+# GD32450Z-EVAL
+
+## 简介
+
+GD32450Z-EVAL是-兆易创新推出的一款GD32F450系列的评估板，板载资源主要如下：
+
+| 硬件      | 描述          |
+| --------- | ------------- |
+| 芯片型号  | GD32F450ZKT6  |
+| CPU       | ARM Cortex M4 |
+| 主频      | 200M          |
+| 片内SRAM  | 256K          |
+| 片外SDRAM | 32M           |
+| 片内FLASH | 3072K         |
+
+## 编译说明
+
+GD32450Z-EVAL板级包支持MDK4﹑MDK5﹑IAR开发环境和GCC编译器，以下是具体版本信息：
+
+| IDE/编译器 | 已测试版本                   |
+| ---------- | ---------------------------- |
+| MDK4       | MDK4.74                      |
+| MDK5       | MDK524a                      |
+| IAR        | IAR 7.60~IAR8.20             |
+| GCC        | GCC 5.4.1 20160919 (release) |
+
+## 烧写及执行
+
+供电方式：开发板使用 Mini USB 接口或者 DC-005 连接器提供 5V 电源。
+
+下载程序：下载程序到开发板需要一套 JLink 或者使用 GD-Link 工具。
+
+串口连接：使用串口线连接到COM1(UART0)，或者使用USB转TTL模块连接PA9(MCU TX)和PA10(MCU RX)。
+
+### 运行结果
+
+如果编译 & 烧写无误，当复位设备后，会在串口上看到RT-Thread的启动logo信息：
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     3.0.4 build May 22 2018
+ 2006 - 2018 Copyright by rt-thread team
+finsh />
+
+```
+## 驱动支持情况及计划
