This section provides an overview of generating libraries and drivers. The hardware specification file and the MSS files define a system. For each processor in the system, the tool finds the list of addressable peripherals. For each processor, a unique list of drivers and libraries are built. The tool does the following for each processor:

  • Builds the directory structure, as defined in Output Files.
  • Copies the necessary source files for the drivers, OSs, and libraries into the processor instance specific area: OUTPUT_DIR/processor_instance_name/libsrc.
  • Calls the Design Rule Check (DRC) procedure, which is defined as an option in the MDD or MLD file, for each of the drivers, OSs, and libraries visible to the processor.
  • Calls the generate Tcl procedure (if defined in the Tcl file associated with an MDD or MLD file) for each of the drivers, OSs, and libraries visible to the processor. This generates the necessary configuration files for each of the drivers, OSs, and libraries in the include directory of the processor.
  • Calls the post_generate Tcl procedure (if defined in the Tcl file associated with an MDD or MLD file) for each of the drivers, OSs, and libraries visible to the processor.
  • Runs make (with targets include and libs) for the OSs, drivers, and libraries specific to the processor. On the Linux platform, the gmake utility is used, while on NT platforms, make is used for compilation.
  • Calls the execs_generate Tcl procedure (if defined in the Tcl file associated with an MDD or MLD file) for each of the drivers, OSs, and libraries visible to the processor.
