-  - 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.
+  * Run Nucleo examples from SRAM
-  - RTEMS interrupt latency and jitter at different CPU loads (measured using GPIO input/output). Compare performance of different boards.
+  - GPIO toggling on bare-metal. Compare performance of different boards, flash/RAM/ITCM, etc.
