+# 芯来科技蜂鸟FPGA评估板 #
+
+## 简介
+
+**蜂鸟FPGA评估板** 是由芯来科技公司推出的用于测试评估芯来RISC-V内核处理器的FPGA评估板。
+
+更多关于 **蜂鸟FPGA评估板** 开发板的详细资料请参见 [蜂鸟FPGA评估板](https://nucleisys.com/developboard.php)
+
+### 板载资源
+
+| 硬件 | 描述 |
+| ---  | --- |
+| 内核 | Nuclei RISC-V N/NX/UX 内核 |
+| 架构 | RV32 or RV64 |
+| 主频 | 8MHz or uncertain freq |
+
+**注意**: 这个上面烧写的是FPGA bitstream文件，所以处理器内核版本根据型号来定，通过修改**rtconfig.py**中的**NUCLEI_SDK_CORE**.
+
+
+## 工具安装
+
+### 安装工具链
+
+请根据[安装Nuclei RISC-V GCC Toolchain和OpenOCD](https://doc.nucleisys.com/nuclei_sdk/quickstart.html#setup-tools-and-environment) 来安装依赖的工具。
+
+### 添加环境变量
+
+将Nuclei RISC-V GCC Toolchain和OpenOCD的环境变量进行设置。
+
+#### Windows
+
+假设工具安装在 **D:\Software\Nuclei**目录下, 则可以修改系统环境变量**PATH**,
+将**D:\Software\Nuclei\gcc\bin;D:\Software\Nuclei\openocd\bin;**增加到**PATH**中。
+
+或者在ENV工具命令行中运行
+
+~~~cmd
+set PATH=D:\Software\Nuclei\gcc\bin;D:\Software\Nuclei\openocd\bin;%PATH%
+~~~
+
+#### Linux
+
+假设工具安装在 **~/Software/Nuclei**目录下, 通过在Linux的``.bashrc``增加如下一行代码
+来添加环境变量。
+
+~~~bash
+export PATH=~/Software/Nuclei/gcc/bin:~/Software/Nuclei/openocd/bin:$PATH
+~~~
+
+或者在ENV工具命令行中运行
+
+~~~bash
+export PATH=~/Software/Nuclei/gcc/bin:~/Software/Nuclei/openocd/bin:$PATH
+~~~
+
+**注意**: 对应的RISC-V GCC和OPENOCD的路径请替换成自己安装的路径。
+
+## 烧写及执行
+
+### [驱动设置](https://nucleisys.com/developboard.php)
+
+### 编译程序
+
+下载好[RT-Thread](https://github.com/RT-Thread/rt-thread)的代码和[ENV工具](https://www.rt-thread.org/document/site/tutorial/env-video/)以后。
+
+按照ENV工具的教程, 在**rt-thread\bsp\nuclei\hbird_eval**目录打开ENV工具命令行。
+
+**注意**: 请确保Nuclei GCC和Nuclei OpenOCD的路径设置正确无误。
+
+1. 运行 ``pkgs --update``来下载最新的依赖的**Nuclei SDK**开发包
+2. **可选**: 运行 ``menuconfig``来进行内核配置
+3. 运行 ``scons -c``清理之前的编译结果
+4. 根据你当前评估的Nuclei RISC-V内核情况，修改 ``rtconfig.py``中的``NUCLEI_SDK_CORE``和``NUCLEI_SDK_DOWNLOAD``参数。
+   - ``NUCLEI_SDK_CORE``可选的参数为[Supported Nuclei Cores](https://doc.nucleisys.com/nuclei_sdk/develop/buildsystem.html#core)
+   - ``NUCLEI_SDK_DOWNLOAD``可选的参数为``ilm``,``flash``或者``flashxip``, 关于该选项的说明参见[Supported Download Modes](https://doc.nucleisys.com/nuclei_sdk/develop/buildsystem.html#download)
+   - 假设你手头拿到的Nuclei评估处理器内核为N307(rv32imafc), 想程序运行模式为``flash``,
+     则修改``NUCLEI_SDK_CORE``为``n307``, ``NUCLEI_SDK_DOWNLOAD``为``flash``.
+5. 修改完对应的``rtconfig.py``参数配置并保存后，运行 ``scons``来进行代码的编译
+
+### 下载程序
+
+在保证程序能够正常编译后, 在相同ENV终端执行``scons --run upload``进行代码的下载。
+
+正常下载的输出如下:
+
+~~~
+scons: Reading SConscript files ...
+Supported downloaded modes for board hbird_eval are ('ilm', 'flash', 'flashxip'), chosen downloaded mode is ilm

+## 驱动支持情况
+
+| 驱动 | 支持情况  |  备注  |
+| ------ | ----  | :------:  |
+| UART | 支持 | 蜂鸟开发板载串口是UART0 |
+
+**注:**
+
+- 适配RT-Thread的驱动框架的代码在 [../libraries/hbird/HAL_Drivers](../libraries/hbird/HAL_Drivers)目录下。
+- 如果有开发者想适配更多的驱动, 请在对应目录下增加驱动适配支持。
+- 目前串口读取功能在主频为8MHz情况下需要工作在57600bps
+- 目前串口读取没有采用中断的方式进行，而是采用单独的任务来读取，等中断信号接入后可以直接中断方式读取
