IMX6Q lvds1 无开机logo显示

清风伴月11

大家好，我使用的是uboot v2015.04，现在换了hannstar 1024x600的TFT屏，改了屏参无显示内容，画面黑屏
屏接的是24bit LVDS1输出，下面是uboot启动日志：

楼主你好，请问你这里使用的是哪块板子？自己设计的开始我们官网的开发板？
你这里使用的是哪个版本的BSP呢？

楼主，你好，你这样使用的屏，driver的移植是否成功，内核启动后屏幕是否可以正常显示？还是什么显示的内容都没有。移植屏的driver的话，屏的参数和驱动要正确。

你这里使用的是24bit LVDS1， 你在uboot中关于LVDS的设置是否是24bit的，你需要查看一下。

在内核中目前就是不能正常显示，uboot和kernel环节都只亮了背光，无其他显示。
按我的理解，即使屏的参数不正确，也会显示花屏什么的吧。
24Bit LVDS1已经设置过了。

kernel运行过程中出现了如下信息：

楼主，你好，请问你帖中问题是否已经解决？

踏月追星

不能显示就检查各路时钟是否有了，楼主解决了也不回来分享。。。
