8f8fefcc | 23 | S-Record handling |
4a81b561 | 24 | |
9898b929 JG |
25 | DESCRIPTION |
26 | ||
8f8fefcc JG |
27 | Ordinary S-Records cannot hold anything but addresses and |
28 | data, so that's all that we implement. | |
9783e04a | 29 | |
8f8fefcc | 30 | The only interesting thing is that S-Records may come out of |
9898b929 JG |
31 | order and there is no header, so an initial scan is required |
32 | to discover the minimum and maximum addresses used to create | |
33 | the vma and size of the only section we create. We | |
9783e04a | 34 | arbitrarily call this section ".text". |
9898b929 JG |
35 | |
36 | When bfd_get_section_contents is called the file is read | |
37 | again, and this time the data is placed into a bfd_alloc'd | |
38 | area. | |
39 | ||
40 | Any number of sections may be created for output, we save them | |
41 | up and output them when it's time to close the bfd. | |
42 | ||
43 | An s record looks like: | |
44 | ||
45 | EXAMPLE | |
294eaca4 | 46 | S<type><length><address><data><checksum> |
9898b929 JG |
47 | |
48 | DESCRIPTION | |
49 | Where | |
50 | o length | |
51 | is the number of bytes following upto the checksum. Note that | |
52 | this is not the number of chars following, since it takes two | |
53 | chars to represent a byte. | |
54 | o type | |
55 | is one of: | |
56 | 0) header record | |
57 | 1) two byte address data record | |
58 | 2) three byte address data record | |
59 | 3) four byte address data record | |
60 | 7) four byte address termination record | |
61 | 8) three byte address termination record | |
62 | 9) two byte address termination record | |
63 | ||
64 | o address | |
65 | is the start address of the data following, or in the case of | |
66 | a termination record, the start address of the image | |
67 | o data | |
68 | is the data. | |
69 | o checksum | |
70 | is the sum of all the raw byte data in the record, from the length | |
71 | upwards, modulo 256 and subtracted from 255. | |

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 | |
9783e04a | 98 | $$ |
8f8fefcc JG |
99 | |
100 | DESCRIPTION | |
101 | We allow symbols to be anywhere in the data stream - the module names | |
102 | are always ignored. | |
