News

20 Mar 2009 - V1.21 released.
31 Oct 2004 - V1.20 released.
18 Jun 2003 - Link to Peter Miller's SRecord changed to SourceForge.
9 Apr 2002 - V1.11 released and link added to Peter Miller's SRecord site.
28 Nov 2001 - s-record.com has been moved to a new ISP hosting service. It no longer re-directs.
7 Sep 2001 - Due to problems with the transfer to a new ISP the download link became invalid. This has now been fixed.

Unfortunately I haven't had enough time to make many serious alterations to this site.
I am still planning to add a section detailing the format of the S-Record file. This is currently under construction.

SREC2BIN and BIN2SREC

In 2000 I found myself in need of a DOS program (to run from a batch file) to convert a Motorola S-Record file into a binary image. I had a couple of programs which claimed to be able to do this however they both had a 64 KB binary file size limitation. This was presumably because of the memory segment arrangements imposed by DOS real mode. I therefore decided to write a program in my spare time to overcome this limitation. While I was at it I also wrote a program to convert the other way. A few of my colleagues liked my programs and suggested that I post them on my web site, which I did. I have received several e-mails from around the world as a result, with a few suggestions for new features, most of which have been included in the latest version.

The latest version (V1.21) compiles under Linux as well as the free GNU based MinGW tools. The programs are now small EXE files that have been tested on Windows 98SE, NT4, 2000, XP and Vista. You should be able to compile on any GCC platform.

Download srec_121_src.zip which contains source code, or srec_121_win.zip which contains the compiled Win32 EXEs.

Older versions are still available here.

Thanks to all the people who have contributed suggestions and ideas.

SREC2BIN features:

No 64 KB limit on file size.
The minimum size of the generated binary file can be specified.

BIN2SREC features:

No 64 KB limit on file size.
An offset for the generated addresses in the S-Record file can be specified.
Specify the number of bytes to use for the address in the S-Record.
Specify the line length of the S-Records in the file.
Headers and footers can be suppressed to allow multiple S-Record files to be concatenated.

New features for SREC2BIN V1.10:

Ignore S0 records with miscellaneous information which previously caused errors.
Ignore lines which don't contain data records - these also caused "not an S-Record" errors.
Add an option to change the default FF filler byte.
An address offset can be specified.

By default, an S-Record file with one data byte at address FFFFh will create a 64 KB binary file since the start address off the binary file will be 0. By specifying an offset of FFFFh a 1 byte binary file can be created; an offset of FFF0h would create a 16 byte binary file.

New features for BIN2SREC V1.10:

Allow the user to select part of the binary file - i.e. specify a start and end address.

New features for V1.11:

Tidied up and changed to use the Borland C++ V5.0 compiler so that the source code can be distributed.
The GNU General Public Licence has also been added.

New features for V1.20:

Now compiles using mingw32-gcc from the MinGW tools.

The Future

Other ideas which may be forthcoming in future versions:

Generate multiple S-Record files for 2 or 4 ROMs.
Drag and drop Windows versions - the command line versions would continue to be supported.

Useful Links

The MinGW GNU tools used for compiling the S-Record utilities were downloaded from http://www.mingw.org/.
Peter Miller has written an excellent utility called SRecord for Linux. This also has source code available and can be compiled for Windows systems using the Cygwin API. This utility has support for more file types than SREC2BIN and BIN2SREC but is obviously not as small or straghtforward to use. :-)
