Re: How to obtain and save the return address inside an interrupt?

Another way to do this (examine the stack, check the value of SP and check ... ) in IAR -- you should do:
- menu: Project->Options->Debugger-> uncheck <Run to> box
- hit Download and Debug
- in the Disassembly window set a breakpoint on the green line (under __program_start symbol)
- hit Go and set the conditions for reset
- the debugger will stop the MSP at the very first instruction after reset and you can then examine whatever you consider to help you
Hope this helps
