Patch attached

good day
Writing you here to ask for little help ( don't know how to contact with you in 
other way). Recently i try to adopt plf extractor for Parrots Bluetooth kit. 
Looks like they have similar structure with some minor changes. Only one 
problem that i have - is CRC.
I don't know with which range of data i should calculate for it. Below i added 
image with cut of file from original Firmware, also attached that binary file. 
Could you point me the range of bytes to obtain CRC ?

p/s/ sorry that using not suitable page for that query.

Thank you.

What steps will reproduce the problem?
1. plftool --replace=kernel.plf --section=3 -ofirmware_new.plf 
-ifirmware_old.plf
2. Check file header

What is the expected output? What do you see instead?
header.filesize should be == total size (bytes) of file

quick note - trying to install usb_flash i had to install sudo apt-get install 
libusb-dev

and not libusb-1.2.2.0 to get to compile - works....

OS: Ubuntu x64 12.04 kernel 3.2.2, gcc 4.4, make 3.2

1. svn checkout libpdf
2. cd libplf
3. make

this results in:

Attached is a trivial patch solving the issue.
