DS90UB960-Q1: Test pattern 在输出1280*720数据时异常。

小其沈

Part Number: DS90UB960-Q1

在实际使用中，我们发现当输出1280*720p_yuv422_8bit@30fps的视频时，DS90UB960-Q1 总是多输出4列数据，总数据量为1284*720。

我们仅使用DS90UB960-Q1 测试模式输出时，发现仍然存在以上问题。

测试模式初始化代码如下：

如代码所示，我配置的测试模式输出为1280*720的yuv4228bit。但是我上位机软件必须要配置为1284*720去解析图像才能得到正确的图像，且图像右侧有明显的一列异常处，如下图所示。

/resized-image/__size/1920x1080/__key/communityserver-discussions-components-files/59/pastedimage1663579889886v1.png

如果我使用1280*720去解析，则得到图像如下图所示：

/resized-image/__size/1920x1080/__key/communityserver-discussions-components-files/59/pastedimage1663579947018v2.png

但是，有趣的是，我将test pattern 输出数据调整为1200x720 的yuv 输出，则并不会存在以上问题。代码改动如下：

您好，

您可以提供所使用显示屏的active 和 blanking 参数吗？也请提供寄存器dump 以方便排查问题

0 小其沈 3 年多前回复 Amy Luo

显示屏？产品在开发阶段，现在是通过USB协议将视频数据上传到PC端显示的，所以跟显示屏没有关系。能确定的是： DS90UB960-Q1 CSI 端口发出的MIPI数据上，确实比预期的1280*720 要多 4*720 的数据量。另外请问寄存器dump 是需要将0x00 -0xff 的寄存器值都读出吗？如果是的话测试模式test pattern 下DS90UB960-Q1 的寄存器值如下：
