Hi all, I want to build a minimal computer-vision based system using Jetson Nano and Buildroot. Is it possible ? Thanks in advance, Khang

I once used buildroot to build a root filesystem for a Tx2; it ought to work for Nano. The problem you may run into is integrating the binary-only parts of the system. Depending on our exact use-case you might not need the binary-only components and this might be a non-issue.

Hi D3, Thanks for your info. I wonder if you could share your experience on installing the Buildroot customized rootfs into Tx2, please ? Thanks in advance, Khang

Hi @khang.letruong , I know this is an old thread, but wanted to let you know that I have a Buildroot port for the Jetson Nano (4GB SD card model - p3450-0000) that will be submitted to the main Buildroot project soon. There’s still a lot of work left for system configuration and packaging of NVIDIA…

@gleva That’s great news. Would you mind sharing a link to the upstream patch and discussion once submitted?

Hi @gleva , It’s very nice of you to inform! I’m a fan of Buildroot! K.

Hi @gleva , Hope you have a better time than I do every time I have to get the latest release for Jetson devices on our buildroot Best Regards, Juan Pablo

Hi @juan.tettamanti , I had some trouble for the first release of the Nano 2GB firmware (32.4.4?), and I had some doubts about whether the URLs would still be accessible without login, but I noticed that with the release of 32.5 BSP URLs no longer require login. Is this the difficulty you’re referri…

Hi @gleva , The urls no longer requiring a login is certainly a step forward, I hope I get to see more things in that line in the future. I’ll try to mention a few things I’ve ran into, though you might see them in a different light than I do: When working on a buildroot project, one of my first…

Hi @juan.tettamanti , I think you raise some very valid issues and these are pain points I know others are experiencing too. I can’t speak for NVIDIA on this matter – my opinions are just my own and my Buildroot work has been done purely in my free time, but I’ll try to respond to your points as you…

Hi @gleva , Regarding image size, I did a fast check on my rootfs size with cuda and it was about 215MB, so your 150MB without any extra stuff seems correct. However, if you need something like the nvidia performance primitives or tensorrt, it’s a different story. If you happen to use the shared l…

Khang,

I didn’t dig very deeply. I built a root fs and booted it. Beyond that I didn’t really explore much further.

I posted my configuration on this thread: [url]Embedded Linux - Jetson AGX Xavier - NVIDIA Developer Forums
