问答对人有帮助，内容完整，我也想知道答案 0 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： Copyright (C) 2006-2016 Forlinx Embedded Technology Co., Ltd All Rights Reserved www.forlinx.com freescale login: [ 10.087584] <<-GTP-INFO->> System resume.
