SUBSECTION
Tektronix Hex Format handling
DESCRIPTION
-
+
Tek Hex records can hold symbols and data, but not
relocations. Their main application is communication with
devices like PROM programmers and ICE equipment.
-
+
It seems that the sections are descibed as being really big,
the example I have says that the text section is 0..ffffffff.
BFD would barf with this, many apps would try to alloc 4GB to
- read in the file.
+ read in the file.
Tex Hex may contain many sections, but the data which comes in
has no tag saying which section it belongs to, so we create
TekHex 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 sections we
- create.
+ create.
We read in the data into pages of CHUNK_MASK+1 size and read
them out from that whenever we need to.
Any number of sections may be created for output, we save them
up and output them when it's time to close the bfd.
-
A TekHex record looks like:
EXAMPLE
%<block length><type><checksum><stuff><cr>
-
+
DESCRIPTION
Where
o length
3) symbol record
6) data record
8) termination record
-
The data can come out of order, and may be discontigous. This is a
serial protocol, so big files are unlikely, so we keep a list of 8k chunks
