Does STM32F469I DISCO-AU1 have a example to work in TOUCHGFX with VIDEO MODE?

   Hi,I'am a beginner of STM32F469 DISCO-AU1.

  In the Next week,I will use STM32F469 to light up a external screen. This external screen's driver IC is GC9503CV.It can only work in video mode(In my opinion).

  In order to do early prepare,So I am trying to let STM32F469I DISCO-AU1 work in video mode,use TOUCHGFX tool,but I failed.

  I have view a lot about F469 vedio mode,download and rewrite and try for 1 month ,but finally failed.

  Does now have a STM32F469 DISCO-AU1&TOUCHGFX&Video mode example？

  I upload two project ,one is video mode failed project named "M1-H800"，one is cmd mode succeeful project named "M1-H800-OK"

  I want to know the key error of my DSI video mode setting.  Thanks a lot.

  This is now a part setting of MX_DSIHOST_DSI_Init:

VidCfg.VirtualChannelID = 0;

VidCfg.ColorCoding = DSI_RGB565;

VidCfg.LooselyPacked = DSI_LOOSELY_PACKED_DISABLE;

VidCfg.Mode = DSI_VID_MODE_BURST;

VidCfg.PacketSize = 800;

VidCfg.NumberOfChunks = 0;

VidCfg.NullPacketSize = 0xfff; //0XFFF

VidCfg.HSPolarity = DSI_HSYNC_ACTIVE_HIGH;

VidCfg.VSPolarity = DSI_VSYNC_ACTIVE_HIGH;

VidCfg.DEPolarity = DSI_DATA_ENABLE_ACTIVE_HIGH;

VidCfg.HorizontalSyncActive = 4;

VidCfg.HorizontalBackPorch = 77; //71

VidCfg.HorizontalLine = 1977; //1813

VidCfg.VerticalSyncActive = 1; //1

VidCfg.VerticalBackPorch = 15; //16

VidCfg.VerticalFrontPorch = 16; //15

VidCfg.VerticalActive = 480;

VidCfg.LPCommandEnable = DSI_LP_COMMAND_ENABLE;

VidCfg.LPLargestPacketSize = 0;

VidCfg.LPVACTLargestPacketSize = 16;

VidCfg.LPHorizontalFrontPorchEnable = DSI_LP_HFP_ENABLE;

VidCfg.LPHorizontalBackPorchEnable = DSI_LP_HBP_ENABLE;

VidCfg.LPVerticalActiveEnable = DSI_LP_VACT_ENABLE;

VidCfg.LPVerticalFrontPorchEnable = DSI_LP_VFP_ENABLE;

VidCfg.LPVerticalBackPorchEnable = DSI_LP_VBP_ENABLE;

VidCfg.LPVerticalSyncActiveEnable = DSI_LP_VSYNC_ENABLE;

VidCfg.FrameBTAAcknowledgeEnable = DSI_FBTAA_DISABLE;

if (HAL_DSI_ConfigVideoMode(&hdsi, &VidCfg) != HAL_OK)

{

Error_Handler();

}

if (HAL_DSI_SetGenericVCID(&hdsi, 0) != HAL_OK)

{

Error_Handler();

}
