Alternate Bank booting support on NXP Layerscape boards

by Sahil Malhotra

Hi, We are working on integrating NXP Layerscape boards in LAVA. On Layerscape boards, we have a mechanism of having multiple banks. This is done mainly to protect board from getting bricked if wrong images gets flashed on board. Board is set to boot from a Bank 1 by default (controlled by switches). Now you use this bank also to flash your images, but in case the images are corrupt, board will get bricked and you will need to connect JTAG to recover the board. So here concept of Alternate Bank boot comes to help. By default board boots from Bank 1, but we will not flash the images on Bank 1, instead we will flash images on Bank 2. After flashing the images, we will boot from Bank 2 with a certain command on u-boot "qixis_reset altbank". With this command, Board boots from the Bank 2 and now we can boot up kernel on board. Since in this case, we have flashed the images on Bank 2 and even if images are corrupt, Bank 2 will get bricked, but since we have set board to boot from Bank 1 by default, Board will still be usable and you can flash the correct images on Bank 2 and get that working. So this was the concept and why we are using it. Now when we try to replicate the same behavior with LAVA, we are facing some issues. When we issue command "qixis_reset altbank" on u-boot, it just prints "=>", which lava takes as a success and issue next command and then starts waiting for the "Starting Kernel", which will not happen. Infact what should happen is that, after "qixis_reset altbank" is issued, lava should wait for some time and let board boot from Bank 2 (On Bank 2 board again will boot the u-boot only). and wait for "Hit Any key to stop autoboot" and then interrupt the board. Here is job.yaml for your reference. https://git.lavasoftware.org/lava/lava/uploads/2a530894990eca6c69648e6ad637… Please help me on this, how can i achieve this way of booting the board. Thanks Sahil Malhotra

Error of results.get_testcase_results_yaml

by Larry Shen

Hi, guys, When I call `results.get_testcase_results_yaml`, there is a small probability that I will get the error: Post https://xiaotian:***@lava.sw.nxp.com/RPC2: EOF What does "EOF" here mean, what could be the possible root cause? Thanks.

Any method to directly get device name from test shell?

by Larry Shen

Hi, guys, In lava, if we define e.g. "imx8mm-evk-sh01.jinja2" device dict, and run a job on this device, if possible we could get the name (imx8mm-evk-sh01) of this device directly in test shell? I don't want to define environment again and again in jinja2 file something like "{% set environment = {'DEVICE_NAME': " imx8mm-evk-sh01"} %}"..., there possible fault & mismatch when define this. Thanks.

How to exit job in advance.

by Larry Shen

Hi, guys, We have a scenario like next: action: - test definitions: - from: inline name: test1 - test definitions: - from: inline name: test2 For some reasons, we have to use 2 tests here, everything is ok now. But, if `test1`, that is ` /lava-3102/0/tests/0_test1/run.sh` finished with non-zero, from web we can see the suite fail. Then, we want to exit the job at once, not continue to run `test2`. If possible here? Regards, Larry

Set boot settings with x86 / PXE

by Fabiano Ferronato

Hi everybody, I'm trying to figure out how to set boot parameters (nfsroot) for a x86 board (Intel NUC10 ). >From this job definition I understand it's possible using iPXE: https://lkft.validation.linaro.org/scheduler/job/2959364/definition But I can't understand what interface is being used to get terminal output and remote control: https://lkft.validation.linaro.org/scheduler/device/x86-01/devicedict Look's like is using UART, I'm not sure I can get terminal console on boot time on my board (NUC). The options I can get from the information found are the following (please add any corrections or suggestions): 1) iPXE + terminal console: PXE alone can't get nfsroot settings dynamically. PXE + iPXE should be added to the chain and LAVA should have access to terminal console. 2) iPXE + environment variables: LAVA sets environment variables and PXE + iPXE gets nfsroot settings from environment variables. No terminal console needed. 3) PXE + static folder: LAVA fetches and extract rootfs always to the same folder. PXE reads static configuration file. 4) PXE + dynamic folder: LAVA sets the nfsroot folder name directly on the PXE configuration file (file is machine specific). 5) PXE + INITRAMFS: fetches root file system from file server and extracts to memory. Let me know your thoughts! Best Regards Fabiano

Difference of next 2 docker options.

by Hedy Lamarr

Dear, I'm a little confused about the next 2 options: a) https://lava.readthedocs.io/en/latest/user/advanced-tutorials/running-arbit… b) https://lava.readthedocs.io/en/latest/admin/basic-tutorials/device-setup/do… It seems they both run a docker container on pc, what's the difference between them? Could one replace another? What I expect to get is something like: for xx scenario, you need to use option a, while for xxx scenario, you need to use option b. Thanks, Hedy Lamarr

Providing Arguments from Job to Test Shell (definition?)

by Westermann, Oliver

Hey, We're using lava to test multiple of our devices. While most tests are similar ("does the device still have a working ethernet connection"), some slightly differ. For example a device might have LEDs 1-3, another the LEDs 1-5. Today I save multiple test shell definitions test1-device1.yaml, test1-device2.yaml, ..., which all just differ by providing "device1", "device2", ... in an argument to the actual test script, so the run: section looks like this: run: steps: - cd ./testdir/ - ./run_test.py device1 I would like to get rid of the two, separate .yaml files and only have a `./run_test.py ${device}` or similar. Is there any way to provide a variable from the job definition to the test shell definition? Or are things like the device type set in the environment so I could access them? Best regards, Olli

Device status not correct.

by Hedy Lamarr

Dear all, I don't know what operation I have done, but when a device does not have any running job, I still see the device is in running status. I just saw this 1 time, maybe it's a bug or just bad luck. Anyway, I can't reproduce it on other devices, so it's ok. But, could you teach me to reset the status to make the device work again? Do we have some method to reset the status from "Running" to "Idle", or any api if we don't have an interface on the UI? [image: image.png] Thanks, Hedy Lamarr
