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
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
(d)[0] = digs[((x)>>4)&0xf];
