Hello,
we have the need to perform tests that require reboots of the DUT between their executions. Few examples are to check rootfs upgrades or to check configurations changes to persist .
I have few questions:
- Does LAVA support those cases?
This is board dependent and, in some cases, deployment method dependent as well. TFTP deployments, for example, will need a redeployment.
For the deploy action I have uboot-ums and a tftp.
I made some progress with this. Apparently there is a “minimal" boot actiom which is not documented.
https://git.lavasoftware.org/lava/lava/blob/master/lava_dispatcher/actions/b...
It connects and reset the DUT. This is exactly what I needed.
We encountered another problem though.
My pipeline is something like this
- boot: method: u-boot commands: ums auto_login: login_prompt: '(.*) login:' username: 'root' prompts: - 'root@(.*):~#' timeout: minutes: 50
- test: timeout: minutes: 50 definitions: … … …
- boot: method: minimal auto_login: login_prompt: '(.*) login:' username: 'root' prompts: - 'root@(.*):~#' timeout: minutes: 50
When it boots the second time for some reasons it matches straightaway the first prompt. Here a copy/paste of the log

The workaround I’m implementing is to change the prompt before the reboot and wait for the modified prompt afterwards but for some reason this doesn’t work. Basically I create a .profile which modifies PS1.
LAVA gets to a point where it sends the username but then it doesn’t match the prompt.

This is what I have in ser2net if I boot the board manually
Mbed Linux OS mbl-os-0.5.120 mbed-linux-os-8881 /dev/ttymxc0
mbed-linux-os-8881 login: root root@mbed-linux-os-8881-second-stage:~$
Which looks OK to me.
Any idea why the second prompt matching is not working?
Cheers
- If yes, does LAVA support multiple reboots?
Specify the actions in the test job actions list:
deploy, boot, test, boot, test
I’ve just tried but after the execution of the test, when it goes in to boot again, it redeploys the board again. I just want a simple reboot of the board.
- If yes, how can I write tests in order to run different sets of tests at any boot.
- Example: 1) do an upgrade 2) reboot the device 3) Check if the upgrade was successful
Specify a boot action to control how the device gets rebooted.
That’s a good point. I need to reboot WaRP7 and a RPi3 boards. And if I replicate the boot section it will deploy again the boardd. How can I skip the redeployment
- How can I structure my pipeline?
The hikey 6220 health check deploys two different systems, rebooting appropriately: https://staging.validation.linaro.org/scheduler/job/247930/definition
