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

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