24 | S-Record handling |
25 | |
26 | DESCRIPTION |
27 | |
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: |
45 | |
46 | EXAMPLE |
47 | S<type><length><address><data><checksum> |
48 | |
49 | DESCRIPTION |
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 |
64 | |
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. |
73 | |
74 | SUBSECTION |
75 | Symbol S-Record handling |
76 | |
77 | DESCRIPTION |
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 | |
89 | EXAMPLE |
90 | $$ flash.x |
91 | $$ flash.c |
92 | _port6 $0 |
93 | _delay $4 |
94 | _start $14 |
95 | _etext $8036 |
96 | _edata $8036 |
97 | _end $8036 |
98 | $$ |
99 | |
100 | DESCRIPTION |
101 | We allow symbols to be anywhere in the data stream - the module names |
102 | are always ignored. */ |
