2.若用户未曾手动设置过分辨率,且开机HDMI成功读取EDID,则选用EDID中的与 rockchip,defaultmode的值对应的分辨率。 3.若EDID中不存在rockchip,defaultmode对应的分辨率,则选择EDID中最大的分辨率。 4.若读取EDID失败,则直接使用rockchip,defaultmode对应的分辨率。
1. 当HPD为高时,AD9889读取EDID程序段0,向系统发送 EDID Ready中断。一旦成功读取EDID,即设置EDID Ready标志(0xC54)。2. 18、当读 EDID 时,AD9889 等待 HDCP Desired 位(0xAF7)变为高电平。3. 系统软件评估EDID,通过设置适当的视频和音频模式来配置AD9889,然后设置HDCP Desired位为高电平(该位的状态也在...
