Hi,
I am using GDB on an embedded system. My box is crashing, but i dont have the core file. All i
have with me is that backtrace and the information of the various registers when it crashed. Can i
with the help of below do some debugging. Can i use the PC to locate the exact line where my
device crashed. I have with the given back trace, noted the functions that the code was going thru
when the device crashed. Can i use these registers/PC for more info?
Screen Shots below.
