I tried a few other things, see below.

Subject: [yocto] Can't enable reverse debugging
I'm on poky/dizzy and I'm getting a segementation fault in my application
that I think may be related to a buffer overflow. I'm using the Eclipse plug-in
(on Eclipse Kepler) to debug on the hardware with GDB. I'm trying to enable
reverse debugging but I have not had any success and I'm looking for some
My target processor is an SAM9G25 (ARM926EJ-S core). I have been able to
debug through Eclipse on the target hardware without issue. I tried enabling
Reverse Debugging by going to Window->Customize Perspective...-
Command Groups Availability and selecting "Reverse Debugging". Nowthere is a "Reverse Toggle" button on my toolbar, but it is always grayed out
whether I have a debug session running or not. I have also tried entering the
command "record" from the GDB console after my program breaks at main.
When I run the program, I get the error message "Process record: failed to
record execution log".
I tried first running my application, pausing the debugger and then sending the "record" command. When I continued debugging, I got the following GDB error:
....x86_64-nativesdk-pokysdk-linux/gdb-cross-canadian-arm/7.7.1-r0/gdb-7.7.1/gdb/utils.c:1073: internal-error: virtual memory exhausted.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
I did some looking around and I couldn't see any reasonable answer to why this would happen. I also just noticed that for the Debug Configurations under Eclipse, the debugger settings tab doesn't have "Enable Reverse Debugging at startup" option listed for the C/C++ Remote Application debugging type. Is this option just not available to me with my environment?
Is there something that I'm missing from my build steps or some Eclipse
plugin that I may be missing that is causing issues for reverse debugging? Or
is there some hardware requirement that my system may not meet?
