| 23 | SUBSECTION |
| 24 | Tektronix Hex Format handling |
| 25 | |
| 26 | DESCRIPTION |
| 27 | |
| 28 | Tek Hex records can hold symbols and data, but not |
| 29 | relocations. Their main application is communication with |
| 30 | devices like PROM programmers and ICE equipment. |
| 31 | |
| 32 | It seems that the sections are descibed as being really big, |
| 33 | the example I have says that the text section is 0..ffffffff. |
| 34 | BFD would barf with this, many apps would try to alloc 4GB to |
| 35 | read in the file. |
| 36 | |
| 37 | Tex Hex may contain many sections, but the data which comes in |
| 38 | has no tag saying which section it belongs to, so we create |
| 39 | one section for each block of data, called "blknnnn" which we |
| 40 | stick all the data into. |
| 41 | |
| 42 | TekHex may come out of order and there is no header, so an |
| 43 | initial scan is required to discover the minimum and maximum |
| 44 | addresses used to create the vma and size of the sections we |
| 45 | create. |
| 46 | We read in the data into pages of CHUNK_MASK+1 size and read |
| 47 | them out from that whenever we need to. |
| 48 | |
| 49 | Any number of sections may be created for output, we save them |
| 50 | up and output them when it's time to close the bfd. |
| 51 | |
| 52 | |
| 53 | A TekHex record looks like: |
| 54 | EXAMPLE |
| 55 | %<block length><type><checksum><stuff><cr> |
| 56 | |
| 57 | DESCRIPTION |
| 58 | Where |
| 59 | o length |
| 60 | is the number of bytes in the record not including the % sign. |
| 61 | o type |
| 62 | is one of: |
| 63 | 3) symbol record |
| 64 | 6) data record |
| 65 | 8) termination record |
| 66 | |
| 67 | |
| 68 | The data can come out of order, and may be discontigous. This is a |
| 69 | serial protocol, so big files are unlikely, so we keep a list of 8k chunks |
