+	![download_deverlopkit](https://images.gitee.com/uploads/images/2020/0729/141200_ebfaba44_5395865.png "屏幕截图.png")
+
+2. Download the SD card making script and ubuntu16.04.3-arm.iso.    
+	Run the following command in the $HOME directory of a common user (for example, the ascend user) in the local environment to download code from the tools repository:   
+	**git clone https://gitee.com/ascend/tools.git**   
+	(If Git is not installed, run the sudo apt-get install git command to install it.)    
+
+	Go to the C32 card making directory:  
+	**cd $HOME/tools/makesd/for_1.3x.0.0/**  
+	```powershell  
+	ascend@ubuntu:~$ git clone https://gitee.com/ascend/tools.git
+	Cloning into 'tools'...

+	ascend@ubuntu:~$ cd tools/makesd/for_1.3x.0.0/
+	ascend@ubuntu:~/tools/makesd/for_1.3x.0.0$ ls
+	make_sd_card.py  make_ubuntu_sd.sh  README.md
+	ascend@ubuntu:~/tools/makesd/for_1.3x.0.0$ ^C
+	ascend@ubuntu:~/tools/makesd/for_1.3x.0.0$ 
+	```  
+	Download the ubuntu16.04.3-arm.iso image:  
+	**wget http://old-releases.ubuntu.com/releases/16.04.3/ubuntu-16.04.3-server-arm64.iso**  
+	(The file size is 744 MB. It takes about 8 minutes to download the file.)  
+	
+	After the download is complete, grant 755 permission to the script and image:  
+	**chmod 755 make_sd_card.py make_ubuntu_sd.sh ubuntu-16.04.3-server-arm64.iso**  
+	
+3. Save the downloaded card making package to the $HOME/tools/makesd/for_1.3x.0.0 directory of the common user.  
+	```powershell  
+	ascend@ubuntu:~/tools/makesd/for_1.3x.0.0$ ll
+	total 80920
+	drwxr-xr-x 2 ascend ascend     4096 Jul 28 04:33 ./
+	drwxr-xr-x 4 ascend ascend     4096 Jul 28 04:23 ../
+	-rw-r--r-- 1 ascend ascend 74438310 Jul 28 04:32 mini_developerkit_1.32.0.B080.rar
+	-rwxr-xr-x 1 ascend ascend    17633 Jul 28 04:23 make_sd_card.py*
+	-rwxr-xr-x 1 ascend ascend    23797 Jul 28 04:23 make_ubuntu_sd.sh*

+	ascend@ubuntu:~/tools/makesd/for_1.3x.0.0$ 
+	```  
+
+4. Connect the card reader inserted with an SD card to the Ubuntu server to make a bootable SD card  
+
+	Switch to the root user and prepare for card making:  
+	**su root**
+
+	Run the SD card making script:   
+	**python3 make_sd_card.py local /dev/sdb**   
+	(Note: /dev/sdb is the device name of the SD card. You can run the fdisk -l command as the root user to query the device name.)   
+	![mksd2](https://images.gitee.com/uploads/images/2020/0729/140246_f7c541a0_5395865.png)  
+	When a message is displayed, asking you whether to continue the installation, enter **Y**.  
+	Wait for about 7 minutes. The message "Make SD Card successfully!" is displayed, indicating that the SD card has been made successfully.  
+	
+5. Power on the Atlas 200 DK.  
+	Insert the SD card into the Atlas 200 DK, power on the Atlas 200 DK, and connect it to the Ubuntu server.  
+	**Note: During the upgrade of the Atlas 200 DK, two LED indicators blink. When the four LED indicators are on, the upgrade is successful. The upgrade takes about 5–10 minutes.**
