+Yet Another Hex to bin converter
+
+It can handle the extended Intel hex format in segmented and linear address
+modes. Records need not be sorted and there can be gaps between records.
+
+Some hex files are produced by compilers. They generate objects files for each
+module in a project, and when the linker generates the final hex file, the
+object files are stored within the hex files, but modules can appear not
+necessary in order of address.
+
+How does it work?
+
+Hex2bin/mot2bin allocates a 4 MBytes buffer and just place the converted bytes
+in its buffer. At the end, the buffer is written to disk. Using a buffer elimi-
+nates the need to sort records.  If the option l is used (3), the buffer will be
+allocated with the maximum size specified if over 4Mbytes.
+
+Before reading the hex file, the buffer is filled with a default value. These
+padding bytes are all FF by default so an EPROM programmer can skip these bytes
+when programming. The padding value can be changed with the -p option.
+
+1. Compiling on Linux or other unix platforms
+
+	make
+
+	then
+
+	make install
+
+	This will install the program to /usr/local/bin.
+
+1a. Compiling for Windows on Msys, Cygwin or DOS prompt
+
+	The programs can be compiled as follows:
+	  gcc -O2 -Wall -o hex2bin.exe hex2bin.c common.c libcrc.c binary.c
+	  gcc -O2 -Wall -o mot2bin.exe mot2bin.c common.c libcrc.c binary.c
+
+2. Using hex2bin
+
+	hex2bin example.hex
+
+	hex2bin will generate a binary file example.bin starting at the
+	lowest address in the hex file.
+
+3. Binary file starting address and length
+
+	If the lowest address isn't 0000,
+	    ex: 0100: (the first record begins with :nn010000xxx )
+
+	there will be problems when using the binary file to program a EPROM
+	since the first byte supposed to be at 0100 is stored in the binary file
+	at 0000.
+
+	you can specify a starting address for the binary file on the command line:
+
+	hex2bin -s 0000 start_at_0100.hex
+
+		This start address is not the same thing as the start address record in
+		the hex file. The start address record is used to specify the starting
+		address for execution of the binary code.
+
+	The bytes will be stored in the binary file with a padding from 0000
+	to the lowest address minus 1 (00FF in this case).
+
+	Similarly, the binary file can be padded up to Length -1 with FF or another byte.
+
+	Here, the space between the last byte and 07FF will be filled with FF.
+	hex2bin -l 0800 ends_before_07FF.hex
+
+	EPROM, EEPROM and Flash memories contain all FF when erased.
+
+	This program does minimal error checking since many hex files are
+	generated by known good assemblers.
+
+	When the source file name is
+		for-example.test.hex
+	the binary created will have the name
+		for-example.bin
+	the ".test" part will be dropped.
+
+	Hex2bin/mot2bin assume the source file doesn't contain overlapping records,
+	if so, overlaps will be reported.
+
+4. Checksum of source file
+
+	By default, it ignores record checksum errors, so that someone can change
+	by hand some bytes allowing quick and dirty changes.
+	If you want checksum error reporting, specify the option -c.
+
+	hex2bin -c example.hex
+
+	If there is a record checksum error somewhere, the program will continue the
+	conversion anyway.
+
+	The example file example.hex contains some records with checksum errors.
+
+5. Check value inserted inside binary file
+
+	A check value can be inserted in the resulting binary file.
+
+	hex2bin -k [0-4] -r [start] [end] -f [address] -C [Poly] [Init] [RefIn] [RefOut] [XorOut]
+
+	-k  Select the check method:
+		   0:  Checksum  8-bit
+		   1:  Checksum 16-bit
+		   2:  CRC8
+		   3:  CRC16
+		   4:  CRC32
+
+    -r	Range to compute checksum over (default is min and max addresses)
+
+    -f  Address of the result to write
+
+    -C  Parameters for CRC
+        Parameters for common CRCs are listed in doc/CRC list.txt. They appear in
+        the same order. Feed them as is and use t for TRUE, f for FALSE.
+
+        See also the test/Makefile for these common CRCs; since they're tested,
+        you'll have the command line figured out.
+
+    -E  Endian for storing the check result or forcing it
+           0: little
+           1: big
+
+    Change from previous versions of hex2bin/mot2bin:
+	Replace former options to this version
+		  -k 1		->		-k 1 -E 0
+		  -k 2		->		-k 1 -E 1
+
+6. Value inserted directly inside binary file
+    Instead of calculating a value, it can be inserted directly into the file at a specified address.
+
+    hex2bin -k [0|1|2] -F [address] [value]
+
+	-k  Select the value format:
+
+		0 = 8-bit
+		1 = 16-bit
+		2 = 32-bit
+
+    -F	Address and value of checksum to force
+
+    -E  Endian for storing the check result or forcing it
+           0: little
+           1: big
+
+7. Motorola S files
+
+	mot2bin example.s19
+
+	Options for mot2bin are the same as hex2bin. Executing the program
+	without argument will display available options. Some are specific to
+	Motorola files.
+
+	This program will handle S19 files generated for Motorola micropro-
+	cessors. Since I use this program for an EPROM programmer, I will
+	rarely need to have more than 4M, I limited the source program for
+	24 bits or 16 bits address records.
+
+	32 bits records are now supported, but obviously I can't allocate all
+	the memory for the binary target. What I did is simply assume that the
+	binary file will occupy less than 4M. For binary files greater than 4M,
+	see length option (section 3).
+
+8. Support for byte-swapped hex/S19 files
+
+    -w	Wordwise swap: for each pair of bytes, exchange the low and high part.
+	If a checksum needs to be generated to insert in the binary file, select
+	one of the 16-bit checksums.
+
+	hex2bin -w test-byte-swap.hex
+
+9. Goodies
+
+	Description of the file formats is included.
+	Added examples files for extended addressing.
+
+	Check for overlapping records. The check is rather basic: supposing
+	that the buffer is filled with pad bytes, when a record overlaps a
+	previous one, value in the buffer will be different from the pad bytes.
+	This will not detect the case when the previous value equals the pad byte,
+	but it's more likely that more than one byte will be overlapped.
+
+
+10. Error messages
+
+    "Can't allocate memory."
+
+    Can't do anything in this case, so the program simply exits.
+
+    "Error occurred while reading from file"
+
+    Problem with fgets.
+
+	"Input/Output file %s cannot be opened. Enter new filename: "
+
+	The user may not have permissions to open the file.
+
+	"0 byte length data record ignored"
+
+	This means that an empty data record was read. Since it's empty, it's simply
+	ignored and should have no impact on the binary file.
+
+	"Data record skipped at ..."
+
+	This means that the records are falling outside the memory buffer.
+
+	"Overlapped record detected"
+
+	A record is overwritten by a subsequent record. If you're using SDCC, check
+	if more than one area is specified with a starting address. Checking the map
+	file generated by the linker can help.
+
+	"Some error occurred when parsing options."

+S-Record Format

+    

+    A file in Motorola S-record format is an ASCII file. There are three different 

+    formats:

+

+        S19     for 16-bit address 

+        S2      for 24-bit address

+        S3      for 32-bit address

+

+    

+    The files consist of optional symbol table information, data specifications 

+    for loading memory, and a terminator record.

+

+        [ $$ {module_record}

+        symbol records

+        $$ [ module_record ]

+        symbol_records

+        $$]

+        header_record

+        data_records

+        record_count_record

+        terminator_record

+

+

+Module Record (Optional)

+

+    Each object file contains one record for each module that is a component of it. This

+    record contains the name of the module. There is one module record for each relocatable 

+    object created by the assembler. The name of the relocatable object module

+    contained in the record comes from the IDNT directive. For absolute objects created

+    by the linker, there is one module record for each relocatable object file linked,

+    plus an additional record whose name comes from the NAME command for the

+    linker.

+

+    Example:

+

+        $$ MODNAME

+

+

+Symbol Record (Optional)

+

+    As many symbol records as needed can be contained in the object module. Up to 4

+    symbols per line can be used, but it is not mandatory that each line contain 4 

+    symbols. A module can contain only symbol records.

+

+    Example:

+

+        APPLE $00000 LABEL1 $ODOC3

+        MEM $OFFFF ZEEK $01947

+

+    The module name associated with the symbols can be specified in the

+    module_record preceding the symbol records.

+

+    Example:

+

+        $$MAIN

+

+    Symbols are assumed to be in the module named in the preceding module_record

+    until another module is specified with another module_record. Symbols defined by

+    the linker's PUBLIC command appear following the first module record, which

+    indicates the name of the output object module specified by the linker's NAME

+    command.

+

+

+*****************************************************************************************

+

+Header Record (SO)

+

+    Each object module has exactly one header record with the following format:

+

+        S00600004844521B

+

+    Description:

+

+        S0         Identifies the record as a header record

+        06         The number of bytes following this one

+        0000       The address field, which is ignored

+        484452     The string HDR in ASCII

+Intel
+Hexadecimal Object File
+Format Specification
+Revision A, 1/6/88
+
+
+
+DISCLAIMER
+
+Intel makes no representation or warranties with respect to the contents
+hereof and specifically disclaims any implied warranties of
+merchantability or fitness for any particular purpose.  Further, Intel
+reserves the right to revise this publication from time to time in the
+content hereof without obligation of Intel to notify any person of such
+revision or changes.  The publication of this specification should not
+be construed as a commitment on Intel's part to implement any product.
+
+
+1. Introduction
+This document describes the hexadecimal object file format for the Intel
+8- bit, 16-bit, and 32-bit microprocessors.  The hexadecimal format is
+suitable as input to PROM programmers or hardware emulators.
+Hexadecimal object file format is a way of representing an absolute
+binary object file in ASCII.  Because the file is in ASCII instead of
+binary, it is possible to store the file is non-binary medium such as
+paper-tape, punch cards, etc.; and the file can also be displayed on CRT
+terminals, line printers, etc..  The 8-bit hexadecimal object file
+format allows for the placement of code and data within the 16-bit
+linear address space of the Intel 8-bit processors.  The 16-bit
+hexadecimal format allows for the 20-bit segmented address space of the
+Intel 16-bit processors.  And the 32-bit format allows for the 32-bit
+linear address space of the Intel 32-bit processors.
+The hexadecimal representation of binary is coded in ASCII alphanumeric
+characters. For example, the 8-bit binary value 0011-1111 is 3F in
+hexadecimal.  To code this in ASCII, one 8-bit byte containing the ASCII
+code for the character '3' (0011-0011 or 033H) and one 8-bit byte
+containing the ASCII code for the character 'F' (0100-0110 or 046H) are
+required.  For each byte value, the high-order hexadecimal digit is
+always the first digit of the pair of hexadecimal digits.  This
+representation (ASCII hexadecimal) requires twice as ma ny bytes as the
+binary representation.
+A hexadecimal object file is blocked into records, each of which
+contains the record type, length, memory load address and checksum in
+addition to the data.  There are currently six (6) different types of
+records that are defined, not all combinations of these records are
+meaningful, however. The records are:
+
+Data Record (8-, 16-, or 32-bit formats)
+End of File Record (8-, 16-, or 32-bit formats)
+Extended Segment Address Record (16- or 32-bit formats)
+Start Segment Address Record (16- or 32-bit formats)
+Extended Linear Address Record (32-bit format only)
+Start Linear Address Record (32-bit format only)
+
+
+2. General Record Format
+| RECORD  |     LOAD     |         |         |  INFO   |         |
+|  MARK   |    RECLEN    | OFFSET  | RECTYP  |   or    | CHKSUM  |
+|  ':'    |              |         |         |  DATA   |         |
+  1-byte       1-byte      2-bytes   1-byte    n-bytes   1-byte
+
+Each record begins with a RECORD MARK field containing 03AH, the ASCII
+code for the colon (':') character.
+Each record has a RECLEN field which specifies the number of bytes of
+information or data which follows the RECTYP field of the record.  Note
+that one data byte is represented by two ASCII characters.  The maximum
+value of the RECLEN field is hexadecimal 'FF' or 255.
+Each record has a LOAD OFFSET field which specifies the 16-bit starting
+load offset of the data bytes, therefore this field is only used for
+Data Records.  In other records where this field is not used, it should
+be coded as four ASCII zero characters ('0000' or 030303030H).
+Each record has a RECTYP field which specifies the record type of this
+record.  The RECTYP field is used to interpret the remaining information
+within the record.  The encoding for all the current record types are:
+
+'00' Data Record
+'01' End of File Record
+'02' Extended Segment Address Record
+'03' Start Segment Address Record
+'04' Extended Linear Address Record
+'05' Start Linear Address Record
+
+Each record has a variable length INFO/DATA field, it consists of zero
+or more bytes encoded as pairs of hexadecimal digits.  The
+interpretation of this field depends on the RECTYP field.
+Each record ends with a CHKSUM field that contains the ASCII hexadecimal
+representation of the two's complement of  the 8-bit bytes that result
+from converting each pair of ASCII hexadecimal digits to one byte of
+binary, from and including the RECLEN field to and including the last
+byte of the INFO/DATA field.  Therefore, the sum of all the ASCII pairs
+in a record after converting to binary, from the RECLEN field to and
+including the CHKSUM field, is zero.
+
+
+3. Extended Linear Address Record    (32-bit format only)
+| RECORD  |     LOAD     |         |         |         |         |
+|  MARK   |    RECLEN    | OFFSET  | RECTYP  |  ULBA   | CHKSUM  |
+|  ':'    |    '02'      | '0000'  |  '04'   |         |         |
+  1-byte       1-byte      2-bytes   1-byte    2-bytes   1-byte
+
+The 32-bit Extended Linear Address Record is used to specify bits 16-31
+of the Linear Base Address (LBA), where bits 0-15 of the LBA are zero. 
+Bits 16-31 of the LBA are referred to as the Upper Linear Base Address
+(ULBA). The absolute memory address of a content byte in a subsequent
+Data Record is obtained by adding the LBA to an offset calculated by
+adding the LOAD OFFSET field of the containing Data Record to the index
+of the byte in the Data Record (0, 1, 2, ... n).  This offset addition
+is done modulo 4G (i.e., 32-bits), ignoring any carry, so that offset
+wrap-around loading (from OFFFFFFFFH to OOOOOOOOOH) results in wrapping
+around from the end to the beginning of the 4G linear address defined by
+the LBA.  The linear address at which a particular byte is loaded is
+calculated as:
+(LBA + DRLO + DRI) MOD 4G
+where:
+DRLO is the LOAD OFFSET field of a Data Record.
+DRI is the data byte index within the Data Record.
+
+When an Extended Linear Address Record defines the value of LBA, it may
+appear anywhere within a 32-bit hexadecimal object file. This value
+remains in effect until another Extended Linear Address Record is
+encountered.  The LBA defaults to zero until an Extended Linear Address
+Record is encountered.
+The contents of the individual fields within the record are:
+
+RECORD MARK
+This field contains 03AH, the hexadecimal encoding of the ASCII colon
+(':') character.
+
+RECLEN
+The field contains 03032H, the hexadecimal encoding of the ASCII
+characters '02', which is the length, in bytes, of the ULBA data
+information within this record.
+
+LOAD OFFSET
+This field contains 030303030H, the hexadecimal encoding of the ASCII
+characters '0000', since this field is not used for this record.
+
+RECTYP
+This field contains 03034H, the hexadecimal encoding of the ASCII
+character '04', which specifies the record type to be an Extended Linear
+Address Record.
+
+ULBA
+This field contains four ASCII hexadecimal digits that specify the
+16-bit Upper Linear Base Address value.  The high-order byte is the
+10th/llth character pair of the record.  The low-order byte is the
+12th/13th character pair of the record.
+
+CHKSUM
+This field contains the check sum on the RECLEN, LOAD OFFSET, RECTYP,
+and ULBA fields.
+
+
+4. Extended Segment Address Record (16- or 32-bit formats)
+| RECORD  |     LOAD     |         |         |         |         |
+|  MARK   |    RECLEN    | OFFSET  | RECTYP  |  USBA   | CHKSUM  |
+|  ':'    |    '02'      | '0000'  |  '02'   |         |         |
+  1-byte       1-byte      2-bytes   1-byte    2-bytes   1-byte
+
+The 16-bit Extended Segment Address Record is used to specify bits 4-19
+of the Segment Base Address (SBA), where bits 0-3 of the SBA are zero. 
+Bits 4-19 of the SBA are referred to as the Upper Segment Base Address
+(USBA). The absolute memory address of a content byte in a subsequent
+Data Record is obtained by adding the SBA to an offset calculated by
+adding the LOAD OFFSET field of the containing Data Record to the index
+of the byte in the Data Record (0, 1, 2, ... n).  This offset addition
+is done modulo 64K (i.e., 16-bits), ignoring any carry, so that offset
+wraparound loading (from OFFFFH to OOOOOH) results in wrapping around
+from the end to the beginning of the 64K segment defined by the SBA. 
+The address at which a particular byte is loaded is calculated as:
+
+        SBA +  ([DRLO  +  DRI]  MOD  64K)
+
+where:
+        DRLO is the LOAD OFFSET field of a Data Record.
+        DRI is the data byte index within the Data Record.
+
+When an Extended Segment Address Record defines the value of SBA, it
+may appear anywhere within a 16-bit hexadecimal object file.  This
+value remains in effect until another Extended Segment Address
+Record is encountered.  The SBA defaults to zero until an Extended
+Segment Address Record is encountered.
+
+The contents of the individual fields within the record are:
+
+RECORD MARK
+This field contains 03AH, the hexadecimal encoding of the ASCII
+colon (':') character.
+
+RECLEN
+The field contains 03032H, the hexadecimal encoding of the ASCII
+characters '02', which is the length, in bytes, of the USBA data
+information within this record.
+
+LOAD OFFSET
+This field contains 030303030H, the hexadecimal encoding of the
+ASCII characters '0000', since this field is not used for this
+record.
+
+RECTYP
+This field contains 03032H, the hexadecimal encoding of the ASCII
+character '02', which specifies the record type to be an Extended
+Segment Address Record.
+
+USBA
+This field contains four ASCII hexadecimal digits that specify the
+16-bit Upper Segment Base Address value.  The high-order byte is the
+10th/1lth character pair of the record.  The low-order byte is the
+12th/13th character pair of the record.
+
+CHKSUM
+This field contains the check sum on the RECLEN, LOAD OFFSET,
+RECTYP, and USBA fields.
+
+5.    Data Record   (8-, 16-, or 32-bit formats)
+
+| RECORD  |     LOAD     |         |         |         |         |
+|  MARK   |    RECLEN    | OFFSET  | RECTYP  |  DATA   | CHKSUM  |
+|  ':'    |              |         |  '00'   |         |         |
+  1-byte       1-byte      2-bytes   1-byte    n-bytes   1-byte
+
+
+The Data Record provides a set of hexadecimal digits that represent
+the ASCII code for data bytes that make up a portion of a memory
+image.  The method for calculating the absolute address (linear in
+the 8-bit and 32-bit case and segmented in the 16-bit case) for each
+byte of data is described in the discussions of the Extended Linear
+Address Record and the Extended Segment Address Record.
+
+The contents of the individual fields within the record are:
+
+RECORD MARK
+This field contains 03AH, the hexadecimal encoding of the ASCII
+colon (':') character.
+
+RECLEN
+The field contains two ASCII hexadecimal digits that specify the
+number of data bytes in the record.  The maximum value is 'FF' or
+04646H (255 decimal).
+
+LOAD OFFSET
+This field contains four ASCII hexadecimal digits representing the
+offset from the LBA (see Extended Linear Address Record) or SBA (see
+Extended Segment Address Record) defining the address which the
+first byte of the data is to be placed.
+
+RECTYP
+This field contains 03030H, the hexadecimal encoding of the ASCII
+character '00', which specifies the record type to be a Data Record.
+
+DATA
+This field contains pairs of ASCII hexadecimal digits, one pair for
+each data byte.
+
+CHKSUM
+This field contains the check sum on the RECLEN, LOAD OFFSET,
+RECTYP, and DATA fields.
+
+
+6.    Start Linear Address Record  (32-bit format only)
+
+| RECORD  |     LOAD     |         |         |         |         |
+|  MARK   |    RECLEN    | OFFSET  | RECTYP  |  EIP    | CHKSUM  |
+|  ':'    |    '04'      | '0000'  |  '05'   |         |         |
+  1-byte       1-byte      2-bytes   1-byte    4-bytes   1-byte
+
+
+The Start Linear Address Record is used to specify the execution
+start address for the object file.  The value given is the 32-bit
+linear address for the EIP register.  Note that this record only
+specifies the code address within the 32-bit linear address space of
+the 80386.  If the code is to start execution in the real mode of
+the 80386, then the Start Segment Address Record should be used
+instead, since that record specifies both the CS and IP register
+contents necessary for real mode.
+
+The Start Linear Address Record can appear anywhere in a 32-bit
+hexadecimal object file.  If such a record is not present in a
+hexadecimal object file, a loader is free to assign a default start
+address.
+
+The contents of the individual fields within the record are:
+
+RECORD MARK
+This field contains 03AH, the hexadecimal encoding of the ASCII
+colon (':') character.
+
+RECLEN
+The field contains 03034H, the hexadecimal encoding of the ASCII
+characters '04', which is the length, in bytes, of the EIP register
+content within this record.
+
+LOAD OFFSET
+This field contains 030303030H, the hexadecimal encoding of the
+ASCII characters '0000', since this field is not used for this
+record.
+
+RECTYP
+This field contains 03035H, the hexadecimal encoding of the ASCII
+character '05', which specifies the record type to be a Start Linear
+Address Record.
+
+EIP
+This field contains eight ASCII hexadecimal digits that specify the
+32-bit EIP register contents.  The high-order byte is the 10th/1lth
+character pair.
+
+CHKSUM
+This field contains the check sum on the RECLEN, LOAD OFFSET,
+RECTYP, and EIP fields.
+
+
+7.    Start Segment Address Record (16- or 32-bit formats)
+
+| RECORD  |     LOAD     |         |         |         |         |
+|  MARK   |    RECLEN    | OFFSET  | RECTYP  |  CS/IP  | CHKSUM  |
+|  ':'    |    '04'      | '0000'  |  '03'   |         |         |
+  1-byte       1-byte      2-bytes   1-byte    4-bytes   1-byte
+
+
+The Start Segment Address Record is used to specify the execution
+start address for the object file.  The value given is the 20-bit
+segment address for the CS and IP registers.  Note that this record
+only specifies the code address within the 20-bit segmented address
+space of the 8086/80186.
+
+The Start Segment Address Record can appear anywhere in a 16-bit
+hexadecimal object file.   If such a record is not present in a
+hexadecimal object file, a loader is free to assign a default start
+address.
+
+The contents of the individual fields within the record are:
+
+RECORD MARK
+This field contains 03AH, the hexadecimal encoding of the ASCII
+colon (':') character.
+
+RECLEN
+The field contains 03034H, the hexadecimal encoding of the ASCII
+characters '04', which is the length, in bytes, of the CS/IP
+register contents within this record.
+
+LOAD OFFSET
+This field contains 030303030H, the hexadecimal encoding of the
+ASCII characters '0000', since this field is not used for this
+record.
+
+RECTYP
+This field contains 03033H, the hexadecimal encoding of the ASCII
+character '03', which specifies the record type to be a Start
+Segment Address Record.
+
+CS/IP
+This field contains eight ASCII hexadecimal digits that specify the
+16-bit CS register and 16-bit IP register contents.  The high-order
+byte of the CS register content is the 10th/llth character pair, the
+low-order byte is the 12th/13th character pair of the record.  The
+high-order byte of the IP register content is the 14th/15th
+character pair, the low-order byte is the 16th/17th character pair
+of the record.
+
+CHKSUM
+This field contains the check sum on the RECLEN, LOAD OFFSET,
+RECTYP, and CS/IP fields.
+
+
+
+8.   End of File Record  (8-, 16-, or 32-bit formats)

+The End of File Record specifies the end of the hexadecimal object
+file.
+
+The contents of the individual fields within the record are:
+
+RECORD  MARK
+This field contains 03AH, the hexadecimal encoding of the ASCII
+colon (':') character.
+
+RECLEN
+The field contains 03030H, the hexadecimal encoding of the ASCII
+characters '00'.  Since this record does not contain any INFO/DATA
+bytes, the length is zero.
+
+LOAD  OFFSET
+This field contains 030303030H, the hexadecimal encoding of the
+ASCII characters '0000', since this field is not used for this
+record.
+
+RECTYP
+This field contains 03031H, the hexadecimal encoding of the ASCII
+character '01', which specifies the record type to be an End of File
+Record.
+
+CHKSUM
+This field contains the check sum an the RECLEN, LOAD OFFSET, and
+RECTYP fields.  Since all the fields are static, the check sum can
+also be calculated statically, and the value is 04646H, the
+hexadecimal encoding of the ASCII characters 'FF'.

+    -S-Record Format-

+

+        Chaplin@keinstr.uucp (Roger Chaplin) reposted an article written

+   by mcdchg!motmpl!ron (Ron Widell) that explained how Motorola

+   S-Records are formatted.  This comes from a unix man page.  No

+        mention of which version of Unix is specified.  This section

+   of the FAQ is a bit long.  An anonymous ftp archive is currently

+   being sought.  When one is found, the section will be placed in

+   the archive.

+

+

+        SREC(4)                UNIX 5.0 (03/21/84)                SREC(4)

+

+

+        An S-record file consists of a sequence of specially formatted

+   ASCII character strings.  An S-record will be less than or equal to

+   78 bytes in length.

+

+        The order of S-records within a file is of no significance and no

+   particular order may be assumed.

+

+        The general format of an S-record follow:

+

+        +------------------//-------------------//-----------------------+

+        | type | count | address  |            data           | checksum |

+        +------------------//-------------------//-----------------------+

+

+          type      A char-2- field.  These characters describe the

+                    type of record (S0, S1, S2, S3, S5, S7, S8, or

+                    S9).

+          count     A char-2- field.  These characters when paired and

+                    interpreted as a hexadecimal value, display the

+                    count of remaining character pairs in the record.

+

+          address   A char-4,6, or 8- field.  These characters grouped

+                    and interpreted as a hexadecimal value, display

+                    the address at which the data field is to be

+                    loaded into memory.  The length of the field

+                    depends on the number of bytes necessary to hold

+                    the address.  A 2-byte address uses 4 characters,

+                    a 3-byte address uses 6 characters, and a 4-byte

+                    address uses 8 characters.

+          data      A char -0-64- field.  These characters when paired

+                    and interpreted as hexadecimal values represent

+                    the memory loadable data or descriptive

+                    information.

+

+          checksum  A char-2- field.  These characters when paired and

+                    interpreted as a hexadecimal value display the

+                    least significant byte of the ones complement of

+                    the sum of the byte values represented by the

+                    pairs of characters making up the count, the

+                    address, and the data fields.

+

+          Each record is terminated with a line feed.  If any

+          additional or different record terminator(s) or delay

+          characters are needed during transmission to the target

+          system it is the responsibility of the transmitting program

+          to provide them.

+

+          S0 Record  The type of record is 'S0' (0x5330).  The address

+

+

+                     field is unused and will be filled with zeros

+                     (0x0000).  The header information within the data

+                     field is divided into the following subfields.

+

+                                  mname      is char-20- and is the

+                                             module name.

+                                  ver        is char-2- and is the

+                                             version number.

+

+                                  rev        is char-2- and is the

+                                             revision number.

+                                  description is char-0-36- and is a

+                                             text comment.

+

+                     Each of the subfields is composed of ASCII bytes

+                     whose associated characters, when paired,

+                     represent one byte hexadecimal values in the case

+                     of the version and revision numbers, or represent

+                     the hexadecimal values of the ASCII characters

+                     comprising the module name and description.

+

+          S1 Record  The type of record field is 'S1' (0x5331).  The

+                     address field is interpreted as a 2-byte address.

+                     The data field is composed of memory loadable

+                     data.

+          S2 Record  The type of record field is 'S2' (0x5332).  The

+                     address field is interpreted as a 3-byte address.

+                     The data field is composed of memory loadable

+                     data.

+

+          S3 Record  The type of record field is 'S3' (0x5333).  The

+                     address field is interpreted as a 4-byte address.

+                     The data field is composed of memory loadable

+                     data.

+          S5 Record  The type of record field is 'S5' (0x5335).  The

+                     address field is interpreted as a 2-byte value

+                     and contains the count of S1, S2, and S3 records

+                     previously transmitted.  There is no data field.

+

+          S7 Record  The type of record field is 'S7' (0x5337).  The

+                     address field contains the starting execution

+                     address and is interpreted as  4-byte address.

+                     There is no data field.

+          S8 Record  The type of record field is 'S8' (0x5338).  The

+                     address field contains the starting execution

+                     address and is interpreted as  3-byte address.

+                     There is no data field.

+

+          S9 Record  The type of record field is 'S9' (0x5339).  The

+                     address field contains the starting execution

+                     address and is interpreted as  2-byte address.

+                     There is no data field.
