When dealing in such embedded systems, there's often not a whole lot of help online for arcane issues. Device documentation etc. usually makes default assumptions about C/C++. Drivers, other tools - same. This is usually a big concern. If there isn't much software involved, then the natural choice would be that which most easily integrates with the platform, because at that level, there's always trouble. Given limited information, I probably would have chosen C/C++, and then done some experiments with Rust to see if it was worthwhile, and then possibly port over during an appropriate iteration.
