我要评论开端
买到的板子A面长这样
在买之前发现板子上有两个UART 和一个JTAG调试口，全志R16是A33的马甲，看数据手册得知sd卡槽与UART0和JTAG复用这样便使得（比较）无损的从sd卡启动主线linux和uboot成为可能，AC108麦克风矩阵+蓝牙+wifi，果断上车。。。。。
开始挖坑
一番探索后发现PWRON测试点旁边的按钮可以进入sunxi-fel模式，但是是通过SPL而不是直接启动的fel，按照linux-sunxi的说法，这种fel是提取不了nand里的数据的（具体参照）,我们想要的是全志的设备树轮子（script.bin）反编译出fex文件，来写主线内核的设备树。
系统默认的串口是离VBUS比较近的那两个测试点，接上通过内核日志的到分区表
我这台的分区表是这样的
--------fastboot partitions--------
-total partitions:9-
-name- -start- -size-
A env : 1000000 100000
B kernel1 : 1100000 600000
C rootfs1 : 1700000 2000000
D kernel2 : 3700000 600000
E rootfs2 : 3d00000 2000000
F misc : 5d00000 100000
G private : 5e00000 100000
crashlog : 5f00000 100000
UDISK : 6000000 0
-----------------------------------
不难看出小爱同学准备了两套内核和rootfs（squashfs只读文件系统）一个用于最终的使用一个用于生产测试，测试采用的是全志的tinalinux，比较担心的一点是小米有没有把事情做绝，密匙写入cpu，启动任何东西要验证。
然而没有（╮(╯▽╰)╭还没翻车呢） sunxi_secure 为正常模式
root@TinaLinux:/sys/class/sunxi_info# cat sys_info
sunxi_platform : Sun8iw5p1
sunxi_secure : normal
sunxi_chipid : 6c1180001ef65857885c12440461872a
sunxi_chiptype : Not Supported!
sunxi_batchno : 0
按照上一次玩全志平板的经验，script.bin 是放在nand的某一个分区里的，就一个一个去挂nand分区，结果没找到。。。去github搜到了tina旧版的代码，看了下组装固件的过程，发现它是将uboot和设备树文件通过一个c写的小程序拼装在一起，也就是说，只有得到uboot才能够得到设备树。
在sunxi-fel取不出uboot，linux内核也没有可以提取uboot的有效办法，也只好通过小米的ota服务得到。为了得到小米家的升级机制，一个一个把nand分区cat出来，用adb推到电脑，分析ota和boardupdate两个shell文件可以分析出小米大体推送更新的过程。
matool_check_upgrade通过与一个内核模块得到信息返回一个下载固件的地址，miso负责固件的解包，但是miso在更新完后被删除，这时就要在没有adb和有adb的两个系统之间切换，利用唯一可以写入的分区UDISK完成数据的转移。
把miso用adb push到udisk分区，然后切到正常模式，用miso解包出u-boot.fex,在用adb推到电脑，用bless（linux下的16进制编辑器）找到fex的文件头（在ascii对照表大致从PRODUCT字样开始）把fex从里面抠出来，最终成功反编译！
