The Tool Suite
The tool suite contains two assemblers: one for the 218x and it's predecessors and one for the 219x; a linker; and a loader for the 2181 EZ-Kit LiteTM. The assemblers expect input conforming to version 7 syntax and later of the Analog Devices tools. There are notes in the man pages about converting from pre version 7 syntax.Notes
- The assemblers support most of the latest syntax except for the .import directive, structure support, repeat sequences, the .type directive, and the .weak directive;
- the linker in general only supports enough of the syntax to be useful (it does not support overlays); and
- The test platforms are:
- ADSP-2181 EZ-LAB; and
- STUD-1 2191 donnated by the Division of Signal Processing, Luleå University of Technology, Sweden and Rubico AB, Sweden.
- The ez21 loader supports loading to both of these platforms.
