+# 编译Windows版本
+
+## 1.安装msys2
+
+到[msys2官网](https://www.msys2.org/)下载安装最新的64位版本，安装完成后打开mingw-32bit窗口，执行以下命令安装依赖：
+
+`pacman -S autoconf automake pkg-config libtool binutils gcc git make mingw-w64-i686-toolchain mingw-w64-i686-libusb mingw-w64-i686-hidapi mingw-w64-i686-libftdi`
+
+## 2.下载源码
+
+下载本项目的所有代码到msys2的某个目录下：
+
+`git clone --recursive https://gitee.com/liangkangnan/tinyriscv-openocd.git`
+
+## 3.编译源码
+
+### 3.1第一次编译或者重新编译
+
+在项目的根目录下，执行以下命令：
+
+`./rebuild.sh`
+
+### 3.2打包openocd.exe
+
+编译完成后就可以打包了，执行以下命令进行打包：
+
+`./release.sh`
+
+打包后的文件在根目录下的release目录里，可以把整个release目录拷贝到电脑的其他目录下使用。
+
+### 3.3修改源码后编译
+
+修改源码后，只需要执行make命令即可编译。
+
+`make`
+
+编译完可以按照步骤3.2进行打包。
+
+# 编译Linux版本
+
+以ubuntu系统为例。
+
+## 1.安装依赖
+
+`sudo apt-get install autoconf automake pkg-config libtool libusb-dev libusb-1.0-0-dev libhidapi-dev`
+
+## 2.编译
+
+```
+./bootstrap
+./configure --enable-remote-bitbang --enable-cmsis-dap --enable-ftdi
+make
+```
+
+编译完成后会在src/目录下生成openocd可执行文件。

+Compute the 32-bit CRC of @var{buf} which has length @var{len}.  The
+starting value is 0xffffffff.
+This is used by the @command{gdb} remote protocol for the @samp{qCRC}
+command.
+This CRC can be specified as:
+  Width  : 32
+  Poly   : 0x04c11db7
+  Init   : 0xffffffff
+  RefIn  : false
+  RefOut : false
+  XorOut : 0
+This differs from the "standard" CRC-32 algorithm in that the values
+are not reflected, and there is no final XOR value.  These differences
+make it easy to compose the values of multiple blocks.
