6 srec_ti_tagged - Texas Instruments Tagged (SDSMAC) file format
7
9 This format is also known as the TI‐Tagged or TI‐SDSMAC format.
10 This format allows binary files to be uploaded and downloaded between
12 two computer systems, typically between a computer system (such as a
13 PC, Macintosh, or workstation) and an emulator or evaluation board for
14 microcontrollers and microprocessors.
15 The Lines
17 Unlike many other object formats, the lines themselves are not espe‐
18 cially significant. The format consits of a number of tagged fields,
19 and lines are composed of a series of these fields.
20 Tag Description
22 ─────────────────────────────────
23 * Data byte.
24 : End of file.
25 0 File header (optional).
26 7 Checksum.
27 8 Dummy checksum (ignored).
28 9 Address.
29 B Data word.
30 F End of data record.
31 K Program identifier
32 (optional).
33 Data Byte
35 ┌──┬───┬───┐
36 │B │ n │ n │
37 One byte of data. The nn is 8└‐─b─i┴t──b─i┴g─‐─e─n┘dian hexadecimal.
38 End of File
40 ┌──┬──────┐
41 │: │ CRLF │
42 The end of data is indicated b└y──t┴h─i─s──t─a─g┘. The end of line sequence (LF
43 on Unix systems, CRLF on PCs) follows this tag.
44 File Header
46 ┌──┬────────┬──────────┐
47 │0 │ length │ filename │
48 The optional start‐of‐fi└l─e─┴r─e─c─o─r─d──b─e┴g─i─n─s──w─i─t─h──a┘tag character ('0') and
49 a 12‐character file header. The first four characters are the byte
50 count of the file data. The remaining 8 characters are the name of the
51 file and may be any ASCII characters, blank padded.
52 Checksum
54 ┌──┬───┬───┬───┬───┐
55 │7 │ n │ n │ n │ n │
56 The checksum is the 2s└──c┴o─m─p─l┴e─m─e─n┴t──s─u┴m──o─f┘the 8‐bit ASCII values of
57 characters, beginning with the first tag character and ending with the
58 checksum tag character (7). The nnnn is 16‐bit big‐endian hexadecimal.
59 Dummy Checksum
61 ┌──┬───┬───┬───┬───┐
62 │8 │ n │ n │ n │ n │
63 The checksum is the 2s└──c┴o─m─p─l┴e─m─e─n┴t──s─u┴m──o─f┘the 8‐bit ASCII values of
64 characters, beginning with the first tag character and ending with the
65 checksum tag character (8). The nnnn is 16‐bit big‐endian hexadecimal.
66 Address
68 ┌──┬───┬───┬───┬───┐
69 │9 │ n │ n │ n │ n │
70 Addresses may be given f└o─r─┴a─n─y─┴d─a─t─a┴─b─y─t┴e─,──b┘ut none is mandatory. The
71 file begins at 0000 if no address is given before the first data field.
72 The nnnn is 16‐bit big‐endian hexadecimal.
73 Data Word
75 ┌──┬───┬───┬───┬───┐
76 │B │ a │ a │ b │ b │
77 Two bytes of data. The └a─a─┴a─n─d─┴b─b──a┴r─e──e┴a─c─h─┘8‐bit big‐endian hexadeci‐
78 mal.
79 End of Record
81 ┌──┬──────┐
82 │F │ CRLF │
83 The end of line sequence (LF o└n──U┴n─i─x──s─y─s┘tems, CRLF on PCs) is escaped
84 using this tag. The checksum is reset to zero at this point.
85 Program Identifier
87 ┌──┬───┬───┬───┬───┬──────┐
88 │K │ n │ n │ n │ n │ text │
89 The program identifie└r──c┴a─n──c┴o─n─t─a┴i─n──a┴─b─r─i┴e─f──d─e─s─c┘ription of the program,
90 or can be empty (i.e. the text portion is optional). The nnnn length
91 (hex) of the field includes the `K', the length and the text; it is at
92 least 5.
93 Size Multiplier
95 In general, binary data will expand in sized by approximately 2.9 times
96 when represented with this format.

99 Here is an example TI‐Tagged file. It contains the data “Hello,
100 World[rq] to be loaded at address 0x0100.
