imx6ul-14x14-evk-emmc-c-7-1024x600 无法启动

最近在淘宝上的开发板，使用SD卡（USB接口转换过的）更新了板子内的imx6ul-14x14-evk-emmc-c-7-1024x600.dtb（文件是通过淘宝卖家提供的百度网盘下载的原件）文件后，重启时选择这个文件，logo正常显示（说明分辨率是正确的），但是无法启动，显示信息如下：

目前板子内的dtb文件如下：

显示屏是1024*600的选择6不行，选择其他分辨率logo及后续的显示不正确，但是这个系统可以启动成功。
请问是什么原因？

要命的是我把板子内的原件给删了、删了、删了......

全部更新一下系统吧，可能是你用的资料比较久，设备树名称不匹配，更新一下最新的资料试一下
