RTOS for ARM A57(NVIDIA Jetson TX2 / TX2i)

mea

Hi all,

I would like to use RTOS in my project in NVIDIA Jetson TX2 developer kit. But all of them are expensive. And i tried Real-Time Scheduling with NVIDIA Jetson TX2 by installing preempt RT patch. But the patch is not %100 hard real time. And i do not know any information about guaranteed response time for preempt RT. Is there anyone here to worked preemt RT linux with ARM A57 CPU?

Best regards.

    Hi,

    Check out some free RTOSes for A57, they exist. You will probably have to port them to your board/specific processor though.

    For other options check out:

    - OpenAMP - use it to start unused A57 cores from A57 cores running Linux (Linux started on < cores than the processor has); use bare metal for hard RT.

    - Jailhouse hypervisor is quite nice; again bare metal for hard RT.
