+### 编译：
+1. 确保交叉编译工具链路径正确
+2. 确保源码放在src目录，头文件放在inc目录
+3. 命令行执行：
+
+   `make        # 编译`
+   `make clean  # 清理`
+
+编译输出文件在build下：`msg_udp_ctrl.out`

+### 交叉编译工具默认路径：
+```angular2html
+TOOLCHAIN_DIR ?= /home/qieyuan/bupt_project/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu

+### msg_udp_ctrl.out
+
+此程序启动一个udp传输，首先会向上位机发送一个 `reday`  ，上位机收到后，向客户端发送一个 `OK` (GUI界面中是以按钮的形式点击)，然后客户端就会将一个固定值写入 `DDR 0x82000000` 中，用来启动 UCP4008 和 RK3588 的后续任务。
