Can the Nitrogen95 run a real-time OS alongside Linux?

Answer

 Yes. The i.MX 95's asymmetric multiprocessing (AMP) architecture dedicates the Cortex-M7 core entirely to real-time workloads while the Cortex-A55 cluster runs Linux. This means you can run deterministic control loops (motion control, sensor acquisition, protocol stacks) on the M7 simultaneously with a full Linux stack on the A55 — without inter-board latency or a separate MCU on your carrier board. The Cortex-M33 adds a third domain for safety/low-power functions such as watchdog management and secure key storage, further reducing the need for external companion chips.
