23 | Tektronix Hex Format handling |
24 | |
25 | DESCRIPTION |
26 | |
27 | Tek Hex records can hold symbols and data, but not |
28 | relocations. Their main application is communication with |
29 | devices like PROM programmers and ICE equipment. |
30 | |
31 | It seems that the sections are described as being really big, |
32 | the example I have says that the text section is 0..ffffffff. |
33 | BFD would barf with this, many apps would try to alloc 4GB to |
34 | read in the file. |
35 | |
36 | Tex Hex may contain many sections, but the data which comes in |
37 | has no tag saying which section it belongs to, so we create |
38 | one section for each block of data, called "blknnnn" which we |
39 | stick all the data into. |
40 | |
41 | TekHex may come out of order and there is no header, so an |
42 | initial scan is required to discover the minimum and maximum |
43 | addresses used to create the vma and size of the sections we |
44 | create. |
45 | We read in the data into pages of CHUNK_MASK+1 size and read |
46 | them out from that whenever we need to. |
47 | |
48 | Any number of sections may be created for output, we save them |
49 | up and output them when it's time to close the bfd. |
50 | |
51 | A TekHex record looks like: |
52 | EXAMPLE |
53 | %<block length><type><checksum><stuff><cr> |
54 | |
55 | DESCRIPTION |
56 | Where |
57 | o length |
58 | is the number of bytes in the record not including the % sign. |
59 | o type |
60 | is one of: |
61 | 3) symbol record |
62 | 6) data record |
63 | 8) termination record |
64 | |
65 | The data can come out of order, and may be discontigous. This is a |
66 | serial protocol, so big files are unlikely, so we keep a list of 8k chunks. */ |
