VxWorks 5.5 BSP Developer’s Guide following subsections is required to ensure smooth integration of the BSP into the VxWorks development system. BSP Contents Determining the files and directories that are delivered as part of a BSP product is one of the last and most important steps in creating a BSP. The BSP must include all the files needed to recompile the BSP. It must not contain any files that would cause another BSP to fail to compile on the user’s system. Default Configuration Before beginning the BSP packaging phase, you must establish and set the default configuration for the BSP. This means setting the configuration options in config.h and selecting the default deliverables using the RELEASE variable in the makefile. In some cases, the target board for which the BSP is written may be available in several different configurations. For example, it may be available with different memory modules, peripheral controllers, processor types, or revision levels. One BSP that supports all possible configurations is usually the desired solution. To this end, you are encouraged to configure the final BSP for the default case with the minimum configuration possible. This allows the ROM set and VxWorks image to run, as shipped, on most all variations of the target board. Thus, the default memory size should be the minimum available, and all optional peripheral controllers should be configured out of the BSP. If end users have more memory or an optional module, they can then configure in the appropriate support and rebuild the VxWorks image and VxWorks boot ROMs when necessary. Any BSP configuration mechanisms for tuning target board support should be accessible through parameters in config.h. These parameters are typically either macros or conditional compilation directives. Any uncommon or complex configuration mechanisms should be explained fully in config.h and in the SPECIAL CONSIDERATIONS section of target.nr. The standard delivered makefile targets for Wind River BSPs include bootrom, vxWorks, and vxWorks.st. The standard make variable RELEASE is defined to be these targets. If a different set of targets (say, bootrom_uncmp.hex instead of bootrom.hex) is to be delivered, RELEASE should be redefined in the makefile. For example: 196
10 Product Packaging ... include $(TGT_DIR)/h/make/defs.$(WIND_HOST_TYPE) ... RELEASE +=bootrom_uncmp.hex ... include $(TGT_DIR)/h/make/rules.bsp ... The purpose of delivering executable images to the customer is for demonstration and verification only. It is presumed that all customers will reconfigure and rebuild all executables in-house. This includes boot ROM images. Projects for the supported toolchains should also be delivered. The default name for these projects is bspName_gnu or bspName_diab. Third parties may use other naming schemes. These projects are built by default with the RELEASE macro. They can be built individually by using the make targets prj_gnu or prj_diab. 10 Included Files For details on the files included in a BSP product, see M. BSP Product Contents. BSP files fall into these categories: ■ Target-specific files: all files in the target/config/bspname and target reference page entries in the docs/vxworks/bsp/bspName directory. ■ ■ Files associated with the default projects generated from the BSP. This project can be created from the project facility or from the traditional command line using make release. Documentation files using HTML format. See the reference entry for the htmlBook command (Tornado User’s Guide: Utilities Reference). Excluded Files The following files should not be delivered with a BSP product: ■ VxWorks Files The product should not include any files that are provided to the user by any other Wind River product. target/config/all/.... target/config/comps/... target/src/... target/h/... 197
