+
+## 简介
+
+本文档为 RT-Thread 开发团队为飞凌 OK1061-S 开发板提供的 BSP (板级支持包) 说明。
+
+主要内容如下：
+
+- 开发板资源介绍
+- BSP 快速上手
+- 进阶使用方法
+
+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。在进阶使用指南章节，将会介绍更多高级功能，帮助开发者利用 RT-Thread 驱动更多板载资源。
+
+## 开发板介绍
+
+
+OK1061-S 开发板基于 NXP 公司 i.MX RT1061 跨界处理器设计，搭载 ARM Cortex -M7 内核，集微控制器的低功耗、易用性与应用处理器的高性能、高扩展性于一体。底板+核心板分离结构，采用邮票孔封装设计，核心板体积小巧仅30×30×3mm，引脚数量100PIN，间距1.0mm，方便嵌入各种尺寸的设备中。
+
+
+运行频率 528MHz(商业级为600MHz)，1MB片上SRAM多达 512KB 可配置为紧耦合存储器 (TCM)，QSPI-Nor Flash 支持容量4MB。底板+核心板分离结构，采用邮票孔封装设计，核心板体积小巧仅30×30×3mm，引脚数量100PIN，间距1.0mm，方便嵌入各种尺寸的设备中。为了更大限度发挥CPU特性，核心板引出CPU大部分功能，同时配备了一系列特别适合实时应用的功能，例如高速GPIO 、CAN-FD，以及同步并行 NAND/NOR/PSRAM 控制器。工业级设计核心板，运行温宽 -40℃~+85℃；为了更加方便客户评估使用，OK1061-S开发板引出UART、Ethernet*2、USB、CAN、CAN FD、HS_GPIO、PWM、ADC等丰富外设功能；支持裸机，FreeRTOS等实时系统。
+
+
+开发板外观如下图所示：

+
+## Keil IDE 使用说明
+
+使用说明分为如下两个章节：
+
+- 快速上手
+
+    本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+- 进阶使用
+
+    本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。
+
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用数据线连接开发板到 PC，打开电源开关。
+
+#### 编译下载
+
+首先需要将需要将 RT1061 的 FLASH 下载算法（board目录下的 MIMXRT_QSPIFLASH.FLM 文件）拷贝到 `MDK 安装路径/ARM/Flash` 文件夹中。双击 `project.uvprojx` 文件，打开 MDK5 工程，在调试选项里 `Flash Download` 一栏中按照下图所示选择下载算法并保存设置：
+
+<figure>
+  <img src = "./figures/flash.png" width=360>
+</figure>
+
+编译工程，工程默认配置使用 CMSIS-DAP 下载程序，在通过 CMSIS-DAP 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。
+
+#### 运行结果
+
+下载程序成功之后，系统会自动运行，观察开发板上 LED 的运行效果，蓝色 LED 会周期性闪烁。
+
+连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息:
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     5.0.1 build May  9 2023 15:35:22
+ 2006 - 2022 Copyright by RT-Thread team
+msh >
+```
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 串口 1 的功能，如果需使用更多高级外设功能，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=mdk5/iar` 命令重新生成工程。
+
