Postmortem debugging with arm-none-eabi-gdb from memory dump (not core)

[Hesham M <hesham.eembedded@gmail.com>]

Hi all,

As this is my first email to the list, and as an old user for gdb, I'd like
first to thank the gdb community for their effort.

In a bare-metal ARM system, is there a way to use arm-none-eabi-gdb for
postmortem debugging, the same way we do when we debug with core file on
Linux, for example?

The issue is that I don't have a "core" file but I can generate memory dump
of the whole memory (ROM is already known and through the hardware debugger
used I can write the RAM contents to a file (outside the target of course).
I can also collect the registers at the time of the crash. I can do the
debugging/analysis if I connect gdb to the target at the time of the crash
but I need to do this in later time away from the target. I hope to find a
way to debug with memory dumps the same way gdb debugs with core files.

Of course if I can convert the memory dump to a valid core file, it might
be another path to the solution. I don't know how to do that or if there is
a tool that can help with this conversion.

Any idea if this is possible?

A variant of this is idea is done for Keil tools:

I have posted a similar question on stackoverflow but they closed it! So,
please let me know if my question isn't clear.

Thanks,
