        试试修改下厂家给的initcode，之前遇到过这样的，但是没这么严格

          @YuzukiTsuru 谢谢大佬，请问这个是厂家给的初始化代码问题是吗？和soc方面有关系吗？因为改 了相关的参数，将像素时钟反相过也没得到改善，更改了RGB寄存器的输出方式也没得到改善，不知道问题出在哪，麻烦大佬能进一步指点一下吗🤝

            @fans168168 之前我调试过这款屏幕，initcode的问题，尽量不要从soc驱动修改，扩大问题

              @yuzukitsuru 好的，谢谢，您还有这款屏的初始化代码吗？问了屏厂家，说他们的初始化没问题，让我找soc提供帮助😧

                  @fans168168 个人拙见，应该是rgb色位问题。

                    @tevet 大佬，是不是控制器的数据线和驱动芯片的数据线没对上，下面是原理图，是不是连接有问题

                        //PCLK 30MHZ

                        示波器量一下 PCLK 是不是 30M ?

                            再看下 DE/VSYNC/HSYNC 频率是否正常，像素点抖不抖？

                              @fans168168 可以检查下RGB各颜色pin脚是否有复用，导致RGB有些脚没有输出

                                @whycan 屏有点抖，RGB都是混的，感觉是RGB都错位了一样，因为soc默认输出是24bit,屏是18bit

                                    @fans168168 这个方法不错， 一个一个脚用示波器看下，如果没有信号，可能是被别的功能占用了。

                                                查查是不是rgb的针脚接的顺序不对？还有rgb的高低电平是不是反了？看看屏幕手册，感觉图像能看到说明数据是有了，颜色不对
