Just starting to use the TMS470R1B1, which is a high-temp, high-rel processor with the ARM M3 core.
At the customer's insistence I'm using the IAR IDE, and interrupts are all f***ed up. Even the IAR demos don't work, and the register definitions in the ever-so-easy-to-find files don't match the documentation or, apparently, reality.
I'm trying to figure out how much of this is me, how much is IAR, how much is TI, and how much is ARM.
So if anyone has happened to use that particular set of tools with that processor (or if the symptoms sound right for _any_ IAR IDE with a Cortex M3), I'd like to hear how you solved the problems.
