Post mortem analysis in MQX

strlen — Fri, 16 Jan 2015 23:26:05 GMT

Hi all,

Apologies if this thread already exists somewhere. I'm working on a project and I'm in the process of tightening the screws a bit. I've been looking at the routines in kernel/klog.c, and a few routines to get information related to stack usage. Is there a way to get an actual stack trace? Minimally, I'm interested in being able to get a stack trace (with args) of a failed task at the time of failure and dump it out to persistent storage for later retrieval. Any advice would be *greatly* appreciated.

Thanks in advance,

Rob

Unfortunately, I don't think that's going to do it. I'm looking for a way of programatically determining the stack trace without having to use a debugger.
