NAME
srec_stewie - Stewie's binary file format
DESCRIPTION
If you have a URL for documentation of this format, please let me know. Any resemblance to the Motorola S-Record is superficial, and extends only to the data records. The header records and termination records are completely different. None of the other Motorola S-Records record type are available. The Records All records start with an ASCII capital S character, value 0x53, followed by a type specifier byte. All records consist of binary bytes. The Header Record Each file starts with a fixed four byte header record. +-----+------+------+------+ |0x53 | 0x30 | 0x30 | 0x33 | +-----+------+------+------+ The Data Records Each data record consists of 5 fields. These are the type field, length field, address field, data field, and the checksum. The lines always start with a capital S character. +-----+------+---------------+---------+------+----------+ |0x53 | Type | Record Length | Address | Data | Checksum | +-----+------+---------------+---------+------+----------+ Type The type field is a one byte field that specifies whether the record has a two-byte address field (0x31), a three-byte address field (0x32) or a four-byte address field (0x33). The address is big-endian. Record Length The record length field is a one byte field that specifies the number of bytes in the record following this byte. Address This is a 2-, 3- or 4-byte address that specifies where the data in the record is to be loaded into memory. Data The data field contains the executable code, memory-loadable data or descriptive information to be transferred. Checksum The checksum is a one byte field that represents the least significant byte of the one's complement of the sum of the values repre- sented by the bytes making up the record's length, address, and data fields. The Termination Record Each file ends with a fixed two byte termination record. +-----+------+ |0x53 | 0x38 | +-----+------+ Size Multiplier In general, binary data will expand in sized by approximately 1.2 times when represented with this format.
EXAMPLE
Here is an hex-dump example file. It contains the data "Hello, World[rq] to be loaded at address 0. 0000: 53 30 30 33 53 31 10 00 00 48 65 6C 6C 6F 2C 20 S003S1...Hello, 0010: 57 6F 72 6C 64 0A 9D 53 38 World..S8
