+# XuanTie - E901  Series
+
+## 一 简介
+
+### 1. 内核
+
+玄铁 E901+ 是基于 RISC-V 指令架构的低成本、高能效的 32 位嵌入式 CPU 处理器，用户可以以近似 8 位CPU 的成本获得 32 位嵌入式处理器的效率与性能。E901+ 处理器兼容 RV32E[M] [B]_Zc 指令架构，采用 16/32 位混合编码系统，指令系统与流水线硬件结构精简高效。同时支持配置协处理器接口，用于满足用户 DSA（Domain Specific Accelerator）需求，加速特定应用执行，并支持用户进行自定义指令扩展。
+
+E901+ 主要针对智能卡、智能电网、低成本微控制器、无线传感网络等嵌入式应用。
+
+### 2.特点
+
+E902 处理器体系结构的主要特点如下：
+
+E901+ 处理器体系结构的主要特点如下：
+

+### 3.BSP支持情况
+
+- 当前BSP支持下述内核：
+
+  ```asciiarmor
+  e901plusbm-cp
+  ```
+
+- 当前BSP默认设置的内核是e901plusbm-cp。
+
+- 当使用其他内核架构时需要修改，rtconfig.py文件中的`MCPU`字段。
+
+### 4.运行QEMU
+
+- BSP根目录下存在`qemu.bat`脚本，生成可执行文件后可点击该脚本直接启动QEMU.
+
+## 二 工具
+
+- 编译器： https://www.xrvm.cn/community/download?id=4433353576298909696
+- 模拟器： https://www.xrvm.cn/community/download?id=4397435198627713024
+
+注：若上述链接中的编译器与模拟器不能使用，可以使用下述CDK中的编译器与模拟器
+
+- SDK：https://www.xrvm.cn/community/download?id=4397799570420076544
+
+## 三 调试方法
+
+**下述调试方法以E902举例，本BSP操作方式一致**，搭建完成RT-Thread开发环境，在BSP根目录使用env工具在当前目录打开env。
+
+![](figures/1.env.png)
+
+使用前执行一次**menuconfig**命令，更新rtconfig.h配置，然后在当前目录执行**scons -j12**命令编译生成可可执行文件。
+
+<img src="figures/2.scons.png" alt="env" style="zoom: 95%;" />
+
+生成可执行文件，可以直接在命令行启动qemu或者配置vscode脚本借助vscode强大的插件进行图形化调试，qemu的相关命令可以查看玄铁qemu的[用户手册](https://www.xrvm.cn/community/download?id=4397435198627713024)，下述是启动qemu的命令，在powershell或命令行可直接执行下述命令，注意qemu需要导出至环境变量或者使用绝对路径。
+
+```shell
+qemu-system-riscv64 -machine smartl -nographic -kernel rtthread.elf -cpu e906
+```
+
+下述是使用vscode调试的展示。
+
+<img src="figures/3.vscode.png" alt="env" style="zoom: 63%;" />
+
+一起为RISC-V加油！
