+# HRSDK-GDB-ES8P508 开发板 BSP 说明
+标签： EastSoft、国产MCU、Cortex-M0、ES8P5088FLLQ
+
+## 1. 简介
+
+本文档为上海东软载波微电子开发团队为 HRSDK-GDB-ES8P508 开发板提供的 BSP (板级支持包) 说明。
+通过阅读本文档，开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。
+
+### 1.1  开发板介绍
+
+主要内容如下：
+HRSDK-GDB-ES8P508x 是东软载波微电子官方推出的一款基于 ARM Cortex-M0 内核的开发板，最高主频为 48MHz，可满足基础功能测试及高端功能扩展等开发需求。
+
+开发板外观如下图所示：
+
+HRSDK-GDB-ES8P508x-V1.0
+
+![ES8P508](figures/HRSDK-GDB-ES8P508x-V1.0.jpg)
+
+该开发板常用 **板载资源** 如下：
+
+- MCU：ES8P5088FLLQ，主频 48MHz，24KB SRAM，128KB FLASH，45 GPIOs
+- 常用外设
+  - LED：1个，(PA14)
+  - 按键：1个(MRSTN)
+- 常用接口：GPIO、UART、SPI、I2C
+- 调试接口，ESLinkⅡ(EastSoft 官方推出的开发工具，有标准版和mini版两种版本，均自带 CDC 串口功能) SWD 下载
+
+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**                            |
+| :---------------- | :----------: | :-----------------------------------|
+| GPIO              |     支持     | 45 GPIOs                            |
+| UART              |     支持     | UART0/1/2/3/4/5                     |
+
+
+更多详细信息请咨询[上海东软载波微电子技术支持](http://www.essemi.com/)
+
+## 2. 快速上手
+
+本 BSP 为开发者提供 MDK4 工程。下面以 MDK4 开发环境为例，介绍如何将系统运行起来。
+
+### 硬件连接
+
+使用 ESLinkⅡ (自带 CDC 串口)或 Jlink 等调试工具连接开发板到 PC，拨动开关选择使用调试工具供电或使用外部电源供电。若使用 Jlink 等调试工具，还需要将 UART5_TX(PB13)、UART5_RX(PB12)、GND 接到串口工具上。
+
+使用ESlinkⅡ(mini)连接开发板如下图所示：
+
+ESLinkⅡ(mini) + HRSDK-GDB-ES8P508-V1.0
+
+![ESLinkII](figures/ESLinkII-mini.jpg)
+
+### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK4 工程，工程默认配置使用 JLink 下载程序，在通过 JLink 连接开发板的基础上，点击下载按钮即可下载程序到开发板，如果使用 ESLinkⅡ，则选择 "CMSIS-DAP Debugger"，连接正常后即可编译并下载程序到开发板。
+
+### 运行结果
+
+下载程序成功之后，系统会自动运行，观察串口输出的信息，同时开发板LED闪烁。
+

+msh />
+```
+## 3. 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 uart5 的功能，如果需使用 SPI 等更多高级功能，需要利用 ENV 工具对 BSP 进行配置，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=MDK4` 命令重新生成工程。
+
+更多 Env 工具的详细介绍请参考 [RT-Thread 文档中心](https://www.rt-thread.org/document/site/)
