a test run on kernel warnings that happen after the boot action?

by Florian Bezdeka

Hi all, I'm basically repeating [1] here as there was no reaction for some months now. Maybe I used the wrong communication channel, let's see... We have a testsuite that is able to trigger a RCU WARNING inside the Linux kernel. My expectation was that whenever a kernel warning / oops / call stack dump / ... occurs the LAVA job is marked as "failed". This assumption seems to be wrong. It took some time to realize that we have a real problem as manual inspection of test logs only happens from time to time. After scanning the code my understanding is that the output of the connection (serial connection in my case) is only parsed during kernel boot (until the login action takes over). That is not sufficient for detecting problems that happen during test execution. Is there a way to scan the full log for the same patterns that are used by the boot action? If so, how to configure that? Whenever a kernel problem occurs my test run should be marked as "failed". Any ideas? Did I overlook something? Best regards, Florian [1] https://git.lavasoftware.org/lava/lava/-/issues/576
