+# 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:

+
+### 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
+

-VMM BSP on realview-pb-a8
-
-This is a demo program that run RT-Thread VMM(Virtual Machine Module) on
-the single core RealView-PB-A8.
-
-To compile it, you need buildroot and a linux 3.8.x source tree. You should
-build the patched Linux kernel and builroot before building the VMM. This
-directory has a "mk.sh" helper script to build both the RT-Thread, Linux kernel
-module and the ramdisk.
-
-Linux console is serial0 and RT-Thread console is serial1.
