上面是打印log，
update_kern 命令对应自动网络下载并烧录内核文件 image_file=zImage-myimx6
update_fdt 命令对应自动网络下载并烧录设备树文件 fdt_file=myimx6ek314-6q.dtb
对吧？
fdt_file=myimx6ek314-6q.dtb
fdt_addr=0x18000000 ---------------这个是设备树的烧录起始地址
fdt_high=0xffffffff
image_file=zImage-myimx6
initrd_addr=0x12C00000
initrd_high=0xffffffff
loadaddr=0x12000000 --------这个是内核的烧录起始地址吧？
initrd_addr=0x12C00000 ---这个地址是什么内容？
另外没找到文件系统的烧录起始地址，是initrd_addr 吗？
有文件系统的自动更新命令吗？ |
