It’s already rooted. Here’s the GitHub repo if you’re interested in rooting yours: “frederic/superbird-bulkcmd”
It looks like it might be difficult to write custom applications for it though based on this info in the GitHub readme:
“At this point we had full u-boot access, as well as persistent ADB (root) access, we initially wanted to try to bring-up Android Automotive on the device, but 500 MB of RAM made Android near-impossible to port.
We also tried to get other GUI applications cough maybe doom cough running, but this device utilizes a QT feature called EGLFS, which doesn't have a window management system like X11 or Wayland, so it is hard to get additional applications running on the device, but hey, maybe someone in the community can get it working using the access we're providing!”
