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

77 | Symbol S-Record handling |
78 | ||
116c20d2 | 79 | DESCRIPTION |
252b5132 RH |
80 | Some ICE equipment understands an addition to the standard |
81 | S-Record format; symbols and their addresses can be sent | |
82 | before the data. | |
83 | ||
84 | The format of this is: | |
85 | ($$ <modulename> | |
86 | (<space> <symbol> <address>)*) | |
87 | $$ | |
88 | ||
89 | so a short symbol table could look like: | |
90 | ||
116c20d2 | 91 | EXAMPLE |
252b5132 RH |
92 | $$ flash.x |
93 | $$ flash.c | |
94 | _port6 $0 | |
95 | _delay $4 | |
96 | _start $14 | |
97 | _etext $8036 | |
98 | _edata $8036 | |
99 | _end $8036 | |
100 | $$ | |
101 | ||
116c20d2 | 102 | DESCRIPTION |
252b5132 | 103 | We allow symbols to be anywhere in the data stream - the module names |
116c20d2 | 104 | are always ignored. */ |
