# 基于麻雀D1运行 RT-Smart
|
|||
|
|
|
|||
|
|
### 下载代码
|
|||
|
|
|
|||
|
|
下载 RT-Smart 用户态应用代码：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
git clone https://github.com/RT-Thread/userapps.git
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
进入到 `userapps` 目录，克隆 RT-Thread rt-smart 分支
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
git clone -b rt-smart https://gitee.com/rtthread/rt-thread.git
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 配置工具链
|
|||
|
|
|
|||
|
|
在 userapps\tools 目录下运行 `get_toolchain.py` 的脚本，会下载对应的工具链并展开到 userapps\tools\gun_gcc 目录。后面的工具链名称可以是 arm | riscv64。
|
|||
|
|
|
|||
|
|
因为 D1S 是 RISCV-64 架构的，所以输入下面的命令：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
python3 get_toolchain.py riscv64
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在 userapps 目录下，运行 `smart-env.sh` 配置工具链路径，目前支持的参数可以是 arm | riscv64
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
source smart-env.sh riscv64
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 编译内核程序
|
|||
|
|
|
|||
|
|
进入 `rt-thread/bsp/allwinner/d1s` 目录下，执行以下命令拉取一下软件包
|
|||
|
|
|
|||
|
|
* 注：若系统没有安装 env，需要手动输入 `scons --menuconfig` 命令手动下载 env
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
source ~/.env/env.sh
|
|||
|
|
pkgs --update
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
使用 scons 命令进行编译，编译成功后会在 `userapps/rt-thread/bsp/allwinner/d1s` 目录下生成 sd.bin，这个文件就是我们需要烧录到开发板中的文件，它包括了 uboot.dtb，opensbi，rtthread.bin。
|
|||
|
|
|
|||
|
|
### 烧录程序
|
|||
|
|
|
|||
|
|
1、首先准备一张容量在 128G 以内的空白 TF卡
|
|||
|
|
|
|||
|
|
2、使用 fdisk 分区。将 TF卡 挂载到 ubuntu 系统后，使用 df 查看设备路径。笔者使用的 32GB TF卡，扇区大小 512 字节，我们需要预留前 8M 的空间，那么计算得知分区扇区开始于：16384，使用命令：`sudo fdisk /dev/sdb`，选择：o，n，p，1，16384，回车。
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
Command (m for help): o
|
|||
|
|
Created a new DOS disklabel with disk identifier 0x3668b987.
|
|||
|
|
|
|||
|
|
Command (m for help): n
|
|||
|
|
Partition type
|
|||
|
|
p primary (0 primary, 0 extended, 4 free)
|
|||
|
|
e extended (container for logical partitions)
|
|||
|
|
Select (default p): p
|
|||
|
|
Partition number (1-4, default 1): 1
|
|||
|
|
First sector (2048-62410751, default 2048): 16384
|
|||
|
|
Last sector, +sectors or +size{K,M,G,T,P} (16384-62410751, default 62410751):
|
|||
|
|
|
|||
|
|
Created a new partition 1 of type 'Linux' and of size 29.8 GiB.
|
|||
|
|
|
|||
|
|
Command (m for help): w
|
|||
|
|
The partition table has been altered.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
正确的分区效果如下：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
然后格式化 sdb1 分区为 fat32 格式：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
$ sudo mkfs -t fat /dev/sdb1
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
这里可以使用 **Gparted** 工具可视化查看一下分区状况：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
3、接下来使用以下命令烧录 RT-SMART 内核：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
sudo dd if=boot0_sdcard_sun20iw1p1.bin of=/dev/sdb bs=1024 seek=8
|
|||
|
|
sudo dd if=sd.bin of=/dev/sdb bs=1024 seek=56
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
* 注：**boot0_sdcard_sun20iw1p1.bin** 文件在 `userapps/rt-thread/bsp/allwinner/d1s/tools` 路径下
|
|||
|
|
* 这里的 /dev/sdb 设备要根据自己的选择
|
|||
|
|
|
|||
|
|
下面是烧录成功的显示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 启动 RT-Smart
|
|||
|
|
|
|||
|
|
方式二（TF 卡）启动：
|
|||
|
|
|
|||
|
|
此时将 TF 卡放入开发板，串口0（底部排针的7，8脚），串口波特率 500000，然后上电，如下 RT-Smart 已经成功启动
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|

### 编译用户态程序
|
|||
|
|
|
|||
|
|
进入 `userapps` 目录下，使用 scons 编译用户态程序，编译好的文件会生成在 `root/bin` 目录下。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 运行用户态程序
|
|||
|
|
|
|||
|
|
从 `root/bin` 目录下拷贝出 hello 程序，到 TF卡 的文件系统中。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
拔出 TF 卡，插入到开发板，上电。即可体验属于自己的 helloworld 程序了。
|
|||

|
|||
