Hi Matthew, There is also a program called "elfspl21k.exe" in VisualDSP package. With this program you can split the *.DXE file into an easily read byte-stack ASCII format file. You can extract each segment seperately from the DXE file. The byte-stack format consists basically of a header (data address and data size and data word width info) and the data (ASCII hex dump). For info on the splitter and the byte stack file format see the online manuals of VisualDSP (or on the web: http://www.analog.com/publications/documentation/VisualDSP/release41/lin ker/splitter.pdf for the splitter program, and http://www.analog.com/publications/documentation/VisualDSP/release41/lin ker/formats.pdf for the byte stack file format).
