+# 基于 EXT4 文件系统的 RT-Smart 用户态应用开发
+
+> 本文档环境为 `ubuntu 20.04`
+
+## 环境准备
+
+### 仓库
+
+`RT-Smart` 软件开源在 `https://github.com/RT-Thread/rt-thread.git` 本 `bsp` 的源码在 `https://github.com/RT-Thread/rt-thread/tree/master/bsp/qemu-virt64-aarch64`
+
+请 `clone` 此仓库以进行开发:
+
+```shell
+git clone https://github.com/RT-Thread/rt-thread.git
+```
+
+### pkgs
+
+pkgs 是 RT-Smart 的包管理软件，
+
+```shell
+mkdir -pv ~/.env/tools/
+git clone https://gitee.com/RT-Thread-Mirror/env.git ~/.env/tools/scripts
+export PATH=~/.env/tools/scripts:$PATH:$RTT_EXEC_PATH
+```
+
+### 添加 EXT4 软件包
+
+EXT4 是作为 RT-Smart 的一个软件包，因此我们需要使用 pkgs 去管理下载 EXT4 软件包
+
+首先进入 `bsp` 目录，也就是从 github 克隆的那个仓库，进入 `bsp/qemu-virt64-aarch64` 目录执行 `scons --menuconfig`。将 `> RT-Thread online packages > system packages > lwext4: an excellent choice of ext2/3/4 filesystem for microcontrollers.` 目录的选项激活，然后退出 `menuconfig`
+
+执行 `pkgs --update` 以下载软件包（需确保已将 `pkgs` 添加置环境变量）
+
+### 修改 SD 卡挂载方式
+
+将 `bsp` 的 `sd` 卡的挂载文件系统代码（`bsp/qemu-virt64-aarch64/applications/mnt.c`）修改为 ext 文件系统
+
+```c
+int mnt_init(void)
+{
+    if (rt_device_find("virtio-blk0"))
+    {
+        /* mount virtio-blk as root directory */
+        if (dfs_mount("virtio-blk0", "/", "ext", 0, RT_NULL) == 0)
+        {
+            rt_kprintf("file system initialization done!\n");
+        }
+    }
+
+    return 0;
+}
+INIT_ENV_EXPORT(mnt_init);
+```
+
+### 工具链
+
+首先进入到 `tools` 文件夹，下载工具链：
+
+```shell
+python3 get_toolchain.py aarch64
+```
+
+## 内核编译
+
+先在 `userapps` 目录下执行以下命令将编译器信息添加到环境变量
+
+```shell
+source smart-env.sh aarch64
+```
+
+随后进入 `bsp` 目录进行编译
+
+```shell
+scons -j8
+```
+
+将编译生成的产物复制到 `userapps` 目录下的 `prebuilt/qemu-virt64-aarch64-ext4/rtthread.bin` 处
+
+## 用户态编译
+
+先在 `userapps` 目录下执行以下命令将编译器信息添加到环境变量
+
+```shell
+source smart-env.sh aarch64
+```
+
+随后直接在此目录执行编译命令即可编译事先准备好的用户态示例
+
+```shell
+scons -j8 --verbose
+```
+
+产物存放在 `root/bin` 目录下
+
+## sd 卡打包
+
+在 `userapps` 目录执行以下命令将 `root` 目录打包成一个 `500M` 大小的镜像包并放入 `prebuilt/qemu-virt64-aarch64-ext4/rootfs.img`
+
+```
+tools/make_ext4fs/make_ext4fs -l 500M prebuilt/qemu-virt64-aarch64-ext4/rootfs.img root
+```
+
+## 运行 qemu
+
+在 `userapps` 目录下的 `prebuilt/qemu-virt64-aarch64-ext4` 目录执行 `qemu.sh` 以运行 qemu
+
+随后可以执行 `bin/hello.elf` 看是否正确输出`hello world!`字样
+
+```log
