Hello guys,
I have been working on a project to run EI linux object detection model on Jetson nano using balena. I have been following this link from EI and this from balena. I am able to run sample app like smokeparticles running on balena os. I could install edge-impulse-linux but can’t run it. It says failed to start device monitor. I followed the instruction under troubleshooting guide and gave access to entire root folder. But still no luck. Has anyone done this work before or provide me any guidance? My repo is here .

Hi @mithundotdas,
It seems Adam has pointed you to our Balena contact, please let us know how that goes!

Hello @mithundotdas,
Is this the same error that you encountered some time ago for your “Building an AI-Powered Bird Watcher with Balena and Edge Impulse” project? This sounds familiar but maybe it is a different issue…
What kind of camera are you using? USB or CSI?
@gy4nt you had any issue with the the Jetson’s camera on Balena in the past?
Regards,
Louis

@louis i still didn’t have time to test Jetson Nano + Edge Impulse!
@mithundotdas could you please share more details about your set up? what camera do you use? Maybe it’s a good idea to check here to get more information.
looking fwd to see this running 
@louis I checked my old emails and it was different error on Pi 4. Initially we got “Unsupported architecture …” and then “No camera found”. On Jetson, the error is different. I am using USB camera. Verbose does not reveal any further error message.

A02 with SD card. Not sure if I am answering your question
What happens if you remove the docker-compose, bring your Dockerfile up to the root directory, and re-push it @mithundotdas?
@dtischler I started with that Then moved to docker-compose to add privilege flag to true and host to network.
Aha - gotcha. I’m wondering if CAP_SYS_ADMIN and/or CAP_SYS_RAWIO might be needed when using a Compose. I’m not totally sure, so it would basically be just a “try it and see what happens” test, ha! 
Having some trouble pushing to balena right now. May be my network acting up. Will update when it’s done with above suggested change.
Hi @mithundotdas,
I just thought of something, can you do that and check if it works:
$> whoami
your-username
$> chown -R your-username:your-username ~/.config
I had the same error during a workshop using the Jetson Nano: https://github.com/edgeimpulse/workshop-advantech-jetson-nano
Let me know,
Regards,
Louis
@louis @dtischler I tried both but still same issue. Not sure what I am missing.

Worked around that by just updating to https://github.com/libvips/libvips/releases/tag/v8.12.2 instead.
Camera is definitely detected by the system, but, for some reason EI won’t locate it…
At the end of this giant log below, I just disable camera, and it launches (though this defeats the purpose obviously LOL)

Hello @dtischler,
Worked around that by just updating to
https://github.com/libvips/libvips/releases/tag/v8.12.2instead.
This is strange, where did you get the jetson.sh installation script? In our documentation, we changed in december the jetson.sh to use vipsv8.12.1. Maybe I forgot to change the link somewhere…
Unfortunately I don’t have a Jetson Nano with me today so I cannot try. I will try tomorrow on my Jetson Nano 2G and Balena to see if I can reproduce the issue.
Regards,
Louis

Thanks @louis! Looking closer at the versioning issue, that was my bad, I already had jetson.sh on my local machine, and just copied it straight in…Now looking closer at the version sitting at https://cdn.edgeimpulse.com/firmware/linux/jetson.sh I see it has indeed been updated to a newer version. So, that was my bad for going with what I already had, ha!
But yep, once you have your Nano setup, I am curious to see what results you get. 
This is interesting. Someone found similar issue on Raspberry Pi 4 . https://github.com/just4give/balena-edge-impulse-linux/issues/10
