Hello Lava Users,
The target on which I am trying to run tests from LAVA has # prompt after
login.
As specified in Documentation
https://lava.collabora.co.uk/static/docs/v2/actions-boot.html?highlight=pro…
- boot:
prompts:
# escape the brackets to ensure that the prompt does not match
# kernel debug lines which may mention initramfs
- '\(initramfs\)'
in the job definition I am including -
boot:
.....
failure_retry: 4
prompts:
- '\(# \)'
But in the job execution log getting "*auto-login-action: Wait for
prompt ['\\(# \\)', 'Login incorrect', 'Login timed out'] (timeout
00:07:52)*".
Also if we want to debug while running the job which will be the best
possible approach to follow.
In the Documentation got information on "Debugging Django issues"
which states two settings are required
in/etc/lava-server/settings.conf
- "DEBUG": true,
- "USE_DEBUG_TOOLBAR": true,
Thanks,
Hemanth.
Hello Denis,
in the timeouts dictionary, you can specify a connections dictionary.
So something like this should work:
timeouts:
connections:
overlay-unpack:
minutes: 10
See
https://docs.lavasoftware.org/lava/actions-timeout.html#connection-timeout

Hi,
I'm trying to write a test definition that contains a repeat block (boot / test) as described in the help section.
However the repeat block gives me the syntax error:
"Invalid definition: extra keys not allowed @ data['actions'][2]['repeat']"
I then tried using https://git.lavasoftware.org/lava/lava/blob/master/lava_dispatcher/tests/sa… as an example and I get the same error message with the repeat.
Is this something that is expected to work? I would like to use repeat blocks for some soak tests that I am writing.
Pete

Hello,
I am working with Denis HUMEAU for STMicroelectronics.
I have a problem to perform several reboot with LAVA job when I am using an image with requested login.
I do not understand why 'root' login is sent to device under test when the prompt is received (lines 941, 942, 943, 944 in job_43624.log file). 'root' login should be sent only when a 'login_prompt' is received (like in lines 696, 697, 698, 699, 701, 702 in job_43624.log file).
Could you help me to solve this problem, please ?
Regards,

Hello everyone,
I have the following LAVA setup:
LAVA server - 1 LAVA worker - 16 DUTs
The LAVA server and the LAVA worker are located in my company network (172.20.0.0/16).
The DUTs are connected to the LAVA worker in a local network (192.168.20.0/24).
Thus, the DUTs are not accessible from outside the worker.
What is a good way to allow for hacking sessions to a DUT (let's say 192.168.20.247) from the company network?
I can think of the following solutions:
1. Use SSH forwarding on lava-worker:
ssh -g -L 50000:localhost:22 -N root(a)192.168.20.247
2. Forward the SSH port via netcat on lava-worker:
nc -l -p 50000 -c "nc 192.168.20.247 22"
3. Forward the SSH port via iptables on lava-worker:
iptables -t nat -A PREROUTING -p tcp --dport 50000 -j DNAT --to 192.168.20.247:22
All of these make the device accessible via "ssh -p 50000 root@lava-worker" from the company network. So far, so good.
However, in an ideal world this forwarding would be active only during the hacking session, so that in normal test jobs the DUT is not accessible.
Is there a way to achieve this? Does anyone have experience with such a scenario? How do you handle DUT access for hacking sessions?
Mit freundlichen Grüßen / Best regards

Hello LAVA experts,
I need your help for a more complex test we would need to run.
We'd like to test a gateway node that talks to remote sensors.
* the gateway node is a Cortex-A like (E.g.: RPi3) board
* sensors might be a mixture of Cortex-M (non-Linux) and Cortex-A (Linux) devices
* communication between the gateway node and sensors might happen with different protocols: bluetooth, wifi, lora, zigbee.
* besides the gateway node, we need to control every sensor and be able to provision and to power cycle them.
We are pretty confident on running tests on single boards (with and without interaction with LXC containers) but as the above example is more complex we need some guidance on how this can be achieved with LAVA.
The main question mark we have is how LAVA interacts with Cortex-M devices, especially for their deployment.
Does anyone of you have a similar scenario? What are the main challenges? How complicated and/or robust to run something similar with LAVA?
Can you point us to documentation, examples?
Any help is very much appreciated.
Thanks!

Hello,
We have some tests that are currently expected to fail, and should then become passes once the implementation of the feature is complete.
Is this something LAVA results can support? As far as I can see the result can be pass/fail/skip (and possibly unknown).
Suggestions welcome.
Thanks.
Pete

Hello,
we are trying to add external interfaces on the worker to connect with the DUTs, for example a 4-port USB-to-RS232 converter. Our DUTs have multiple RS232 ports which shall be tested using this remote interface.
We have already figured out how to integrate this hardware into the LAVA environment, so that it can be used within the LAVA LXC (using static_info in the device dictionary, resulting in the four /dev/ttyUSB* devices being visible there).
First question: We need multiple of these converters attached to the worker. How do we integrate these into LAVA? They all have the same board_id, vendor_id and product_id. If I specify the board_id in the device dictionary multiple times, the device is still added only once.
Second question: We need a way to specify to which of the /dev/ttyUSB* ports a certain RS232 port of the DUT is connected. The place where I would assume to put such information is the device dictionary. But how can we access this information within a LAVA test shell?
The documentation specifies some similar mechanism for energy probes:
https://validation.linaro.org/static/docs/v2/admin-lxc-deploy.html?highligh…
It says "Devices which are not directly attached to the worker can also be supported, for example energy probes which communicate over the network".
As far as I can tell from the code, though, this seems to be a hard-coded feature without any possibility of adding other custom hardware. Is that correct?
If yes, why isn't there a generic mechanism to supply static_info from the device dictionary in the LAVA test shell? Or is there?
How can we implement our scenario described above using LAVA?

After getting stats on my setup robustness, the step forward is have a complete view on the lava errors we meet in incomplete jobs.
>From what I see in incomplete jobs, my intention is to query on test suite lava and the name "job".
In the query builder, if I use test suite as condition model, I can't use the job field name.
Do you have any advice on how to proceed?
Denis
