Before you can use the MLC extractor tool (MET), you need to customize it for your hardware and rebuild it.
You will need the CodeSourcery GNU toolchain (EABI version) to build the files. Download the CodeSourcery toolchain from here. A free 'lite' version is available that can be used to build the MET. Install the tools and make sure the PATH environment variable for the tools is setup correctly.
MET relies on the Common Driver Library (CDL) for some of it's functions, so the LPC32x0 CDL (v2.11 and later) must be downloaded and installed first. You can download the CDL from here. Once the CDL is downloaded, install it by extracting the directory somewhere on your Windows XP/Vista/7 machine.
Download the MET file from this page and extract the contents into the CDL directory from the step above. The file must specifically be extracted in the ./csps/lpc32x0/bsps/common/examples directory.
The most likely change needed to the source code is adding a specific NAND device to the NAND detection list. In the mlc_fgen_tool folder in the ./csps/lpc32x0/bsps/common/examples directory, edit the nandif.c file and locate the sys_nand_ids structure. This structure contains a list of recognized NAND IDs with geometry for each ID. This list is self-explanatory - either edit an existing entry in the list or add a new entry in the list with the new NAND information.
<code>
/* ST MICRO Flash */
{
LPCNAND_VENDOR_STMICRO,
0x73, /* Device ID */
512, /* Page size */
32, /* Pages per block */
1024, /* Total blocks */
{SLCNAND_DEFAULT_TIMING, MLCNAND_DEFAULT_TIMING},/* Timing */
}

You can rebuild the code with the steps below.
First, open a Windows 'cmd' shell and switch to the CDL directory. Use the "setenv" command to setup the environment for build. Note the 2nd parameter (board) doesn't matter, so we'll use "ohy3250". The 3rd parameter is the toolchain which will be ""gnu". The 4rth parameter is "1", indicating verbose output.
Switch to the mlc_fgen_tool directory and type "make". If the tools are installed and everything is setup correctly, the tool will build and you will get a "mlcextractor.bin" file that can be used with the serial loader tool.
