srec_ascii_hex(5) File Formats Manual srec_ascii_hex(5)NAMEsrec_ascii_hex - Ascii-Hex file formatDESCRIPTIONThis format is also known as the Ascii-Space-Hex or Ascii-Hex-Space format. If you know who invented this format, please let me know. If you have a better or more complete description, I'd like to know that, too. The file starts with a start-of-text (STX or Control-B) character (0x02). Everything before the STX is ignored. Each data byte is represented as 2 hexadecimal characters, followed by an "execution character". The default execution character is a space, although many programs which write this format omit the space character immediately preceding end-of-line. The address for data bytes is set by using a sequence of $Annnn, characters, where nnnn is the 4-character ascii representation of the address. The comma is required. There is no need for an address record unless there are gaps. Implicitly, the file starts a address 0 if no address is set before the first data byte. The file ends with an end-of-text (ETX or Control-C) character (0x03). Everything following the ETX is ignored. It is also possible to specify a running 16-bit checksum using a sequence of $Snnnn, characters, although this usually appears after the ETX character and is thus often ignored. Variant Forms In addition to a space character, the execution character can also be percent (%) called "ascii-hex-percent" format, apostrophe (') or comma (,) called "ascii-hex-comma" format. The file must use the same execution character throughout. If the execution character is a comma, the address and checksum commands are terminated by a dot (.) rather than a comma (,). Size Multiplier In general, binary data will expand in sized by approximately 3.0 times when represented with this format.EXAMPLEHere is an example ascii-hex file. It contains the data "Hello, World[rq] to be loaded at address 0x1000. ^B $A1000, 48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 0A ^CCOPYRIGHTsrec_cat version 1.58 Copyright (C) 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 Peter Miller The srec_cat program comes with ABSOLUTELY NO WARRANTY; for details use the 'srec_cat -VERSion License' command.
