Sprite rendering failure in GBA

I tried the code from TONC example for GBA development, specifically the obj_demo example. It loads the sprite located in the array at the metr.h, based on this image. These are codes in metr.h and metr.c:

And this is the main code to load the sprite from metr.c.

    #include <tonc.h>
    #include <string.h>
    #include "metr.h"

    OBJ_ATTR    obj_buffer[128];
    OBJ_AFFINE  *obj_aff_buffer = (OBJ_AFFINE*)obj_buffer;


    int main()
    {
        /* copy array of tiles to tile_mem */
       memcpy( &tile_mem[4][0], metrTiles, metrTilesLen );
       /* copy array of pallete to pallet object memory */
       memcpy( pal_obj_mem, metrPal, metrPalLen);

    /* malloc()-ing the obj_buffer according to its length */
    oam_init( obj_buffer, 128 );
    REG_DISPCNT = DCNT_MODE0 | DCNT_OBJ | DCNT_OBJ_1D;

    u16 x       = 96;
    u16 y       = 32;
    u32 tid     = 0;
    u32 palbank = 0;

    OBJ_ATTR    *metr = &obj_buffer[0];
    obj_set_attr( metr,
                  ATTR0_SQUARE,
                  ATTR1_SIZE_64,
                  ATTR2_PALBANK(palbank) | tid );


    obj_set_pos( metr, x, y );

    while(1)
    {
        vid_vsync();
        key_poll();

        oam_copy( oam_mem, obj_buffer, 1 );
    }

    return 0;
}

It works well, so I tried to create my own sprite code based on this image. Here's the resulting sprite array in .h and .c file:

And I modify the code based on the main code I showed before.

#include <tonc.h>
#include <string.h>
#include "knight.h"

OBJ_ATTR    obj_buffer[128];
OBJ_AFFINE  *obj_aff_buffer = (OBJ_AFFINE*)obj_buffer;


int main()
{
    /* copy array of tiles to tile_mem */
    memcpy( &tile_mem[4][0], knight, KNIGHT_LENGTH );
    /* copy array of pallete to pallet object memory */
    memcpy( pal_obj_mem, knight_palette, KNIGHT_PALETTE_LENGTH);

    /* malloc()-ing the obj_buffer according to its length */
    oam_init( obj_buffer, 128 );
    REG_DISPCNT = DCNT_MODE0 | DCNT_OBJ | DCNT_OBJ_1D;

    u16 x       = 96;
    u16 y       = 32;
    u32 tid     = 0;
    u32 palbank = 0;

    OBJ_ATTR    *metr = &obj_buffer[0];
    obj_set_attr( metr,
                  ATTR0_TALL,
                  ATTR1_SIZE_64,
                  ATTR2_PALBANK( 0 ) | KNIGHT_ID );



    obj_set_pos( metr, x, y );

    while(1)
    {
        vid_vsync();
        key_poll();

        oam_copy( oam_mem, obj_buffer, 1 );
    }

    return 0;
}

When I compiled it, it just only showing the broken pixel, as shown in here. Any idea why the rendering is not working as I expected while I just changed the content of the array?
