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
