+  - GPIO toggling on bare-metal. Compare performance of different boards, flash/RAM/ITCM, etc.
+  - Interrupt latency (GPIO input/output) on bare-metal. Compare performance of different boards, flash/RAM/ITCM, etc.
+  - GPIO toggling on RTEMS using a single uninterrupted task. Compare performance of different boards. Useful to make sure the systems and toolchains are working as expected. Running from flash/RAM/ITCM.
+  - RTEMS interrupt latency and jitter at different CPU loads (GPIO input/output). Compare performance of different boards.
+  - RTEMS scheduling latency and jitter using mutex at different CPU loads (measured using two GPIO outputs). Compare performance of different boards.
+  - RTEMS periodic timer jitter at different CPU loads (measured using one GPIO output). Compare performance of different boards.
+  - RTEMS contribution: CPU load
+  - RTEMS contribution: task priority assignment with ML
