EL2 Monitor NXP RTOS Integration

About This Training

This guide demonstrates how EL2 Monitor integrates with the NXP real‑time OS running on two cores under a common hypervisor environment. It outlines the required modifications to remove EL2‑level instructions, build multi‑instance RTOS binaries, and load them alongside the EL2 Monitor binary using NXP debugging scripts. The integration showcases how EL2 Monitor traps and analyzes GIC distributor accesses, allowing the OS to execute safely without triggering aborts.

What You Will Learn

• Runs multi‑instance NXP RTOS samples across two cores managed by a single EL2 Monitor.
• Requires removal of EL2‑level instructions from RTOS startup code to avoid aborts.
• Sample RTOS configuration provided for EB Tresos to simplify setup.
• EL2 Monitor loaded via NXP’s CMM scripting, with program counter starting at EL2_Reset_handler.
• Demonstrates GIC distributor access trapping and safe continuation of OS execution.
