| 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. */ |
