[sdiy] Odp: Re: ARM Dev Boards Possibly Lunatic Idea

[Roman]

This is exactly how I program all my PICs. My "programming pen" isn't so nice, it doesn't even look like a pen. Actually it's so ugly that I'm embarassed to show any picture. Done it probably 10 years ago with the intention to make proper one in spare time next week. Well, that never happened.   By the way that website is full of good stuff! Go and see it all if there's anybody except me who haven't seen it already. That guy, Mike Harrison, is a genius!

JTAG pins aren't connected.  From what I see (and I  could be "blind"), the  only way they could have done it is via FTDI or possibly using a socket that  accepts the SMD part,  program it first and then solder it, but that seems a bit labor intensive to  me.  The datasheet  lays out (I believe) 4 methods of programming the Flash, and the schematic  didn't seem to support  any except for FTDI.  Note though that the FTDI port was just .1" spaces  holes into which pins  could be soldered, but the board comes with nothing soldered there.  I  suppose it would be easy  enough to deal with that using some clip-thingies.   And that's why I'm asking this question here.

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?   -- ScottG  ______________________________  -- Scott Gravenhorst  --  scott.joviansynth.com scott.joviansynth.com  -- When the going gets tough, the tough use the command line.  -- Matt 21:22   ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org    ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org    -- ScottG  ______________________________  -- Scott Gravenhorst  --  scott.joviansynth.com scott.joviansynth.com  -- When the going gets tough, the tough use the command line.  -- Matt 21:22   ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org   ---  This email has been checked for viruses by AVG.  www.avg.com www.avg.com   ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org
