Hi Larry,

Using your suggestions I was able to get uuu up and running. Thank you!

I have a follow question. The uuu tool accepts a url to a uuu package hosted on a remote server.

Can I use a single url to a uuu package in my job description yaml file instead of having to individually describe the files? (As shown below)

- deploy: to: uuu images: boot: url: file:///home/davis/uuu/imx-boot-64.bin system : url: file:///home/davis/uuu/sd.img

Secondly, I wish to use a raspberry as a lava dispatcher so I was wondering if a cross compiled version of uuu for armhf is available?

Thanks,

Davis

Back to your question, I guess you define a customized "imx8m" device type, what we used is e.g. imx8mp-ab2 or others: https://git.lavasoftware.org/lava/lava/-/blob/master/etc/dispatcher-config/d...

It extends from imx8m-common, and finally extends from base-uboot.jinja2: https://git.lavasoftware.org/lava/lava/-/blob/master/etc/dispatcher-config/d..., in this file, we define "uuu" keyword.

So if you want to define your own devicetypes, you will have to somehow define your own device types extends from "base-uboot.jinja2", or try to use NXP upstreamed device types.

Hello,

I received an error message when using the 'uuu' boot action on v2021.09. I tried poking around through the lava source but I'm still fairly new to the repo so I'm a bit stumped. Any comments or suggestions would be greatly appreciated.

Thank you,

Davis,

I tried uuu on RPi4 (64bit version) and it kinda works. However due to USB stack issues on RPi you won't be able to use it as a dispatcher for imx8m board. I tried this, spent 3 days trying to fix the issues and gave up. I ended up with a cheap NUC as a dispatcher. Mind you, I'm using 'flasher' deployment with a simple script as our CI produces multiple binaries to flash and requires a .uuu script to handle them properly.

Best Regards, MIlosz

Hi Milosz,

Your feedback on the raspberry pi was insightful. Thank you.

I'm intrigued about your comment regarding "flasher" deployment as we also use CI to build and store uuu packages to artifactory so it would be nice to provide lava with a simple script that:

a) pulls specific uuu package from artifactory b) runs: uuu <path to uuu package>

I can see that the lava does have a uuu deployment target however I am required to specify a path to the bootloader and system image separately:

• deploy: to: uuu images: boot: url: https://.../imx-boot-sd.bin-flash system: url: https://../imx-image-multimedia.rootfs.wic

I'm unable to find the flasher deployment action in the lava docs (https://docs.lavasoftware.org/lava/actions-deploy.html?highlight=deploy). Was this feature removed?

I don't think so, the code is there: https://git.lavasoftware.org/lava/lava/-/blob/master/lava_dispatcher/actions...

I guess just the docs are missing. What you need is to set "flasher_deploy_commands" in your device dictionary. It will call whatever commands you need on the dispatcher (it's a list). In this variable you can use the files from the deploy section. For example my imx8 flashing script call looks like this: 'flash-imx8.sh -i "{IMAGE}" -b "{BOOTLOADER}" -u "{UBOOT}" -s "{SITIMG}" -p "1:2"'

Variables in the curly brackets come from 'images' section of the deploy method. My deploy looks like this: - deploy: timeout: minutes: 10 to: flasher images: image: url: https://url.to/image-imx8mmevk.wic.gz compression: gz bootloader: url: https://url.to/imx-boot-imx8mmevk sitimg: url: https://url.to/sit-imx8mmevk.bin uboot: url: https://url.to/u-boot-imx8mmevk.itb

I store the pre-built mfgtools on the dispatcher (they don't change very often) so I can do the path substitution in the .uuu script. But you can also download your mfgtools package and pass it to the script. flash-imx8.sh is my custom script, doesn't come from LAVA.

One thing to remember here is that before running tests you need to download lava overlay with tests inside. LAVA will prepare it for you, but you need to deliver it to the device somehow. 'flasher' doesn't change the binaries/rootfs the way other deployments might.

- boot: .... method: minimal transfer_overlay: download_command: cd /home ; wget unpack_command: tar -C / -xzf

Best Regards, Milosz

Hi, Davis,

I received internal mail about "uuu can now burn emmc/sd by only use one wic image" just last month. With current lava integration method, the answer is NO, we need that separate " imx-boot-64.bin" to detect if board is in "serial download mode" or not, unless later we find efficiency way to extract that from wic.

For UUU raspberry version, I'm not sure, you'd better directly consult at https://github.com/NXPmicro/mfgtools
