We are working on an SLAM tracking system, surface segment and reconstruction, and streaming the down sample mesh into Unity, we had Unity run on NUC with Linux, but have trouble have Unity engine directly run on Jetson TX2, wondering if anyone ever did it or if it’s possible to do it? Thanks for help! (We are working on an augmented reality glass and platform)
When you say “have trouble running Unity directly on Jetson,” what do you mean?
Does Unity have a Linux engine download for arm64 archiecture?
If so, do you get any particular errors when trying to run it?
The Jetson TX2 is an ARM architecture, and no install is available, I tried with sh file and the same, when trying ./Unity I got : bash: ./Unity: cannot execute binary file: Exec format error
Unity cilents do support ARM architecture:
https://community.arm.com/graphics/b/blog/posts/arm-guide-for-unity-developers-v3-3
It also runs on iOS and Android devices which are all ARM.
To know what the specific format/architecture of whatever file you want to run, try:
file the-filename
So, for example:
file Unity
If it’s a file intended to run on ARM, it should say so. For example:
ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.26
Note that, to run 32-bit executables on 64-bit ARM, you have to enable mutiarch using dpkg, and then install the necessary “armhf” version libraries. (This is common for other software like Arduino as well.)
Here’s a good set of libraries to get started (I use this for other software, not for Unity, so I don’t know if this is sufficient):
sudo dpkg --add-architecture armhf

However, if you want to run the Unity editor (not just a built client) on ARM, no, I don’t think they support that.
I know that Unreal Engine editor can be built from source on Linux, so you may be able to switch to Unreal, if you need to run the editor on the TX2. 8 GB may not be enough RAM, though.
I can see reference: https://forum.unity.com/threads/experimental-android-64-bit-arm-support-a-k-a-arm64-a-k-a-aarch64.512010/ , but I haven’t heard of folks used unity at jetson. If I needed to I would run unity at Host PC and delivered the Unity application over the network to the Jetson.
Hey Andrey,
the above thread refers to Android and while it’s is sorta Linux I’m very skeptical that the binary will run on Tegra Ubuntu with Nvidia graphics.
Anything to the contrary?
Thanks
G.
I realized that I can use VisionWorks for that niche.
Thanks
G.
Any update on either compiling the unity engine on ARM (specifically on TX1/TX2) or exporting a binary from unity running on a non-ARM host machine (x86)?
