Before a command is executed, its input and output may be redirected using a special notation interpreted by the shell. Redirection allows commands' file handles to be duplicated, opened, closed, made to refer to different files, and can change the files the command reads from and writes to. Redirection may also be used to modify file handles in the current shell execution environment. The following redirection operators may precede or appear anywhere within a simple command or may follow a command. Redirections are processed in the order they appear, from left to right.
Each redirection that may be preceded by a file descriptor number may instead be preceded by a word of the form{varname} . In this case, for each redirection operator except >&- and <&-, the shell will allocate a file descriptor greater than or equal to 10 and assign it to {varname}. If >&-or<&-is preceded by {varname}, the value of {varname} defines the file descriptor to close.
和亮哥对json的数据类型有了争议，这里直接dump http的post 数据。分析如下post数据的false值。
对比了如上的false值，发现还是一个字符串。

删除安装文件夹的BCUnrar.dll。
DM（显示管理器）功能如下：
不增加其他额外的启动时间；
See <linux/platform_device.h> for the driver model interface to the platform bus: platform_device, and platform_driver. This pseudo-bus is used to connect devices on busses with minimal infrastructure,
like those used to integrate peripherals on many system-on-chip processors, or some "legacy" PC interconnects; as opposed to large formally specified ones like PCI or USB.
Platform devices are devices that typically appear as autonomous entities in the system. This includes legacy port-based devices and host bridges to peripheral buses, and most controllers integrated into system-on-chip platforms. What they usually have in common is direct addressing from a CPU bus. Rarely, a platform_device will be connected through a segment of some other kind of bus; but its registers will still be directly addressable.
...对于NandFlash的认识尝试不做更多理解，只需要了解非易失存储、擦除寿命有限、通常是10K级别，同时写操作需要基于Page来。没有办法按照内存的存储基本单位字节来操作,由多个Page组成一个Block 每个 Page保留 一些字节用以 做ECC （ error correcting code ）校验。
烧写工具HiTool-STB-3.1.35.zip 会在成功编译镜像后自动拷贝到out文件夹。
参考ServerInstall.sh进行初始化环境，主要是包含java 、python、依赖库、gcc安装，然而很多依赖版本过低，所以必须要添加 ubuntu12.04或者14.04源安装。
