i am working automotive domain,so we want to desingn multi os board for our project.can we use mulitple os in ARM cortex processor like (linux,windos,android ) ?which one is better cortex version for multi os?
Sure, you can run multiple different OS. But the setup of them is difficult. Or you go for a Hypervisor and run each OS in a separate domain. See for example PikeOS.
If you want to run an RTOS + Linux, my company offers also a solution.
W/o hypervisor, the separation will become a night-mare.
