+# JuiceVm 虚拟机 BSP 说明
+
+标签: Risc-V 64bit ima、JuiceVm
+
+---
+
+## 简介
+
+本文档为 JuiceVm 开发团队为 JuiceVm 虚拟机提供的 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。
+
+## 虚拟机介绍
+
+JuiceVm 虚拟机是 juice 开发的一款 Risc-V 64bit ima 虚拟机,Risc-V 64bit 虚拟机界面如下图所示:
+
+![开发板外观](static/juicevm_rtt.jpg)
+
+该虚拟机常用**资源**如下:
+
+- MCU:Risc-V 64bit ima,300MB RAM,支持M-MODE,S-MODE,
+- 常用外设
+ - UART0
+- 常用接口:UART
+- 调试接口: 标准 GDB 【TODO】
+
+更多详细信息请参考【Juice】[JuiceVm 虚拟机](https://whycan.com/t_5844.html)。
+
+## 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 | 暂不支持 | 即将支持 |
+| MMU(SV39) | 暂不支持 | 即将支持 |
+| UART | 支持 | UART0 |
+| SDIO | 暂不支持 | 即将支持 |
+| RTC | 暂不支持 | 即将支持 |
+| PWM | 暂不支持 | 即将支持 |
+| USB Device | 暂不支持 | 即将支持 |
+| USB Host | 暂不支持 | 即将支持 |
+
+## 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 GCC 开发环境。下面以 GCC 开发环境为例,介绍如何将系统运行起来。
+
+#### 编译下载
+##### toolchain 下载
+- 到 xpack-dev-tools 下载 [点击跳转](https://github.com/xpack-dev-tools/riscv-none-embed-gcc-xpack/releases/tag/v8.3.0-2.1)
+ ```
+ wget https://github.com/xpack-dev-tools/riscv-none-embed-gcc-xpack/releases/download/v8.3.0-2.1/xpack-riscv-none-embed-gcc-8.3.0-2.1-linux-x64.tar.gz
+ ```
+- 解压到/opt目录下
+ ```
+ tar vxf xpack-riscv-none-embed-gcc-8.3.0-2.1-linux-x64.tar.gz -C /opt
+ ```
+- 到rt-thread/bsp/juicevm目录下执行
+ ```
+ scons
+ ```
+- 下载 JuiceVm
+浏览器打开:
+https://whycan.com/files/members/1390/juice_vm_release_for_Linux_57ba985a.zip
+
+- 运行固件
+ ./juice_vm_for_Linux.out -a -g ./rtthread.bin
+
+#### 运行结果
+
+在console可以看到 RT-Thread 的输出信息:
+
+```c

+
+### 进阶使用
+
+此 BSP 默认只开启了 UART0 的功能和直接运行功能
+如果需使用更多功能,可以执行
+```
+./juice_vm_for_Linux.out
+```
+查看相关帮助信息开启调试和实时汇编输出功能
+## 注意事项
+
+编译参数请使用rv64ima,暂不支持Risc-V的c模块
