VxWorks 5.5 BSP Developer’s Guide ■ Create a BSP product. This applies only to customers who intend to distribute their BSP to other Wind River customers. See A.4 Product Contents, p.205 for information on how to package a BSP product for delivery to customers. A.2 Code Interface Changes None of the standard APIs used in BSPs have been changed since Tornado 1.0.1. The Tornado Release Notes, 2.0, mentions changes to the API for pciConfigLib and access mechanism 0; however, these modifications should affect very few customers, if any at all. The version numbers of Wind River BSPs have been updated to version 1.2 as a result of changes to product packaging. Wind River uses a BSP identification scheme of the form X.X/Y, where X.X is the BSP version identification, and Y is the revision ID. The revision ID is incremented by one each time a BSP is updated or re-released. The first revision number for any new BSP is zero (0), not one (1). The config.h file includes the macro BSP_REV, which is a string indicating the revision number of the BSP, for example: #define BSP_VER_1_2 1 #define BSP_VER_1_1 1 #define BSP_VERSION "1.2" /* A Tornado 2.0 BSP */ #define BSP_REV "/0" /* First Tornado 2.0 revision */ The config.h file also declares the BSP version number in both string and macro form. The BSP_VERSION macro is a string, for example “1.2”. The macro BSP_VER_1_2 is defined to be the integer 1 and can be used in both #if and #ifdef expressions. Since version 1.2 BSPs are otherwise compatible with version 1.1 BSPs, the macro BSP_VER_1_1 can also be defined. At the end of config.h, add directives that #include the project parameters header file when building from the project facility. #if defined(PRJ_BUILD) # include "prjParams.h" #endif 204
A Upgrading a BSP for Tornado 2.0 A.3 Project Issues The project facility is the major difference between Tornado 1.0.1 and Tornado 2.0. For command-line operations, there is no difference between a Tornado 1.0.1 and a Tornado 2.0 BSP. In Tornado 2.0, project builds are completely new, and they do not involve files in target/config/all. The old usrConfig.c file has been pulled apart into initialization groups and component configlettes, which are compiled and linked together by the project build mechanism. Building with the project facility differs greatly from building from the command line. Building from the command line uses the BSP Makefile as well as the config.h and configAll.h header files to control most of the configuration of the object being built. When building from the project facility, the configuration is determined by the project header files instead. Project building does not involve the BSP makefile. If there is an item in config.h or configAll.h that is described to the project facility through a CDF file, that item is controlled solely by the project information; changes to config.h and configAll.h do not affect it, nor do they affect an existing project. Note, if there is something in config.h or configAll.h that the project tool is not aware of, then the config.h and configAll.h selections will prevail during project builds. There are two methods for generating a default project from a BSP ■ Invoke the project facility wizard. To open the wizard, select the File>New Project command from the menubar, or, if the Create Project or Open Workspace window is open, select the New tab. ■ Use the command line, as follows: A make release A.4 Product Contents The most obvious change for version 1.2 BSPs is the product contents list, which is provided in M. BSP Product Contents. In Tornado 1.0.1, each BSP product carried a large number of driver files that were also delivered as part of the base Tornado product. This redundancy caused problems for customers, who were uncertain what version of a file was being used. 205
