Hello @jg_spitfire,
Short answer, absolutely, yes. It's possible. I discussed the different possibilities for the ZCU102 in here. I'll be speaking about this particularly in about a week in Adapt 2021. Check out the following robotics talks we're giving:
- Expanding Kria SOMs Beyond Vision AI (with ABB Robotics)
- Bringing Adaptive Computing To Robotics
- ROS 2 Acceleration
You can register for adapt in here.

Hi,
I have a KRIA KV260 EVK and I would like to install ROS2 in Linux, here are the requirements to install ROS2:
Tier 1 platforms:
Ubuntu 20.04 (Focal): amd64 and arm64 Mac macOS 10.14 (Mojave) Windows 10 (Visual Studio 2019)Tier 3 platforms:
Ubuntu 20.04 (Focal): arm32 Debian Buster (10): amd64, arm64 and arm32 OpenEmbedded Thud (2.6) / webOS OSE: arm32 and x86So I need Ubuntu 20.04 but this is the first time I am gonna use petalinux so I dont know whether I could install Ubuntu 20.04 using petalinux or is petalinux the Linux distribution itself?, or maybe I should install Ubuntu directly on the KRIA EVK?, I ask for petalinux because the UltraScale docs says that if you dont have experience with Linux you should use petalinux. the KRIA KV260 already has a prebuilt image (petalinux) to be burn in the sd card, but as I mentioned before, I dont know if I could install ROS2 there.thanks
That's right, those are the official platforms according to REP-2000. In this case, PetaLinux is not an official platform within the ROS 2 ecosystem just yet, but we're looking into it. That doesn't mean you can't build ROS 2 from source today for PetaLinux. You can from the ROS 2 recipes, the same you can do so in any other Linux-based distro.
I'd encourage to wait for the talks and re-engage after that.That said, if you need immediate action. Here're two avenues for you to consider:
Xilinx has been leading the ROS 2 Hardware Acceleration Working Group since the beginning of the year. Our goal is to simplify the use of adaptive SoCs (targeting KV260 as the reference hardware platform) for ROS users to build their computational graphs. Here're a few additional links to get you up to speed (through maybe you're already aware):
- Proposal for ROS 2 Hardware Acceleration Working Group (HAWG)
- Announcing the Hardware Acceleration WG, meeting #1
- Hardware Acceleration WG, meeting #2 (there's an upcoming meeting at the end of Sept.)
- REP-2008 RFC - ROS 2 Hardware Acceleration Architecture and Conventions
Have a look at the source code we've contributed so far. You can get started with ROS 2 using the architecture proposed in there as follows:

ros2 run vadd_publisher vadd_publisherAs for any other Yocto-based project, you can pick the ROS 2 yocto recipes from the meta-ros. The journey might be a bit bumpy, so I encourage you to check Avenue 1.
