am335x自制板 显示屏显示“”please wait“”

大家好，我使用ti-sdk移植u-boot及linux到自制板上，开机后u-boot能启动，在串口能操作显示sd卡内的数据，但显示屏显示的是黑色背景加一行白字“”please wait“”，无其他内容。

请问这是怎么一回事，该如何解决.

我按照网上说的输入一些命令，屏幕均不能显示，具体命令如下

请问您的代码在EVM板上也有这个问题吗? SDK是最新的版本么？

,

ZB_LAJI：

这个并没有在EVM板上进行尝试，SDK为ti-processor-sdk-linux-am335x-evm-06.03.00.106。

Shine：

能否发一下kernel启动的log？
另外，看一下是否按照下面的网站配置的？

里面似乎是说非32倍数的配置，我的LCD是32的倍数。log如下：

里面似乎是说非32倍数的配置，我的LCD是32的倍数。log如下：

AM335x LCD controller只支持24bit data，能否详细描述一下您板子LCD那块的硬件和配置信息？执行一下lsmod命令，并把输出信息贴出来看一下。

,

ZB_LAJI：

配置为修改evmsk中的参数，且只使用0-15作为RGB输出。

但开机显示仍为please wait 。

Shine：

请问在设置上面这些参数有reboot板子吗？运行一下kmscube test，然后把output贴出来看一下。

,

ZB_LAJI：

output显示如下：

Shine：

虽然是16bit LCD，但DTS entry需要设成 bpp=32，请确认一下这个配置。

,

ZB_LAJI：

确认了一下，bpp是32

Shine：

请问您是怎么build rootfs的？在设备树里是否有使能GPU? GPU driver是如何编译的？

,

ZB_LAJI：

我使用的是sdk里面自带的tisdk-rootfs-image-am335x-evm.tar.gz，

另外·，在我使用arago-base-tisdk-image-am335x-evm作为跟文件系统时，显示屏只显示类似以下图片，之后就不动了。

,

ZB_LAJI：

另外，我想请问一下设备树使能GPU是怎么实现。

,

Shine：

您使用的是旧版的filesystem，请使用PSDK6.3里的filesystem文件
software-dl.ti.com/…/index_FDS.html

,

ZB_LAJI：

我所使用的是最新版文件系统2019，因无法拍照图片是网上找到相近的。

,

ZB_LAJI：

你好，我们将板子进行了修改，采用了24位的10.1寸LVDS屏幕，并将设备树中管脚与display-timings改为了新屏幕的，但仍旧显示为please wait。

此外当选择输出一张图片时，图片显示是错乱的 ：应该为一个logo却显示为两个且模糊有重影 

请问是否还有其他需要修改的？
