Getting VGA to work on Arrow SoCKit

Hi SOCRY, I'm newbie

I am trying to create Test Pattern Gen -> CVO, then display to VGA port on sockit board. I connected

vga_clocked_video_vid_clk(clk_25), // vga_clocked_video.vid_clk

vga_clocked_video_vid_data(rgb_data), // .vid_data

vga_clocked_video_underflow(), // .underflow

vga_clocked_video_vid_datavalid(vid_datavalid), // .vid_datavalid

vga_clocked_video_vid_v_sync(v_sync), // .vid_v_sync

vga_clocked_video_vid_h_sync(h_sync), // .vid_h_sync

vga_clocked_video_vid_f(), // .vid_f

vga_clocked_video_vid_h(), // .vid_h

vga_clocked_video_vid_v()

Then assigned it to VGA pins

assign VGA_SYNC_n = 1'b1;

assign VGA_R = rgb_data[23:16];

assign VGA_G = rgb_data[15:8];

assign VGA_B = rgb_data[7:0];

assign VGA_BLANK_n = vid_datavalid;

assign VGA_CLK = !clk_25;

assign VGA_HS = !h_sync;

assign VGA_VS = !v_sync;

But it still didnt work. Can you tell me where I should reconnect?

I would appreciate your help!!
