| * GPIO togling. No RTOS functionality involved. How does it compare to e.g. bare-metal with libopencm3? | * Run Nucleo examples from SRAM |
| * Ping-pong between 2 tasks using mutex (different loads). Context switching. Mutex operations. | - GPIO toggling on bare-metal. Compare performance of different boards, flash/RAM/ITCM, etc. |
