I have been looking around for multiple RTOS for the rpi3 but unfurtunately many of them are not (yet?) supported?

Could anybody tell me which ones can be used on the rpi3 now?

  • I'm not sure if the MachineKit project is of any use, http://www.machinekit.io/docs/getting-started/installing-packages/ they have a real-time kernel that can be used on the Pi, although possibly only the Pi2 is supported. – tobyd Feb 16 '17 at 12:56
  • What features of the RTOS are you going to use? Presumably not all RTOS will have implemented the features which are important to your application. – joan Feb 16 '17 at 13:35
  • @joan Idk yet. This will be the first time I will use an RTOS. So so far I am open to any RTOS that works on rpi3 model b. – LandonZeKepitelOfGreytBritn Feb 16 '17 at 17:22
  • I'd recommend against asking your question cross communities so quickly. Electronics migrated your other question here, which I've deleted. – Jacobm001 Feb 16 '17 at 19:11

I have not used it, and I think it does not qualify as a true RTOS, but if you want a platform on which a process can run uninterrupted for an arbitrary length of time, I believe RISC OS can deliver that (beware "RISC" also refers to an abstract sort of ISA on which ARM processors are based).

As per the wikipedia page, RISC OS uses cooperative multi-tasking:

...a style of computer multitasking in which the operating system never initiates a context switch from a running process to another process. Instead, processes voluntarily yield control periodically or when idle

By implication you can voluntarily not yield control. I don't know how feasible this is if you intend to have a long running process never preempt itself, but perhaps you actually do not need to go that far.
