Hi, i do this few weeks ago for LVDS display... What i did in u-boot configuration: CONFIG_VIDEO_SUNXI=y # CONFIG_VIDEO_HDMI is not set # CONFIG_VIDEO_VGA is not set # CONFIG_VIDEO_COMPOSITE is not set CONFIG_VIDEO_LCD_MODE="x:1024,y:600,depth:24,pclk_khz:51000,le:319,ri:4,up:34,lo:2,hs:1,vs:1,sync:3,vmode:0" CONFIG_VIDEO_LCD_DCLK_PHASE=1 CONFIG_VIDEO_LCD_POWER="PH9" CONFIG_VIDEO_LCD_RESET="" CONFIG_VIDEO_LCD_BL_EN="PH8" CONFIG_VIDEO_LCD_BL_PWM="" # CONFIG_VIDEO_LCD_BL_PWM_ACTIVE_LOW is not set # CONFIG_VIDEO_LCD_PANEL_I2C is not set CONFIG_VIDEO_LCD_IF_LVDS=y # CONFIG_VIDEO_LCD_PANEL_PARALLEL is not set CONFIG_VIDEO_LCD_PANEL_LVDS=y
You should enable HDMI instead of my LVDS display and set correct times...
