​ 图4-2-1-2 选择下载对应的200DK
解压后，将Ascend310-source-minirc.tar.gz上传至200DK任一目录下，例如/opt。
2) 在200DK执行su root，切换至root用户。
3) 通过如下命令进行安装依赖，该步骤200DK需要联网。
```bash
apt-get install -y python make gcc unzip bison flex libncurses-dev squashfs-tools bc
```
执行cd /opt，进入源码包所在目录，例如/opt。
4) 执行解压命令，解压源码包“Ascend310-source-minirc.tar.gz”。
```bash
tar -xzvf Ascend310-source-minirc.tar.gz
```
5) 执行命令cd source，进入source目录。
6) 配置内核。
a) 执行如下命令，进入内核目录。
cd kernel/linux-4.19
b) 执行如下命令，读取内核默认配置。
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- mini_defconfig
c) 执行如下命令，并使能相关配置。
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig
i. 按以下选项配置内核，“Y”键选择*（编译进内核），“M”键选择M（编译成模块）。

ii. 选择“Save”，保存配置，系统默认配置文件为.config。
d) 执行如下命令，保存配置。
cp -f .config arch/arm64/configs/mini_defconfig
e) 返回source目录。
cd /opt/source
7) 修改设备树。
a. 执行如下命令，修改文件hi1910-asic-1004.dts。
```bash
vim dtb/hi1910-asic-1004.dts
```
修改bootargs字段如下，使能uart0串口配置。
```
