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
       hexadecimal  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[rq] to be loaded at address 0.
