Small Utility for unpacking UAFFS1 image files. (i rewrite on Delphi)

1. In brief


Unpacking UAFFS1 is not big mystery but also exist troubles in this operation.

Exist big NAND flash files with different geometry:

Alcatel uses standart maybe geometry: 2048 bytes sector size with 64 bytes spare

size but one Lenovo A60+ uses 4096 bytes sector with 128 bytes spare size.

This application can upack img file with customied sector and spare size.


2. Config


-----------------------------
[General]

CHUNK_SIZE = 2048
SPARE_SIZE = 64
-----------------------------

Values can be edited with favorite text editor.


3. Usage

Code:
C:\yaffs\Delphi\Win32\Debug>UnYaffs.exe secro_lenovo.img
UnYaffs Version 1.0
  Copy Left(R) 2013 Victor Levunliev.
Based on Kai Wei source. http://code.google.com/p/unyaffs/
