Subject: | [Ltib] How to get an application backtrace |
Date: | Mon, 14 Sep 2015 13:16:36 +0000 |
Hey I don’t know if anyone out there in LTIB land has successfully done this or not but With all of the approaches I have tried off the internet to get a stack backtrace of my crashed application code on an LPC3250 CPU and Kernel 2.6.34,
nothing has worked. I have tried also using ‘catchsegv’ but the output does not make any sense. My code has deliberate SEGV errors to induce the dump code to work but the output is nonsensical. I find it interesting that when running debug with the exact
same code (Debug build) the GDB utility does a fine job of showing the stack back trace just the way I would like to see it almost but I have no idea how it does that. Also a common problem with ARM is the back trace count only accounts for 1 entry which
is the return from error interrupt (useless duh). Any suggestions I will repay with kindness when I can answer one of your questions. Chris Westervelt Senior Product Development Engineer Advantor Systems. http://www.advantor.com Mobile: (407) 595-7023
