The src Directory

This src directory must contain the following two files:

• Project.tmpl

• Imakefile

It also contains the following directories:

• boot (see "The boot Directory")

• dbg (see "The dbg Directory")

• reboot (see "The reboot Directory")

The Project.tmpl file is used to produce a makefile to build your new BSP component (see ChorusOSMkMf(1CC)).

Example 3-4 New BSP: Project.tmpl

#include "Package.rules"

SRC_DIR         = SourceDir
BUILD_DIR       = BuildDir
DIST_DIR        = DistDir

VPATH           = $(SRC_DIR)$(REL_DIR)

WARN            = $(WARN_ON)

MYBSP_DIST_BIN  = $(DIST_DIR)/bin/mybsp

DRV_DIST_BIN    = $(DRV_DIR)/bin/drv

INCLUDES        = -I$(NUCLEUS_DIR)/include/chorus \
                  -I$(NUCLEUS_DIR)/include/stdc   \
                  -I$(DRV_DIR)/include/chorus \
                  -I$(DIST_DIR)/include/chorus \
                  -I$(SRC_DIR)$(REL_DIR)

BSP_LIBS        = $(NUCLEUS_DIR)/lib/boot_tools/boot_tools.s.a \
                  $(NUCLEUS_DIR)/lib/util/util.s.a \
                  $(NUCLEUS_DIR)/lib/bki/bki.s.a \
                  $(NUCLEUS_DIR)/lib/cpu/cpu.s.a \
                  $(NUCLEUS_DIR)/lib/stdc/stdc.s.a \
                  $(NUCLEUS_DIR)/lib/boot_tools/sys/sys.s.a 

The MYBSP_DIST_BIN variable defines the directory which programs will be exported to. The name mybsp can be changed to the real board name. The DIST_DIR variable is defined by the path given with the -d option of ChorusOSMkMf. This path is the same as BSP_DIR: $BUILD_DIR/build-BSP. The DRV_DIST_BIN variable will be used to reference objects exported by the DRV component.

Example 3-5 New BSP: src-level Imakefile

#define IHaveSubdirs

SUBDIRS = boot dbg reboot

This Imakefile lists all of the sub-directories for each BSP class and should not be edited.
