1. 生成 sunxi_mbr.fex

需要生成如下1~5这些文件才可以生成 sunxi_mbr.fex 和 dlinfo.fex

// 生成 sunxi_mbr.fex 和 dlinfo.fex
$ update_mbr sys_partition.bin 4

(1) 生成 sys_partition.bin

$ busybox unix2dos sys_partition.fex
$ script sys_partition.fex

(2) 生成 boot-resource.fex

$ fsbuild boot-resource.ini split_xxxx.fex 	// 注意boot-resource.ini文件里面的斜杠方向，可能根据windows或linux平台需要修改调整

(3) 生成env.fex

$ u_boot_env_gen env.cfg env.fex

(4) 生成boot.fex

// linux 编译过程
$ cp -vf  arch/arm/boot/Image output/bImage
$ mkbootimg 
					--kernel output/bImage 
					--ramdisk output/rootfs.cpio.gz 
					--board sun8i_arm 
					--base 0x40000000 
					--kernel_offset 0x8000 
					--ramdisk_offset 0x01000000 
					-o output/boot.img
$ ln -sf boot.img        boot.fex

(5) 生成rootfs.fex

$ ln -sf rootfs.ext4     rootfs.fex

不废话了，来个Makefile文件吧

2. 烧录 sunxi_mbr.fex

将 sunxi_mbr.fex 烧录 到 第 40960 sector位置

$ sudo dd if=./sunxi_mbr.fex of=/dev/sdb bs=512 seek=40960 && sync

3. 烧录 boot.fex (内核)

确定boot.fex的烧录位置：

这里从 sunxi_mbr.fex 里面可以找到boot分区的起始sector是 00 00 D8 00 即：55296，实际的烧录位置需要在55296基础上再加上 sunxi_mbr.fex的偏移，即实际的烧录位置是：55296+40960=96256

$ sudo dd if=./boot.fex of=/dev/sdb bs=512 seek=96256 && sync
