** Unable to read file zImage-imx6ull-14x14-evk-emmc.dtb **问题

yiyizhao

想尽一切方法终于把文件烧到EMMC了，但是还有到了Starting kernel ...死在那里了，把认为是重点错误的用红色显示了，奇怪的是不知为什么zImage-imx6ull-14x14-evk-emmc.dtb文件读不到。帮忙看看什么原因

uboot输入命令ls mmc 1:1，看看内容

z2500abc

这个你要看下 uboot中设置的bootcmd 变量里面 设置的设备树的名字 是不是zImage-imx6ull-14x14-evk-emmc.dtb

你是烧写NXP的固件？请检查mfgtool工具的自带镜像文件是否存在该设备树文件。未解决问题请留言。

环境变量是指fdt_file吗？如果是应该是对的

=> print fdt_file
fdt_file=zImage-imx6ull-14x14-evk-emmc.dtb

uboot输入命令ls mmc 1:1，看看内容

=> ls mmc 1:1
  6788760   zimage
    38823   imx6ull-14x14-evk.dtb

2 file(s), 0 dir(s)

谢谢！ 才发现文件名错了，能在uboot下改名吗？

yiyizhao

补充以下，问题解决了，文件名不是zImage-imx6ull-14x14-evk-emmc.dtb，居然不是mfgtools的files下面的文件名。修改了uboot-->board-->freescale-->mx6ullevk.c 下的文件名，问题解决

uboot123456

请问一下这个报错怎么解决

还有就是为啥我的ls mmc 1:1 下有这么多的文件 我不知道那些是没用的我想删除
