S-Record handling
-DESCRIPTION
-
+ DESCRIPTION
+
Ordinary S-Records cannot hold anything but addresses and
data, so that's all that we implement.
-
+
The only interesting thing is that S-Records may come out of
order and there is no header, so an initial scan is required
to discover the minimum and maximum addresses used to create
the vma and size of the only section we create. We
- arbitrarily call this section ".text".
+ arbitrarily call this section ".text".
When bfd_get_section_contents is called the file is read
again, and this time the data is placed into a bfd_alloc'd
up and output them when it's time to close the bfd.
An s record looks like:
-
-EXAMPLE
+
+ EXAMPLE
S<type><length><address><data><checksum>
-
-DESCRIPTION
+
+ DESCRIPTION
Where
o length
is the number of bytes following upto the checksum. Note that
7) four byte address termination record
8) three byte address termination record
9) two byte address termination record
-
+
o address
is the start address of the data following, or in the case of
a termination record, the start address of the image
is the sum of all the raw byte data in the record, from the length
upwards, modulo 256 and subtracted from 255.

Symbol S-Record handling
-DESCRIPTION
+ DESCRIPTION
Some ICE equipment understands an addition to the standard
S-Record format; symbols and their addresses can be sent
before the data.
so a short symbol table could look like:
-EXAMPLE
+ EXAMPLE
$$ flash.x
$$ flash.c
_port6 $0
_etext $8036
_edata $8036
_end $8036
- $$
+ $$
-DESCRIPTION
+ DESCRIPTION
We allow symbols to be anywhere in the data stream - the module names
- are always ignored.
-
-*/
+ are always ignored. */
