NAME

6       srec_mips_flash - MIPS‐Flash file format
7

DESCRIPTION

9       The  MIPS  SDE  tool chain has a convert program that is able to output
10       this format.  I have no idea what reads it, some kind of flash program‐
11       mer I suppose.
12
13   Format
14       The  file must start with '!R' to reset the state machine.  White space
15       appears to be ignored, except as it serves to separate tokens.
16
17       Data is presented as 32‐bit hexadecimal numbers,  in  the  normal  big‐
18       endian  text  number format.  To write them to memory, you have to know
19       if the target is big‐endian or little‐endian. for  little  endian  tar‐
20       gets, reverse the order of the bytes in this number.
21
22       The  eight  bytes  following a '>' are a sort of comment.  The SDE code
23       reads like they are displayed in the flash  programmer  as  a  kind  of
24       progress indicator.
25
26       The number following '@' is a new address for the following data.
27
28       Each segment must be erased before it can be written, this is done with
29       the '!E' command.  Each segment is assumed to be 128kB in size.
30
31       Special segments must unlocked (with the '!C' command) and locked again
32       (with the '!S' command).
33
34       This file format contains no checksum mechanism.
35
36   Command Line Options
37       This  format  is  specified  using one of the -Mips‐Flash‐Big_Endian or
38       -Mips‐Flash‐Little_Endian options.  The endian‐ness must  be  specified
39       on  the  command line, because there is nothing in the file contents to
40       indicate the endian‐ness of the data it contains.
41
42   Size Multiplier
43       In general, binary data will expand in sized by approximately 2.3 times
44       when represented with this format (worse if you use shorter lines).

EXAMPLE

47       Here  is  an  example  MIPS‐Flash  file.   It contains the data “Hello,
48       World” to be loaded at bytes address 0x0000  (but  remember,  the  file
49       contents are always multiples of four bytes).
50              !R
51              >00000xxx @00000000 !E
52              @00000000
53              >00000000
54              48656C6C 6F2C2057 6F726C64 210A0000
55              >#DL_DONE
56              >FINISHED
