Having AP and FBW in 2 threads is a good start for increasing security, 
but using the MPU (memory protection unit) to guarantee
that AP or any other thread (payload managing thread) cannot  trash the 
private memory of FBW would be even better.

Unfortunately, MPU of armv7-e (F4 and F7) is not so easy to use, and not 
yet abstracted by ChibiOS.
