BSP Developer’s Guide, 6.0

Before describing the steps in the boot process, it is worth noting the files you must

write or modify during BSP development. Most of the work involved in

developing a BSP is accomplished by writing the following three routines:

■

romInit( ) in romInit.s - initializes the CPU and memory

■

sysHwInit( ) in sysLib.c - ensures that all board hardware is initialized to a

quiescent state

■

sysHwInit2( ) in sysLib.c - further prepares the board hardware for use with

VxWorks applications

A comprehensive list of the routines required in every BSP is provided in

2.3.4 Required Routines, p.32.

The following BSP files, device driver directories, and configuration directories are

common to most BSPs:

Required BSP Files:

target/config/bspname/bspname.h

target/config/bspname/config.h

target/config/bspname/Makefile

target/config/bspname/README

target/config/bspname/romInit.s

target/config/bspname/sysALib.s

target/config/bspname/sysLib.c

target/config/bspname/target.ref (or target.nr)

Optional BSP Files

target/config/bspname/sysSerial.c

target/config/bspname/configNet.h

target/config/bspname/sysEnd.c

Device Driver Directories:

target/src/drv/end

target/src/drv/hdisk

target/src/drv/intrCtl
