DM8147 DVO2 输出 BT1120 数据



大家好:

         目前用的是DM8147+IPNCRDK3.5,想通过DVO2输出BT1120 1080P30帧 数据,遇到以下问题:

         1、DVO2时钟源默认是VENCD,修改DVO2和HDM为I1080P30,时钟没变一直是148.5MHZ,如何得到74.25MHZ时钟?

         2、如果将DVO2时钟源设成VENCD_DIV2,时钟是74.25MHZ,DVO2输出是黑屏,BT1120 16bit数据是一直是1D80

         3、0x4810A000把bit15改成1,也不能输出colorbar
