摘要 : 修改uboot源码:VS-RK3288板卡HDMI显示uboot和kernel的logo图片

  VS-RK3288板卡HDMI显示uboot和kernel的logo图片

  修改uboot源码:

  include/configs/rk32plat.h

  #define CONFIG_ROCKCHIP_MIPI_DSI

  #define CONFIG_ROCKCHIP_DW_MIPI_DSI

  #define CONFIG_ROCKCHIP_ANALOGIX_DP

  +#define CONFIG_DRM_ROCKCHIP_DW_HDMI

  #define CONFIG_ROCKCHIP_PANEL

  #define CONFIG_I2C_EDID

  #endIF

  修改kernel源码:

  /arch/ARM/boot/dts/rk3288-android.dtsi

  connect = <&vopl_out_edp>;

  };

  + route_hdmi: route-hdmi {

  + status = "disabLED";

  + logo,uboot = "logo.bmp";

  + logo,kernel = "logo_kernel.bmp";

  + logo,mode = "center";

天天乐棋牌  + charge_logo,mode = "center";

  + connect = <&vopb_out_hdmi>;

  + };

  +

  route_dsi0: route-dsi0 {

  status = "disabled";

  logo,uboot = "logo.bmp";

  /arch/arm/boot/dts/rk3288-evb-android-rk808-mipi.dts

  status = "okay";

  };

  +&route_hdmi {

  + status = "okay";

  + connect = <&vopb_out_hdmi>;

  +};

  +

  &gpu {

  status = "okay";

  mali-supply = <&vdd_gpu>;
