-Performance problems:
-
-It seems the problem is that the actual flash programming takes time.
-hal_delay_us() is invoked between each time the
-CPU is polled for whether flash programming has completed.

-Flat profile:
-
-Each sample counts as 0.01 seconds.
- % cumulative self self total
- time seconds seconds calls Ts/call Ts/call name
