Good day,

As the title suggests I am working with a custom Android installation and I have encountered the "No suitable address space mapping found".

I have not cross-compiled lime.ko and module.ko with exactly the same compiler that I used to build the rest of my installation but I have carried out the build pointing to the same kernel directories and lime.ko can successfully be used to get a memory dump. Can this be the reason for the inconsistency?

Here is what I did:

1. I have downloaded lime from svn:

URL: http://lime-forensics.googlecode.com/svn/trunk/src

2. I have downloaded volatility from svn:

URL: https://volatility.googlecode.com/svn/trunk

3. I have cross-compiled lime for a custom android installation and produced a kernel module and with it I have successfully retrieved a memory dump of size a little less than 2GB.

1951400096 Jun 25 14:50 mem.dump

4. I have also created a profile pointing to the same custom android installatin:

*** note that pmem is not visited and pmem.c is not compiled ***

cd volatility/tools/linux
edit Makefile and cross-compile module.c and produce module.ko
dwarfdump -di module.ko > module.dwarf

head module.dwarf
