UART connection issue with LAVA

by Nagendra Singamsetti

Hi, The Renesas board I am using behaves as a USB to UART adapter through /dev/ttyACM0 at 115200bps. Created the board instance in device dictionary file as: {% extends 'rza1h.jinja2' %} {% set board_id = '0000000000001' %} {% set console_device = 'ttyACM0' %} {% set baud_rate = baud_rate|default(115200) %} {% set usb_mass_device = '/dev/serial/by-id/usb-Renesas_Electronics_Corporation_Renesas_RSK_USB_Serial_Port_0000000000001-if00' %} {% set connection_list = ['usb0'] %} {% set connection_tags = {'usb0': ['primary', 'telnet']} %} {% set connection_commands = {'usb0': 'telnet localhost 2000'} %} With the above configuration, Dispatcher(Remote worker) flashes the board through JLink.And I can see flashing log in the Job console. But Even i specified the UART connection like (/dev/ttyACM0, 115200bps). I am not getting the u-boot logs on /dev/ttyACM0. Did i miss any other configuration to add in device dictionary???. Manaually, I can able to see uboot prints on the console through minicom with /dev/ttyACM0 with 115200bps. Attaching logs for reference. Thanks Regards Nagendra S

Fwd: [EXT] Test jobs to boot the targets through trace32

About pdu script.

by Peter Lucas

Sorry, I missed title, send again. Hello, Milosz, Another question: I see your documentation suggest to use pdudaemon. But I had a look for you validation lava lab: https://validation.linaro.org/scheduler/device/hi6220-hikey-r2-02/devicedict, I see you use /usr/local/lab-scripts/snmp_pdu_control I want to know why your lab not use the one which you suggest? I had a look for pdudaemon, found it won't wait there until PDU operation finish. Will this have any issue? Will next logic start before the pdu really finish the operation?

Test jobs to boot the targets through trace32

Question about serial.

by Peter Lucas

Dear Sir/Madam, I'm new to LAVA. I'm still in initial stage to use lava in our farm. I use customized board with Qualcomm's chip. Recently I met a question, a very simple job, sometimes when I start to operate uboot, the serial have chance to be closed. They I set retry in lava job, let it retry a lots of times, but looks never successfully open the serial again. But, after job finish, I quickly open the serial in manual, it's ok! I search your code a lot, and found in shell.py there is one comments, I want to know is this the reason that I failed to retry for serial? When will you fix it? *# FIXME: deliberately closing the connection (and starting a new one) needs to be supported.* *Cheers,* *Peter*

Docker device basic setup

by Saheer Babu

Hi Lava folks, I am new to LAVA and trying to get some basic understand of lava. I am facing issues while I trying to set up a docker device in lava following the doc: https://lava.readthedocs.io/en/latest/admin/basic-tutorials/instance/instal… Steps followed: 1. I have installed Debian VM on my mac book pro. 2. Installed lava: https://lava.readthedocs.io/en/latest/admin/basic-tutorials/instance/instal… * Enabled lava site in apache “Production releases” https://docs.lavasoftware.org/lava/installing_on_debian.html (Btw, this step seems to be missing) * Config like “ALLOW_HOSTS<https://docs.lavasoftware.org/lava/advanced-installation.html?highlight=all…>”, CSRF etc: (a * Created one super user: https://lava.readthedocs.io/en/latest/admin/basic-tutorials/instance/config… * Created a token (for lavacli): sudo lava-server manage tokens add --user root 1. Setup docker device for running tests: https://lava.readthedocs.io/en/latest/admin/basic-tutorials/device-setup/do… ( I am following command line using lava-cli) * $LAVACLI device-types add docker * $LAVACLI devices add --type docker --worker buster.localdomain docker01 * $LAVACLI devices dict set docker01 test.jinja2 (test.jinja2 contains {% extend "docker.jinja2" %} ) * $LAVACLI devices update --health UNKNOWN docker01 After step “3”, I have the following error: “Configuration Error: missing or invalid template.” I am assuming there is some pre-condition I am not meeting for docker device. How can I get some more debug information on this? Can you help? Cheers, Saheer Babu IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

Need help for 2020.05 release.

by Larry Shen

Hi, We have a problem here needs your help, as it's critical to us, could you give some suggestion? Thanks in advance. You know, we submit a MR here about reset shell: https://git.lavasoftware.org/lava/lava/-/merge_requests/1023 It's nearly compatible from 2018.11 to 2020.04 release when we patch it in local, the only changes I remember is once upon a time you changed all "internal_pipeline" to "pipeline", so we had to follow the new name. But in yesterday's 2020.05 release, I saw this commit: https://git.lavasoftware.org/lava/lava/-/commit/eefeef1864cc055c48215169b61… In this commit, the test action no longer been added as before like next: def __init__(self, parent, parameters): super().__init__(parent) self.action = TestShellRetry() self.action.job = self.job self.action.section = self.action_type parent.add_action(self.action, parameters) It becomes next: @classmethod def action(cls, parameters): return TestShellRetry() Correspondingly, in parse.py, it becomes from next: action(pipeline, parameters) to next: action = cls.action(parameters) That means "parent pipeline" no longer been passed to next level pipeline, parse.py will responsible for low level action inject into pipeline. Above change is the key issue we encountered as in our "ResetTestShell" we need to reuse the parameters of "Boot" in same namespace, we need it to operate UBoot & Login again after device reset, like next: def __init__(self, parent, parameters): super().__init__(parent) boot_action_para = None for per_action in parent.actions: if per_action.parameters["namespace"] == parameters["namespace"]: if per_action.__class__.__base__.__name__ == "BootAction": boot_action_para = per_action.parameters self.action = TestShellLoop(boot_action_para) self.action.job = self.job self.action.section = self.action_type parent.add_action(self.action, parameters) You see we could get the "Boot" action from its parent action, thus we could get the boot action's parameters defined in job.yaml, then reconstruct the boot action, inject it as a internal action to our own test action. But now, we can't do it as parent action no longer be passed to low level action... Could you give me some suggestion on it, if any other way I could get the parameters of boot action when I'm in test action? Thanks again. Regards, Larry
