Try an interesting project, the successor of MobLin — Tizen
(on the wiki
). In principle, as a replacement for an RTOS for a number of projects going.
In particular Intel on this platform makes the stack for auto-security (I know from personal conversation, I can't provide a link unfortunately). We looked at QNX for work in similar projects — unfortunately didn't fit — no support for CUDA, there is Tizen, respectively.
