The Motorola S-Record file format, also known as S19, S28, or S37 files, is a text-based format for conveying binary data. It's primarily used to transfer firmware or program code to embedded systems, microcontrollers, and programmable logic devices. Each line in an S-Record file represents a record containing a hexadecimal representation of data, along with address information, a record type identifier, and a checksum for error detection. The format is designed for reliable data transfer, ensuring that the data is correctly received and interpreted by the target device. S-Records are commonly used in programming tools, debuggers, and loaders for embedded systems development. The format's simplicity and human-readability make it suitable for both automated and manual data transfer processes. The checksum helps to verify the integrity of the data during transmission, reducing the risk of corrupted code being loaded onto the target device. Different record types within the S-Record format define the address size and the type of data being transferred, allowing for flexibility in handling various memory configurations and data structures.
