VIP suite frame reader

hello.

I'm trying to use Video Image Processing suite.

I could out test pattern with Test Pattern Generator.

after that, I'm trying to use frame reader.

SOPC builder is like attached.

also NiosII source is like below.

//--------------------------------------- NiosII --------------------------------------------

# include <stdio.h>

# include <io.h>

# include "system.h"

# include <malloc.h>

# define ADDRMULT 1

# define CONTROL (0 * ADDRMULT)

# define STATUS (1 * ADDRMULT)

# define INTERRUPT (2 * ADDRMULT)

# define FRAMESEL (3 * ADDRMULT)

# define FRAME0BADD (4 * ADDRMULT)

# define FRAME0HIGT (9 * ADDRMULT)

# define FRAME0INTR (10* ADDRMULT)

# define BASEWIDTH 640

# define BASEHEIGHT 480

# define COLORNUM 3

int main()

{

unsigned char* fbuf0;

long loop;

fbuf0 = (unsigned char*)malloc(BASEWIDTH*BASEHEIGHT*COLORNUM);

IOWR(ALT_VIP_VFR_0_BASE,CONTROL,0x00);

usleep(100000);

IOWR(ALT_VIP_VFR_0_BASE,FRAME0BADD,(int)fbuf0);

IOWR(ALT_VIP_VFR_0_BASE,FRAMESEL,0x00);

IOWR(ALT_VIP_VFR_0_BASE,FRAME0WIDT,BASEWIDTH);

IOWR(ALT_VIP_VFR_0_BASE,FRAME0HIGT,BASEHEIGHT);

IOWR(ALT_VIP_VFR_0_BASE,FRAME0WORD,4);

IOWR(ALT_VIP_VFR_0_BASE,CONTROL,0x01);

for( loop = 240*640*3; loop < 250*640*3;loop++)

{

fbuf0[loop] = 0; // test pattern

}

return 0;

}

//------------------------------------ NiosII -------------------------------------------------

when I see signals Avalon Master is not read from the sdram( it looks like stuck )

what should I miss? what should I try?
