Hello sir,

I have write the simple C program for led blink for BF 561 EZ-KIT.As I read from documentation, first I am compiling the code through bfin-elf-gcc. When in code main function named as a int coreb_main(void) then I am getting following error

[root@PranayU coreb_ledblink]# make

bfin-elf-gcc -o blink -mcpu=bf561-0.3 -mmulticore -mcoreb main_c.o

/opt/uClinux/bfin-elf/lib/gcc/bfin-elf/4.1.2/../../../../bfin-elf/lib/bf561-0.2/basiccrt.o: In function `__start':

/usr/src/packages/BUILD/blackfin-toolchain-08r1/../gcc-4.1/libgloss/bfin/basiccrt.S:390: undefined reference to `_main'

collect2: ld returned 1 exit status

make: *** [blink] Error 1

But the main function is simple int main(void), then there is no error and compiled successfully.Is it formed elf file is write?

And when I run the made elf file in coreB using the given command

/pranay/uClinux-dist/user/blkfin-apps/corebld/coreb> corebld main_c

Then I am getting error like that

bash: /pranay/uClinux-dist/user/blkfin-apps/corebld/coreb: cannot execute binary file

where am I doing wrong please, guide me?

-Regards

Pranay

Why not define main() in your program?

Hello sir,

I have read in some document that when code used for the coreB you give main function as a coreb_main.Now I am using as main(). I am reading the document for loading the C program to the Core B.I am trying to do same thing but I am not successful.I have loaded the 2008R1 uboot. Can you told me some more document about this.Where is the coreb driver, for loading the c-program in core B?

When I am booting that code then I am getting following error
