[sdiy] ARM Dev Boards Possibly Lunatic Idea

[Scott Gravenhorst]

Here's a possibly lunatic idea I've been mulling for awhile.

I was thinking that the Tsunami Super WAV Trigger Board has essentially everything I'd
want on a dev board, including the Microchip (Atmel) ATSAMS70N20 ARM (and again, the
only reason I'm interested in that particular chip is that the speed is almost 40%
higher than the STmicro ones).  

What I first wondered is whether it would be possible to completely replace the program
in it.  There is a firmware update function, but I doubt if that _completely_ erases and
replaces the code.  If I'm not mistaken (from looking at the schemo and reading the
datasheet) I might be able to program the board through the FTDI port on the board. 
However, I'm not sure, so maybe someone here has advice.  Anyway, my whole idea was to
buy a second WAV trigger and blow out the WAV trigger program and replace it with my own
designs - and use it as a dev board.  It's a bit more expensive than the other
selections we've discussed, but failing finding a dev board for ATSAMS70N20, if that
could actually work, I wouldn't mind spending the money.  The development platform for
the Microchip/Atmel parts is Atmel Studio, which itself is free, but I don't know if as
you use it you find that it needs bits and pieces that cost money - can anyone say if
that is true or not?

So is this total lunacy?
