Hello, Cool - yes makes sense to me then ;-) Basically I think your previous message was correct... it's been a while since I implemented my solution, but it does only require some very basic functions like you mention.

The point is: if I am a novice electronic guy, and I *sometimes* want to do some JTag, it is usually quite boring to go and buy a cheap jtag adapter - mostly because the delivery time is quite long and usually the jtag stuff to be done makes sense only if it is done within little time (e.g. for a weekend project). In these situations slowness of the adapter is not desiderable, but definitely not frustrating as abandoning the project because of missing components. Instead, "flashing the hypotetical jtag-adapter-firmware onto that Stellaris board I bought for experimenting some time ago" could be a good idea - and save some lives, maybe :) BTW, I'm from Italy - Near Torino - 44.961976N, 8.230600E -- Simone Baratta ------------------------------------------------------------------------------ _______________________________________________ UrJTAG-development mailing list UrJTAG-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/urjtag-development
