FILE LIST - buffSend.c buffReceive.c DESCRIPTION - The following code example uses memory from the shared memory system partition to share data between tasks on different CPUs. The first member of the data structure is a shared semaphore that is used for mutual exclusion. The send task creates and initializes the structure. The receive task simply accesses the data and displays it. RUNNING DEMO - Place the buffSend.c and buffReceive.c in your dir. Depending on the target you have, define the CPU in your compile line and use the Makefile in the BSP dir. to compile. Add INCLUDE_SM_NET , INCLUDE_SM_SEQ_ADDR and INCLUDE_SM_OBJ in the config.h file in the BSP Install VxMP into your Tornado tree before running this code. Re-make vxWorks and reboot your system. The file buffSend.c writes to the shared memory. The function buffSend() writes to the shared semaphore protected buffer. The file buffReceive.c reads the shared memory. The function buffReceive() receives shared semaphore protected buffer. TESTED ON - Host/Target : Solaris 2.5.1 / mv1604 VxWorks : 5.3.1 EXAMPLE COMPILE LINE - make CPU=PPC604 buffSend.o make CPU=PPC604 buffReceive.o % make buffSend.o ccppc -B/petaluma1/mayur/tor101-ppc/host/sun4-solaris2/lib/gcc-lib/ -mstrict-align -ansi -nostdinc -O2 -fvolatile -fno-builtin -fno-for-scope -Wall -I/h -I. -I/petaluma1/mayur/tor101-ppc/target/config/all -I/petaluma1/mayur/tor101-ppc/target/h -I/petaluma1/mayur/tor101-ppc/target/src/config -I/petaluma1/mayur/tor101-ppc/target/src/drv -DCPU=PPC604 -DMV1600 -DTARGET_DIR="\"mv1604\"" -c buffSend.c % make buffReceive.o ccppc -B/petaluma1/mayur/tor101-ppc/host/sun4-solaris2/lib/gcc-lib/ -mstrict-align -ansi -nostdinc -O2 -fvolatile -fno-builtin -fno-for-scope -Wall -I/h -I. -I/petaluma1/mayur/tor101-ppc/target/config/all -I/petaluma1/mayur/tor101-ppc/target/h -I/petaluma1/mayur/tor101-ppc/target/src/config -I/petaluma1/mayur/tor101-ppc/target/src/drv -DCPU=PPC604 -DMV1600 -DTARGET_DIR="\"mv1604\"" -c buffReceive.c OUTPUTS/LOGFILE - On VxWorks target: ================== -> ld ld
