We recently did (attempted? ) an upgrade of our Yocto embedded build system from Fido to Krogoth and, other than one rather massive issue, it all went well.
The massive issue is the fact that X11 is apparently not starting correctly. The embedded device boots okay since we can see in via a serial console as well as connecting via SSH.
We've narrowed the actual issue down to the Xorg executable, after following the process the the rc5.d Xserver satrtup scripts and xinit - basically, Xorg is dumping core with the following output:
X.Org X Server 1.18.0

You can see in the final dozen lines or so that it gets a SIGSEGV. I've searched for a solution online but the only close one I've discovered (https://community.nxp.com/thread/327339) is for a different error.
For what it's worth, the working Fido variant is much the same (though with different version numbers for components, primarily Xorg 1.16.3) but it carries on after the "test Initializing EXA" line:

I'd appreciate any pointers on how best to debug/resolve this issue since I cannot appear to get any more detailed information out of `Xorg` itself. Or, alternatively, if anyone has seen this same (or very similar) problem, how was it solved?
Cheers,
Al.

may be you can enable coredump and collect it for offline post mortem
setting ulimit -c unlimited e.g. when you run the suspected program will dump it

Khem,
I managed to get gdb up and running on the target system by adding 'tools-debug' to the 'IMAGE_FEATURES' in my top level recipe, executing 'ulimit -c unlimited' as you suggested, and running 'Xorg -core'.
I'll start looking into it more deeply but initial investigation seems to indicate something has smashed the stack. Loading up the core file for a backtrace gives me:
Core was generated by `Xorg -br -pn -nolisten tcp -core'.
Program terminated with signal SIGABRT, Aborted.
#0 0x76afda54 in raise () from /lib/libc.so.6
(gdb) bt
#0 0x76afda54 in raise () from /lib/libc.so.6
#1 0x76afedd0 in abort () from /lib/libc.so.6
#2 0x00183708 in OsAbort ()
#3 0x0007e6c0 in ddxGiveUp ()
#4 0x001887ac in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
Not _overly_ useful information since, by the time you're in ddxGiveUp, you're already well and truly into the abort process. Still, it's a good starting point, so I'm appreciative of your assistance.
If anyone else also wants to weigh in with their advice (or even at least relatively intelligent speculation), I'd be grateful.
Cheers,
Al.
