srec_tektronix_extended - Tektronix Extended hexadecimal file format DESCRIPTION
This format allows binary files to be uploaded and downloaded between two computer systems, typically between a computer system (such as a PC, Macintosh, or workstation) and an emulator or evaluation board for microcontrollers and microprocessors. The Lines Lines always start with a percent (%) character. Each line consists of 5 fields. These are the length field, the type field, the check- sum, the address field (including address length), and the data field. The Fields +--+--------+------+----------+---------+------+ |% | Length | Type | Checksum | Address | Data | +--+--------+------+----------+---------+------+ Record Length The record length field is a 2 character (1 byte) field that specifies the number of characters (not bytes) in the record, exclud- ing the percent, the length field, the type field and the checksum. Type The type field is a 1 character field that specifies whether the record is data (6) or termination (8). Checksum The checksum is an 2 character (1 byte) field that represents the sum of all the nibbles on the line, excluding the checksum. Address This is a 9 character field. The first character is the address size; it is always 8. The remaining 8 chgaracters are the 4-byte address that specifies where the data is to be loaded into memory. Data The data field contains the executable code, memory-loadable data or descriptive information to be transferred. Record Types 6 A record containing data. The data is placed at the address specified. 8 A termination record. The address field may optionally contain the address of the instruction to which control is passed. There is no data field. Size Multiplier In general, binary data will expand in sized by approximately 2.5 times when represented with this format. EXAMPLE
Here is an example Tektronix extended file. It contains the data "Hello, World[rq] to be loaded at address 0x006B. %256D980000006B48656C6C6F2C20576F726C64210A %09819800000000 COPYRIGHT

srec_tektronix - Tektronix hexadecimal file format DESCRIPTION
The Tektronix hexadecimal file format is no longer very common. It serves a similar purpose to the Motorola and Intel formats, usually used to transfer data into EPROM programmers. The Lines Most Tektronix hex files contain only Tektronix hex lines (see the next section), which always start with a slash ("/[rq]) character. There are only two types of lines - data lines and a termination line. Data Lines Data lines have five fields: address, length, checksum 1, data and checksum 2. The lines always start with a slash ("/[rq]) character. +--+---------+--------+-----------+------+-----------+ |/ | Address | Length | Checksum1 | Data | Checksum2 | +--+---------+--------+-----------+------+-----------+ Address This is a 4 character (2 byte) address that specifies where the data in the record is to be loaded into memory. Data Length The data length field is a 2 character (1 byte) field that specifies the number of character pairs (bytes) in the data field. This field never has a value of zero. Checksum 1 The checksum 1 field is a 2 character (1 byte) field. Its value is the 8-bit sum of the six 4-bit values which make up the address and length fields. Data The data field contains character pairs (bytes); the number of character pairs (bytes) is indicated by the length field. Checksum 2 The checksum 2 field is a 2 character (1 byte) field. Its value is the least significant byte of the sum of the all the 4-bit val- ues of the data field. Termination Line Termination lines have three fields: address, zero and checksum. The lines always start with a slash ("/[rq]) character. +--+---------+------+----------+ |/ | Address | Zero | Checksum | +--+---------+------+----------+ Address This is a 4 character (2 byte) address that specifies where to begin execution. Zero The data length field is a 2 character (1 byte) field of value zero. Checksum The checksum 1 field is a 2 character (1 byte) field. Its value is the 8-bit sum of the six 4-bit values which make up the address and zero fields. Size Multiplier In general, binary data will expand in sized by approximately 2.4 times when represented with this format. EXAMPLE
