To prepare ROM files for ECU programming, it is often necessary to convert Intel HEX format files into raw binary (BIN) files. The hex2bin utility is the standard tool for this conversion.

Overview#

Intel HEX files contain ASCII-encoded data with address information, which must be stripped and converted into a raw binary image to be readable by most EPROM programmers and ECU tuning software.

Conversion Procedure#

1. Download the Utility: Obtain the hex2bin executable.
2. Prepare the File: Ensure your source file is in the standard Intel HEX format.
3. Execute Conversion: Run the utility via the command line to generate the .bin output file.

Tip

Always verify the checksum of the resulting binary file against your original HEX file data to ensure the conversion process was successful and no data corruption occurred.
