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 + % + +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.
