Richard, are you using windoze ??

As far as JTAG interfaces on development boards, we need to develop
on our target product, a complicated piece.

Our other engineers also have problems from time to time with the software drivers.

Luckily we haven't broken any hardware lately. It's always drivers and on windoze XP or 7 of some sort.

We tend to use these entire parts... Most of the peripherals and a lot of memory and pretty much all out speed wise.
This may be one reason why I was evidently the first (and only ?) one in north America to find a silicon bug in the old ATmega 32 Atmel chip which almost put my last company out of business.

I tend to bring out the worst in products I guess.
