NAME
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
Here is an example Tektronix hex file. It contains the data "Hello, World[rq] to be loaded at address 0. /00000D0D48656C6C6F2C20576F726C640A52 /00000000
