### 3.2 CANN Upgrading (taking 8.1.RC1 version as an example)

If the current CANN version does not meet the development requirements, the CANN version can be upgraded according to the following steps.

#### 3.2.1 Toolkit Upgrading

Step 1 Use the `CTRL+ALT+T` or click on the icon with `$_` at the bottom of the page to open the terminal and switch to the root user.

![environment-setup-1-14](https://mindspore-website.obs.cn-north-4.myhuaweicloud.com/website-images/r2.7.0rc1/tutorials/source_zh_cn/orange_pi/images/environment_setup_1-14.png)

Switch the root user, root user password: Mind@123.

```bash

# Open a terminal on the development board and run the following command

(base) HwHiAiUser@orangepiaipro:~$ su - root
 Password:
(base) root@orangepiaipro: ~#

```

Step 2 Remove installed CANN packages to free up disk space and prevent installing new CANN packages from reporting low disk space errors.

```bash

(base) root@orangepiaipro: ~# cd /usr/local/Ascend/ascend-toolkit
(base) root@orangepiaipro: /usr/local/Ascend/ascend-toolkit # rm -rf *

```

Step 3 Open the official website of Ascend CANN to access the community version of the resource [download address](https://www.hiascend.com/developer/download/community/result?module=cann), download the required version of the toolkit package. Taking 8.1.RC1 version as an example, as shown below:

![environment-setup-1-15](../../source_zh_cn/orange_pi/images/environment_setup_1-15.png)

> Execute the following commands to select the aarch64 or x86_64 package according to the actual output of the environment.

```bash
  uname -a
   ```

Step 4 Go to the Toolkit package download directory.

```bash
(base) root@orangepiaipro: /usr/local/Ascend/ascend-toolkit# cd /home/HwHiAiUser/Downloads
```

> Orange Pi AI Pro browser file default download directory: /home/HwHiAiUser/Downloads, users should synchronize to modify the path in the above command when changing the save path.

Step 5 Add execution permissions to the CANN package.

```bash
(base) root@orangepiaipro: /home/HwHiAiUser/Downloads# chmod +x ./Ascend-cann-toolkit_8.1.RC1_linux-aarch64.run
```

Step 6 Execute the following command to upgrade the software.

```bash
(base) root@orangepiaipro: /home/HwHiAiUser/Downloads#./Ascend-cann-toolkit_8.1.RC1_linux-aarch64.run --install
```

Type Y when this prompt pops up during installation, then press Enter to continue the installation. This process takes about 10-15 minutes, please be patient.

After the upgrade is completed, if the following message is displayed, the software upgrade is successful:

```bash
xxx install success

```

- xxx indicates the actual package name of the upgrade.

- Path after installing the upgrade (default installation path for root user as an example): "/usr/local/Ascend/ascend-toolkit/"

> If the output is incorrect, you need to follow the above steps to upgrade Toolkit again.

Step 7 Load environment variables.

```bash

(base) root@orangepiaipro: /home/HwHiAiUser/Downloads # source ~/.bashrc

```

#### 3.2.2 Kernels Upgrading

> The binary arithmetic package Kernels relies on the CANN package Toolkit. To perform the upgrade, the current environment needs to have the matching version of Toolkit installed and installed by the root user.

Step 1 Open a terminal and switch the root user.

Password for root user: Mind@123.

```bash

# Open a terminal on the development board and run the following command

(base) HwHiAiUser@orangepiaipro:~$ su - root
 Password:
(base) root@orangepiaipro: ~#

```

Step 2 Execute the following command to get the development board NPU model number.

```bash
npu-smi info
```

Step 3 Open the official website of Ascend CANN to access the community edition resources [download address](https://www.hiascend.com/developer/download/community/result?module=cann), and download the kernel package that is consistent with the CANN package version and matches the NPU model. As shown in the figure below:

![environment-setup-1-18](../../source_zh_cn/orange_pi/images/environment_setup_1-18.png)

Step 4 Go to the Kernels package download directory.

```bash
(base) root@orangepiaipro: /usr/local/Ascend/ascend-toolkit# cd /home/HwHiAiUser/Downloads
```

> Default download directory of OrangePi AIpro browser file: /home/HwHiAiUser/Downloads

Step 5 Add execution permissions to the kernels package.

```bash
(base) root@orangepiaipro: /home/HwHiAiUser/Downloads# chmod +x ./Ascend-cann-kernels-310b_8.1.RC1_linux-aarch64.run
```

Step 6 Execute the following command to upgrade the software.

```bash
(base) root@orangepiaipro: /home/HwHiAiUser/Downloads#./Ascend-cann-kernels-310b_8.1.RC1_linux-aarch64.run --install
```

After the upgrade is completed, if the following message is displayed, the software upgrade is successful:

```bash
xxx install success
```

- xxx indicates the actual package name of the upgrade.

- Path after installing the upgrade (default installation path for root user as an example): "/usr/local/Ascend/ ascend-toolkit/latest/opp/built-in/op_impl/ai_core/tbe/kernel".

> If the output is incorrect, you need to follow the above steps to upgrade Kernels again.

## 4. MindSpore Upgrading

### 4.1 Querying MindSpore Version

Step 1 Use `CTRL+ALT+T` or click on the icon with `$_` at the bottom of the page to open the terminal and keep the HwHiAiUser user logged in.

![environment-setup-1-14](../../source_zh_cn/orange_pi/images/environment_setup_1-14.png)

Step 2 Execute the following command to obtain version information.

```bash
(base) HwHiAiUser@orangepiaipro:~$ pip show mindspore
```

![environment-setup-1-24](../../source_zh_cn/orange_pi/images/environment_setup_1-24.png)

If the current MindSpore version does not meet the development requirements, the MindSpore version can be upgraded according to the following methods.

### 4.2 Installing the Official Version of the Website (Taking MindSpore 2.6.0 as an example)

#### 4.2.1 MindSpore Upgrading

Please note that both installation methods for MindSpore need to be performed under the HwHiAiUser user. Choose either method for installation.

Method 1: Use the CTRL+ALT+T shortcut key or click on the icon with $_ at the bottom of the page to open the terminal, keep the HwHiAiUser user logged in, and run the pip install command directly on the terminal.

```bash
(base) HwHiAiUser@orangepiaipro:~$ pip install mindspore==2.6.0
```

Method 2: Use the CTRL+ALT+T shortcut key or click on the icon with $_ at the bottom of the page to open the terminal, refer to [MindSpore official website installation tutorial](https://www.mindspore.cn/install/en) to install.

```bash

# Confirm the operating system and programming language, and the default environment of the OrangePi AIpro development board is linux-aarch64 and python3.9
```

#### 4.2.2 Installation Verification

```bash
(base) HwHiAiUser@orangepiaipro:~$ python -c "import mindspore;mindspore.set_context(device_target='Ascend');mindspore.run_check()"
```

If the output is as follows, it indicates that MindSpore has been successfully installed.

```bash
MindSpore version: 2.6.0
The result of multiplication calculation is correct, MindSpore has been installed on platform [Ascend] successfully!
```

> If the output is incorrect, it needs to be upgraded again according to the MindSpore upgrade method in 4.2.1.
