Installation Preparations ​

This section describes the compatibility of the hardware and software and the related configurations and preparations required for the installation.

Obtaining the Installation Source ​

Before installation, obtain the openEuler Raspberry Pi image and its verification file.

1. Visit openEuler Repo.
2. Choose openEuler 22.03 LTS SP2.
3. Click raspi_img. The download list of Raspberry Pi images is displayed.
4. Click openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz to download the openEuler Raspberry Pi image to the local PC.
5. Click openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz.sha256sum to download the verification file of the openEuler Raspberry Pi image to the local PC.

Verifying the Image Integrity ​

Overview ​

During package transmission, to prevent software packages from being incompletely downloaded due to network or storage device problems, you need to verify the integrity of the software packages after obtaining them. Only the software packages that pass the verification can be deployed.

Compare the verification value recorded in the verification file with the verification value that is manually calculated to determine whether the software package is complete. If the two values are the same, the downloaded file is complete. Otherwise, the downloaded file is incomplete and you need to obtain the software package again.

Prerequisites ​

Before verifying the integrity of the image file, ensure that the following files are available:

Image file: openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz Image file: openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz

Verification file: openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz.sha256sum Verification file: openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz.sha256sum

Procedures ​

To verify the file integrity, perform the following procedures:

1. Obtain the verification value from the verification file. Run the following command:

   shell

   cat openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz.sha256sum

2. Calculate the SHA256 verification value of the file. Run the following command:

   shell

   sha256sum openEuler-22.03-LTS-SP2-raspi-aarch64.img.xz

   After the command is executed, the verification value is displayed.

3. Check whether the verification values obtained from the step 1 and step 2 are consistent.

   If they are consistent, the downloaded file is not damaged. Otherwise, the downloaded file is incomplete and you need to obtain the file again.

Installation Requirements ​

If the openEuler OS is installed in the Raspberry Pi environment, the Raspberry Pi environment must meet the following requirements.

Hardware Compatibility ​

Currently, the openEuler Raspberry Pi image supports the 3B, 3B+, and 4B versions.
