拷贝如下文件到C:\Users\greene\Desktop\USB_fastboot_tool\platform-tools
路径
- ramdisk-uboot.img
- system.img
- u-boot-iTOP-4412.bin
- zImage
进入uboot命令行
分区:fdisk -c 0
格式化:
fatformat mmc 0:1
ext3format mmc 0:2
ext3format mmc 0:3
ext3format mmc 0:4
执行fastboot,连接otg,检查adb设备是否生效
管理员方式启动cmd,进入到C:\Users\greene\Desktop\USB_fastboot_tool\platform-tools路径下
烧写bootloader:
fastboot.exe flash bootloader u-boot-iTOP-4412.bin
烧写内核:
fastboot.exe flash kernel zImage
烧写ramdisk:
fastboot.exe flash ramdisk ramdisk-uboot.img
烧写文件系统:
fastboot.exe flash system system.img
格式化用户空间:
