The rest of this section summarizes BSP files and directories. 2.2.1 BSP Source and Include Files This section describes the directories target/config/all and target/config/bspname. Strictly speaking, the files in target/config/all are not part of the BSP, but the modules defined there are shared by all BSPs. Familiarity with these modules is essential if you want to understand your particular BSP. When building project images, the component configlettes in target/config/comps/src replace the files in target/config/all.Aconfiglette is any C source code compiled by the project facility as a part of the project build step. Such files provide only some limited part of the final project configuration. 12
2 BSP Organization Files in the target/config/all Directory The files in target/config/all are delivered as part of the VxWorks architecture product. Do not alter these files unless absolutely necessary. Of special concern is configAll.h. This file sets the default configuration for all VxWorks images. The values you define here should be generic and therefore true for most if not all VxWorks developers at your site. If you need a VxWorks image that differs from the default configuration, use your BSP’s config.h to override (#define or #undef) the default values in configAll.h. Files in config/all are not directly used when building a project. They are scanned only once when a new project is made from a BSP. Any changes to the files in target/config/all after a project has been created do not affect the project. If a change is desired, the user must make the change directly in the project area. 2 ! CAUTION: Changing configAll.h from the command line can have unpleasant side effects for other VxWorks users at your site. This note only applies to building from the command line. One benefit of the Tornado project facility is that changes do not affect existing projects. Only new projects created from a BSP after the change to configAll.h inherit that change. bootConfig.c – Main Initialization for Boot ROM Images The bootConfig.c file is the main initialization and control file for all boot ROM images. It includes the complete boot ROM shell task. It contains a table (NETIF) for network device initialization. This module is a subset of usrConfig.c. Boot ROM images do not provide all of the optional features available in the full VxWorks images. Of particular note is that boot images do not use MMU libraries (except for SPARC). The Tornado project facility does not have the ability to create and manipulate a boot ROM project. For projects created from a BSP, there is a button that performs the traditional command-line creation of a boot ROM image from the Build menu. Please take note that project-specific configuration information has no effect at all when the boot ROM image gets built. Only the traditional config.h, configAll.h, bootConfig.c, and bootInit.c files affect the building of a boot ROM image. bootInit.c – Second-Stage ROM Initialization The bootInit.c file is the second stage of boot ROM initialization, after romInit.o. The romInit( ) routine in romInit.s terminates by jumping to romStart( ), defined in this file. The routine romStart( ) performs the necessary code uncompression and relocation for ROM images. First it copies the text and data segments from 13
