分步式编译无法进入linux，需要输入uboot指令。

根据之前大佬的建议，我尝试将zImage改成了Image，并且修改了boot.scr。但仍旧不行，后来在启动时，进入uboot命令窗口，我输入了如下四条指令：

1. 1. u-boot> fatload mmc 0 0x00200000 zImage
   
2. 2. u-boot> fatload mmc 0 0x00100000 system.dtb
   
3. 3. u-boot> fatload mmc 0 0x04000000 rootfs.cpio.gz.u-boot
   
4. 4. u-boot> bootz 0x00200000 0x04000000 0x00100000

复制代码

起初执行到第三步时，没有读取成功，于是我将rootfs.cpio.gz.u-boot也放入了FAT分区。
然后重新执行了，顺利进入了系统。我是根据领航v3教程操作的，教程中并未将该文件放入FAT分区。
请问该用什么办法直接上电自动进入，而不是输入uboot命令后才能进入？能力有限，并未深入了解这些东西，仅是复现。

先用资料盘里的启动文件试试，不行的话可能是环境变量的问题，需要把flash格式化

不知道是不是开发板不一样。我选的是和自己一样的7010的zyqn_petalinux中的linux_driver_boot中的文件，然后拷贝到SD卡直接启动不了了。

我把SD卡重新制作了一下，还是不行。
