2008-07-29 06:56:53     stand application using dual core

Hello sir,


           I have tested the standalone application in single core for audio application from bfin-elf-gcc compiler and it is working correctly on BF 561Ez-kit after loading the elf file using u-boot.I had loaded and compile the recently used u-boot2008 version that support BF 561.


      Now I am using the core A and core B as used in the VDSP program. Is it posiible now that we can use both core at a time one core for video in and other core for the video out as used by the VDSP program? I have write the code for that type of application .The function which is used by coreb i have written lik this


void InitInterrupts_coreB(void) __attribute__ ((section (".b.text")));

void InitInterrupts_coreB(void)


But when we compile the program using  bfin-elf-gcc the isr function which used in the coreb , giving error that


No rule to make target 'isrb.o', needed by video ,stop.


I have written the MAKEFILE like this



OBJS= isra.o main.o I2C.o  isrb.o coreb.o




all: video



bfin-elf-gcc -c -mcpu=bf561 $(CFLAGS) $< -o $@


codec: $(OBJS)

bfin-elf-gcc -o $@ -mcpu=bf561 -mmulticore $(OBJS)



rm -f video *.o *.i *.s



Is it possible to use core A and core B for using the video in-out apllication as used by the VDSP code.
