I have a client who needs to write program hex files to flash in installed AT91SAM2S256 chips. The board is fitted with the standard ARM 20-pin JTAG connector. I'm getting my head around OpenOCD and gdb, but they seem too complicated for a civilian. Would anyone like to share experiences with simpler software, possibly Windows-based? Recommendations for interface hardware, software packages, etc.? Thanks, Mel.

Is there a serial port connected to the outside world ? Is programming to be done within a sealed box, i.e. is the board access available ? Google for "AT91SAM7S256 boot loader", there are lots of ideas there. don

H-JTAG is free; the clone is cheap. http://hjtag.blogspot.com/ http://www.sparkfun.com/commerce/product_info.php?products_id=275 It wants a real parallel port, though. A step up is the Scarabeus debugger package and usbScarab from Kristech. It can also use the Wiggler. <http://www.kristech.eu/ang/index.php?option=com_content&task=view&id=37&Itemid=60> I generally use the NoICE debugger along with a Segger J-Link USB pod. Very quick and easy to connect/burn/trace/debug. A nice package but kinda pricey. Using the RDI capability of H-JTAG, NoICE will chat with the chips through the Wiggler (or clone) if you have a parallel port. http://www.noicedebugger.com/index.html http://www.segger.com/jlink.html -- Rich Webb Norfolk, VA

That is what I mean> A little more information would be helpful. > Is there a serial port connected to the outside world ? > Is programming to be done within a sealed box, i.e. is the board access > available ?Serial could be arranged. JTAG would be be OK if the process could come down to "Run these programs according to this simple checklist." Board access is possible too. Client is having the boards custom built. We have wiggler clones that appear to work well with the target processor on AT91SAM7S-EK. All concerned still have very little experience with this particular chip.> Google for "AT91SAM7S256 boot loader", there are lots of ideas there.Mel.

That's one of the packages included in WinARM, of course. I'll set it up and give it a run.

It's basically a scriptable ARM JTAG debugger. Several of our clients use them for production flashing. The nice part is that you can save the configuration on the widget itself - a bit more set up but ideal for production.
