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

SRCS=$(SRCS:%.o=%.c)

CFLAGS=-g

all: video

.c.o:

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

codec: $(OBJS)
