spi flash启动，按照分区依次烧写BOOT.mcs，uImage，devicetree.dtb，uramdisk.image.gz

然后按照分区修改了uboot的环境变量：setenv qspiboot 'echo Copying Linux from QSPI flash to RAM... && sf probe 0 0 0 && sf read ${kernel_load_address} 0xd00000 ${kernel_size} && sf read ${devicetree_load_address} 0x1200000 ${devicetree_size} && echo Copying ramdisk... && sf read ${ramdisk_load_address} 0x1220000 ${ramdisk_size} && bootm ${kernel_load_address} ${ramdisk_load_address} ${devicetree_load_address}\0'

另外，devicestree.dtb里分区也做了相应修改。

之后上电启动报错：

ERROR: Did not find a cmdline Flattened Device Tree                             

Could not find a valid device tree 

请教各位大大，这是哪里出了问题，怎么解决呢？

非常感谢！
