srec_brecord(5)		      File Formats Manual	       srec_brecord(5)

NAME
       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 hexa-
       decimal	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 problematic; 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.
