VxWorks 5.5 BSP Developer’s Guide sysNet.c bspname.h Optional setup and initialization for network interface devices. Use bspname.h to set all non-optional, board-specific information as defined in this file, including definitions for the serial interface, timer, and I/O devices. The directory target/h/drv is where much of the information is located. The header files of the drivers needed to port VxWorks to your board should be included at the beginning of bspname.h. This file is intended for constant information that is not subject to user configuration. If any macros or values defined in bspname.h can be changed to customize the system, then define those macros or values in config.h instead. It is helpful to use a sample header file, because most constant names, basic device addresses, and so on are already defined and just require refinement. The following should be defined in bspname.h: ■ interrupt vectors/levels ■ I/O device addresses ■ the meaning of the device register bits ■ system and auxiliary clock parameters (maximum and minimum rates) Also, use a board description macro prefix (for example, Heurikon is defined as HK_) to indicate values that are board-specific. Interrupt Vectors and Levels. Define all interrupt vectors and levels dictated by hardware and not user changeable in bspname.h. I/O Device Addresses. Define all I/O addresses fixed by hardware or otherwise not user-changeable in bspname.h. Meaning of Device Register Bits. For on-board control registers, define a macro value for each bit or group of bits in each registers. Typically, such macro definitions are placed in bspname.h if there is no better location for them. System and Auxiliary Clocks. When given a new clock rate, the timer drivers use these macros to determine if the new rate is valid: SYS_CLK_RATE_MIN SYS_CLK_RATE_MAX AUX_CLK_RATE_MIN AUX_CLK_RATE_MAX Sets the minimum system clock rate. Sets the maximum system clock rate. Sets the minimum auxiliary clock rate. Sets the maximum auxiliary clock rate. 26
2 BSP Organization target.nr The file target.nr, located in the target/config/bspname directory, contains board-specific information necessary to run VxWorks. To provide a convenient starting point for a new BSP, the BSP Porting Kit CD-ROM includes several architecture-specific templates, such as target/config/template68k/target.nr. For Tornado 2.x, the target.nr file is not processed as a UNIX-style reference page or Windows-compatible text page. It is delivered to the customer as an HTML file. Refer to L. Refgen for details on the refgen documentation utility. This reference entry is divided into the following sections: NAME The name of the board. INTRODUCTION Summary of scope and assumptions. Instructions concerning boot ROMs and necessary jumper settings. FEATURES Summary of all supported and unsupported features of the board. HARDWARE DETAILS Summary of available devices, for example, serial, Ethernet, and SCSI. SPECIAL CONSIDERATIONS Special features or restrictions. BOARD LAYOUT An ASCII representation of the board, useful for illustrating boot ROMs and jumpers. Jumpers and jumper states are represented by the characters shown in Table 2-2. SEE ALSO References to other relevant VxWorks manuals. BIBLIOGRAPHY Summary of data sheets and other sources of technical information pertinent to the board and devices. 2 27
