24 | S-Record handling |
25 | ||
116c20d2 | 26 | DESCRIPTION |
7b82c249 | 27 | |
252b5132 RH |
28 | Ordinary S-Records cannot hold anything but addresses and |
29 | data, so that's all that we implement. | |
30 | ||
31 | The only interesting thing is that S-Records may come out of | |
32 | order and there is no header, so an initial scan is required | |
33 | to discover the minimum and maximum addresses used to create | |
34 | the vma and size of the only section we create. We | |
35 | arbitrarily call this section ".text". | |
36 | ||
37 | When bfd_get_section_contents is called the file is read | |
38 | again, and this time the data is placed into a bfd_alloc'd | |
39 | area. | |
40 | ||
41 | Any number of sections may be created for output, we save them | |
42 | up and output them when it's time to close the bfd. | |
43 | ||
44 | An s record looks like: | |
7b82c249 | 45 | |
116c20d2 | 46 | EXAMPLE |
252b5132 | 47 | S<type><length><address><data><checksum> |
7b82c249 | 48 | |
116c20d2 | 49 | DESCRIPTION |
252b5132 RH |
50 | Where |
51 | o length | |
52 | is the number of bytes following upto the checksum. Note that | |
53 | this is not the number of chars following, since it takes two | |
54 | chars to represent a byte. | |
55 | o type | |
56 | is one of: | |
57 | 0) header record | |
58 | 1) two byte address data record | |
59 | 2) three byte address data record | |
60 | 3) four byte address data record | |
61 | 7) four byte address termination record | |
62 | 8) three byte address termination record | |
63 | 9) two byte address termination record | |
7b82c249 | 64 | |
252b5132 RH |
65 | o address |
66 | is the start address of the data following, or in the case of | |
67 | a termination record, the start address of the image | |
68 | o data | |
69 | is the data. | |
70 | o checksum | |
71 | is the sum of all the raw byte data in the record, from the length | |
72 | upwards, modulo 256 and subtracted from 255. | |

75 | Symbol S-Record handling |
76 | ||
116c20d2 | 77 | DESCRIPTION |
252b5132 RH |
78 | Some ICE equipment understands an addition to the standard |
79 | S-Record format; symbols and their addresses can be sent | |
80 | before the data. | |
81 | ||
82 | The format of this is: | |
83 | ($$ <modulename> | |
84 | (<space> <symbol> <address>)*) | |
85 | $$ | |
86 | ||
87 | so a short symbol table could look like: | |
88 | ||
116c20d2 | 89 | EXAMPLE |
252b5132 RH |
90 | $$ flash.x |
91 | $$ flash.c | |
92 | _port6 $0 | |
93 | _delay $4 | |
94 | _start $14 | |
95 | _etext $8036 | |
96 | _edata $8036 | |
07d6d2b8 | 97 | _end $8036 |
252b5132 RH |
98 | $$ |
99 | ||
116c20d2 | 100 | DESCRIPTION |
252b5132 | 101 | We allow symbols to be anywhere in the data stream - the module names |
116c20d2 | 102 | are always ignored. */ |
