+# 瑞萨 EK-RA4M1 开发板 BSP 说明
+
+## 简介
+
+本文档为瑞萨 EK-RA4M1 开发板提供的 BSP (板级支持包) 说明。通过阅读快速上手章节开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。
+
+主要内容如下：
+
+- 开发板介绍
+- BSP 快速上手指南
+
+## 开发板介绍
+
+基于瑞萨 RA4M1 MCU 开发的 EK-RA4M1 MCU 评估板，通过灵活配置软件包和 IDE，可帮助用户对 RA4M1 MCU 群组的特性轻松进行评估，并对嵌入系统应用程序进行开发。
+
+开发板正面外观如下图：
+
+![](docs/picture/ek-ra4m1-board-front.png)
+
+该开发板常用 **板载资源** 如下：
+
+- MCU：R7FA4M1AB3CFP，48MHz，Arm Cortex®-M4 内核，256KB 代码闪存, 32KB SRAM
+- 调试接口：板载 J-Link 接口
+- 扩展接口：Arduino Uno 兼容接口
+
+**更多详细资料及工具**
+
+## 外设支持
+
+本 BSP 目前对外设的支持情况如下：
+
+| **片上外设** | **支持情况** | **备注** |
+| :----------------- | :----------------- | :------------- |
+| UART               | 支持               | SCI0 为默认日志输出端口 |
+| GPIO               | 支持               |                |
+| IIC                | 支持               | 软件           |
+| WDT                | 支持               |                |
+| RTC                | 支持               |                |
+| ADC                | 支持               |                |
+| DAC                | 支持               |                |
+| SPI                | 支持               |                |
+| FLASH              | 支持               |                |
+| PWM                | 支持               |                |
+
+## 快速上手
+
+本 BSP 目前支持GCC和MDK工程，开发前请使用 USB 数据线连接开发板到 PC，使用 J-link 接口下载和 DEBUG 程序。使用 USB 转串口工具连接 SCI0：P410(TXD)、P411(RXD)。
+
+### 编译
+
+#### MDK
+
+MDK工程步骤如下：
+
+1. 在 bsp 下打开 env 工具。
+2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
+3. 输入`pkgs --update`命令更新软件包。
+4. 输入`scons --target=mdk5` 命令重新生成工程。
+
+#### GCC
+
+GCC工程步骤如下：
+
+1. 在 bsp 下打开 env 工具。
+2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
+3. 输入`pkgs --update`命令更新软件包。
+4. 输入`scons` 命令即可编译工程。
+
+### 烧录
+
+打开 J-Flash lite 工具，选择芯片型号 R7FA4M1AB，点击 OK 进入工具。选择 BSP 目录下 编译出的 rtthread.hex 文件，点击 Program Device 按钮开始烧录。具体操作过程可参考下图步骤：
