Relatively common in more powerful embedded systems. See for example https://www.openampproject.org/ https://www.openampproject.org/ which is a framework for running multiple cores of Linux, baremtal, or an RTOS together.
- p_l 1y agoOpenAMP focuses on RTOS running on "subordinate" coprocessors. This is more of a good old classic partitioning, which was rare outside of hardware with special support for it. Most RTOS + non-RTOS combinations use RTOS doubling as hypervisor, with RT tasks running at guaranteed timeframes and non-RTOS guest running in more relaxed form.
