Determining source of "reset"

[Richard Phillips]

Hello all,

I have a simple C++ application flashed to my device to operate the UART - every time I send a char from an external source, the device appears to reset - specifically, the disassembly window leaps to 0xfffffffe. The call stack shows - I'm speculating that perhaps I need to be handling an interrupt that isn't currently handled?

How can I trace back to see which (if any) interrupt has fired (and maybe not been handled)?

Regards, Richard.

Hung, I've gone back to the UART example (my code was based on it actually), I've made a few trivial mods to get it working on my custom hardware (pin changes, remove the LED stuff), and it works! So, now I need to figure out what's different...
