How do I trace back where program was before hitting breakpoint

[Mitch996]

Hello, with a little research, I now decided that this is the general but incomplete (which is why I'm asking the question) step :

Immediately look up SP register, if the SP register has the address of MSP in it, then proceed to look up MSP register, other wise go with PSP register.

And... that's pretty much it, I'm using Keil uV5, and upon entering "MSP" in the address input box of a memory n (where n = 1,2,3,4... etc) window, I get this, and I have no idea what they are: Capture.PNG

According to my research, one of them is the address where my program was right before hitting the breakpoint.

Problem is, I don't know which one. Can you please help me?

Mitch,

Most debuggers have a call stack view which will automatically unwind the stack frames for you and present this information graphically. Which IDE are you using?

Cheers, Darren

Hello Darren, per my capture.png, it should be easily fathomed that I am using keil uV5.
