SN65DSI86-Q1: 彩条输出Color Bar

需要将此单元格切换为"是"。 到目前为止、该脚本未反映提供的输入：

您将需要在 DSI86的输出端进行交流耦合。 能否发送完整的原理图？

2周前DP已经输出正常的color bar。通过树莓派(CM4004016)的DSI输出1920*1200的图像后（DSI的CLK=500MHZ），DP没有图显示。

您好！

您能告诉我们在这种情况下是如何使用500 MHz DSI 时钟的吗？ 此外、您能否共享您现在拥有的计算器工具设置、以及检查初始化脚本中的 DSI 设置是否与 Raspberry Pi 的设置相匹配？ 由于这显示了 PLL 解锁、因此这很可能是由于 DSI 配置不匹配造成的。 此外、TEST2引脚是否有上拉电阻器？
