楼主你好，你能把终端上打印的信息发给我看一下吗？

上面是终端的打印信息，我用的是要烧录的内核，红色的部分是我在终端停止打印之后输入的。

楼主你好，请问你这里是要写到哪个flash上的呢？还有你的设计中电源模块你使用哪个，如何设计的？

你可以根据串口上打印的信息看是哪里存在的问题。

我也有注意那句打印信息，我用的是mc34708，这句打印是在board_late_init（）里面读写i2c失败打印的，但是我问过硬件工程师电源管理芯片上电就会跑起来不用我去管。我在看看这一块

电源模块设置不正确也会出现上述问题的。

我现在可以跑到内核了，查看mfgtool.log也进入了写命令阶段，但是进入写命令烧写就失败了。

<CMD type="push" body="mknod class/mtd,mtd1,/dev/mtd1"/>

<CMD type="push" body="$ echo Update Complete!">Done</CMD>

上面的是ucl.xml文件的烧写段，日子如下：
1 - Panel A Finished <CMD/> type="jump" body="" file="" timeout="10" onError="" text=" Jumping to OS image. " SUCCESS code=0x0.

Panel A Start <CMD/> type="find" body="Updater" file="" timeout="180" onError="" text="".

Panel A: Command is not supported by device.,failed to run command: type="push" body="mknod class/mtd,mtd0,/dev/mtd0" file="" timeout="10" onError="" text=""

2 - Panel A Finished processing MX53-Loco <LIST/> : FAIL code=-22.

Panel A: Reason is unknown,

请问我的mknod 阶段的命令有错误吗？

好像是mknod执行失败了
