|
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.
|
|
|
|
Tex Hex may contain many sections, but the data which comes in
|
|
has no tag saying which section it belongs to, so we create
|
|
one section for each block of data, called "blknnnn" which we
|
|
stick all the data into.
|
|
|
|
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.
|
|
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
|
|
is the number of bytes in the record not including the % sign.
|
|
o type
|
|
is one of:
|
|
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
