Do you have experience with FreeBSD on ARM processors?
The simple solution, which may not be possible, is to
make all software on the flash disk RO, and put any part
of the file system that needs to be written onto a RAM
disk... probably should be the /var directory.
The only time the flash disk must be written is when some
configuration parameter must be changed, or the linux/program
image must be changed.
The routines that make those changes could be fashioned
so that they flush the caches immediately after they are finished.
From observation, the BBB keeps operating for several seconds
after power is removed. If a power failure interrupt is
created that will notify linux instantly on power failure, it
would be possible to forbid configuration changes that take
longer than a couple of seconds.
