[ECOS] Programming flash?

[Lewin A.R.W. Edwards]

Hello Paul,

Load the flasher program into RAM, and run the upgrade out of RAM using 
polled serial I/O to avoid annoyance and complications with interrupt tables.

If you can't find a pin that is documented to have this behavior, then that 
connection point on the core is probably tied internally and not brought 
out to a pin.
