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 prob-
lematic; 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.
