PR20_02_RTEMS Develop a simple application on an ARM platform (SPI sensor throughput, CPU load, GPIO interrupt latency, interrupt latency with user thread processing, PPS jitter).

• MCU execution time
• TODO: Run RTEMS examples in Nucleo hardware
• TODO: Run RTEMS tests in Nucleo hardware

1. GPIO toggling on bare-metal as well as RTEMS using a single uninterrupted task. Compare performance of different boards. Useful to make sure the systems and toolchains are working as expected.
2. RTEMS interrupt latency using GPIO input/output at different CPU loads. Compare performance of different boards.
3. RTEMS scheduling latency using mutex at different CPU loads. Compare performance of different boards.
