How to generate a process map

Legato Application Framework
1

I have a complex application that will crash after some time as there’s an illegal address . I’m struggling to find out why, and to do that I need to know what code was being executed when the illegal address was encountered. I have seen a pdf that goes through the steps to find why a Legato application is crashing, however I don’t have a process map.

Please can someone tell me how to generate a process map, or where I can find it if it’s generated by default. I’m using WP76xx tools, so “mksys -t wp76xx abc.sdef”. I will then be able to refer to that and look in the object files to see where it was when the illegal address was used.

Thank you - I think that fills the hole in my knowledge! I’m more a deep embedded programmer coming from platforms where these kind of things are fixed. So good to know that Linux tells you this stuff if you know where to look. I should be able to track it down from there.
