Description :
This is a Utility Script used for converting or merging different NVM files. Output file extension will decide merging into bin/text file.
- Converting NVM to BIN format
- Converting BIN to NVM format
- Merges Multiple NVM files to Single NVM file (if tags are duplicated, further right file has precedence)
- Combines BT and FM NVM files and generates a Multi BIN file.
- In all the cases it takes multiple input files of same type to generate a single Output file.
- Converting Multi Bin file to Split nvm files as split_bt.nvm and split_fm.nvm from input.bin file.
Usage:
%prog [--BT/FM] <input file list> -o <outputfilename.nvm/bin>
BT single nvm->bin conversion
%prog --BT input1.nvm -o output.bin
BT single bin->nvm conversion
%prog input1.bin -o output.nvm
BT multiple nvm->bin conversion
%prog --BT intput0.nvm input1.nvm [...] [-o output.bin]
BT multiple bin->nvm conversion
%prog intput0.bin input1.bin [...] [-o output.nvm]
BT multiple nvm merge
%prog intput0.nvm input1.nvm [...] [-o output.nvm]
%prog --BT intput0.nvm input1.nvm [...] [-o output.nvm]
BT&&FM bin merge
%prog intput0.bin input1.bin [...] [-o output.bin]
BT&&FM nvm->bin conversion
%prog --BT intput0.nvm [...] --FM input0.nvm [...] [-o output.bin]
BT&&FM nvm merge
N/A
BT&&FM bin->nvm conversion
%prog -s input.bin
