Provides dedicated tools for IMX NAND dumps reverse-engineering:

• imx-nand-info: parse the FCB and display useful information about the Flash structure
• imx-nand-convert: parse the FCB and convert the actual dump into a memory-based image that can be processed with binwalk

You can choose to either install imx-nand-tools from PyPi or from the source.

That's the most easiest way to install imx-nand-tools:

$ sudo pip3 install imx-nand-tools

It will install imx-nand-tools and all its dependencies.

The following commands will install imx-nand-tools from source.

$ git clone https://github.com/DigitalSecurity/imx-nand-tools.git
$ sudo pip install setuptools
$ cd imx-nand-tools
$ python setup.py build
$ sudo python setup.py install

And that's it

This tool loooks for the first Firmware Control Block (FCB) contained in a dump and parse it and then displays its contents.

$ imx-nand-info fresh-dump.bin

This tool converts a fresh i.MX NAND dump into a useable memory image:

$ imx-nand-convert fresh-dump.bin converted-dump.bin

The -c option enables error correction thanks to embedded ECC information, thus imx-nand-convert will be able to fix potential errors in the original NAND dump.
