Details:

I tried to get avrdude working with a FT2232D, Atmega M324P and used the
default FTDI pin configuration as described in "avrdude.conf".

I first started with an precompilated Windows-Binary
(http://download.savannah.gnu.org/releases/avrdude/avrdude-5.11-Patch7610-win32.zip).
This version looks like "it's just working". But all tries to save the
flash-content in a raw-binary file ends with an empty file. My hope, the
latest svn version will fix it.

Now i tried the last svn version 1139 from 12.03.2013 - first compiled with
windows (mingw), second time compiled with linux. Both version not working
anymore - i just got a Connection timeout and the flash contents was erased.

Started searching the last svn version 'running' with linux and next buggy svn
version ends with the result svn1068 working, svn1098 ist not working anymore.
To my regret, it's to much changed between this 2 version to find the bug as
outsider.

--> looks like it's working
