Import files of various formats, apply simple manipulations, and merge them to a single output file.

usage: hexfile_merger with following options/commands:

-h/-help                            print this help
-v/-verbose [level]                 set verbosity level 0..3 (default: 2)
-import [infile [addr]]             import from file to image. For binary file (*.bin) provide start address (in hex)
-export [outfile]                   export image to file
-print                              print image to console
-fill [addrStart addrStop val]      fill specified range with fixed value (addr & val in hex)
-clip [addrStart addrStop]          clip image to specified range (addr in hex)
-cut  [addrStart addrStop]          cut specified data range from image (addr in hex)
-copy [fromStart fromStop toStart]  copy data within image (addr in hex). Keep old data
-move [fromStart fromStop toStart]  move data within image (addr in hex). Unset old data

Supported import formats:

• Motorola S19 (*.s19), for a description see https://en.wikipedia.org/wiki/SREC_(file_format)
• Intel Hex (*.hex, *.ihx), for a description see https://en.wikipedia.org/wiki/Intel_HEX
• ASCII table (*.txt) consisting of lines with 'addr value' (dec or hex). Lines starting with '#' are ignored
• Binary (*.bin) with an additional starting address

Supported export formats:

• print to stdout (-print)
• Motorola S19 (*.s19)
• ASCII table (*.txt) with 'hexAddr hexValue'
• Binary (*.bin) without starting address

Files are imported and exported in the specified order, i.e. later imports may overwrite previous imports. Also outputs only contain the previous imports, i.e. intermediate exports only contain the merged content up to that point in time.

Notes:

• this tool is written in ANSI-C, it should be compatible with any platform supporting e.g. GCC
• file and image buffers sizes are 10MByte. For larger buffers increase LENFILEBUF and LENIMAGEBUF in hexfile.h

If you find any bugs or for feature requests, please drop me a note.

Have fun! Georg
