Obviously a thread safe copy mechanism still needs to be added to run AP and FBW in 2 threads but that should(TM) be relatively simple.
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.
