Hello.  
When my application crashes, legato stores file **/tmp/legato\_logs**.  
**system log** file and **core dump** file.  
I get this file to my host machine. Ubuntu 18.04

How can I analyze a files to understand at what point the program occurred?

Is it possible to do this on my machine?

Hi @zuuuuk, can you check the last few messages of “logread” output to understand what did your app do before the crash?  
I don’t think you can decode the core dump.
