- S-record handling
+ S-Record handling
DESCRIPTION
- 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
+ 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
An s record looks like:
EXAMPLE
- S<
length><type><address><data><checksum>
+ S<
type><length><address><data><checksum>
DESCRIPTION
Where
o checksum
is the sum of all the raw byte data in the record, from the length
upwards, modulo 256 and subtracted from 255.

+
+
+SUBSECTION
+ Symbol S-Record handling
+
+DESCRIPTION
+ Some ICE equipment understands an addition to the standard
+ S-Record format; symbols and their addresses can be sent
+ before the data.
+
+ The format of this is:
+ ($$ <modulename>
+ (<space> <symbol> <address>)*)
+ $$
+
+ so a short symbol table could look like:
+
+EXAMPLE
+ $$ flash.x
+ $$ flash.c
+ _port6 $0
+ _delay $4
+ _start $14
+ _etext $8036
+ _edata $8036
+ _end $8036
+ $$
+
+DESCRIPTION
+ We allow symbols to be anywhere in the data stream - the module names
+ are always ignored.
