srec_brecord - Freescale MC68EZ328 Dragonball bootstrap record format DESCRIPTION
This data format is understood by Freescale MC68EZ328 Dragonball series processors on their internal UART. Lines Each line contains hexadecimal data, each byte represented by two hexadecimal nybbles in upper case. Characters not in this set, but larger than 0x30 (e.g. lower case) will be ignored, less than 0x30 (e.g. CR or LF) are considered record terminators. Comments are prob- lematic; don't try this at home. Fields Each line contains a 4-byte address (big endian), a 1-byte length-and-mode, and then data bytes as dictated by the length. There is no checksum. A zero length record is an execution start address record, non-zero length records are data. +--+---+---+---+---+---+---+---+---+----+-----+---+ |1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | ... | n | +--+---+---+---+---+---+---+---+---+----+-----+---+ | Address | Length | Data | +------------------------------+--------+---------+ The length-and-mode byte is formatted as follows: +--+---+---+---+---+---+---+---+ |7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | +--+---+---+---+---+---+---+---+ |Mode | R | Length | +------+---+-------------------+ Mode These bits are ignored by SRecord in input (00 = bytes, 01 = half words, 10 is reserved, 11 = long words). These bits are always zero on output by SRecord. R This bit indicates a data read rather than a data write; SRecord does not accept input files with this bit set, and will not set it on output. Length The length of the records data bytes. It does not include the address or length bytes. The maximum payload of a record is 31 bytes of data. Size Multiplier In general, binary data will expand in sized by at least 2.35 times when represented with this format. EXAMPLE
Here is an example b-record format file. It contains the data "Hello, World" to be loaded at address 0. 000000000D48656C6C6F2C20576F726C640A SEE ALSO

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 COPYRIGHT
