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. Log in to the openEuler Community website.

  2. Click Download.

  3. Click the Link provided after Download ISO. The download list is displayed.

  4. Click openEuler-20.03-LTS-SP1. The openEuler 20.03 LTS SP1 version download list is displayed.

  5. Click Raspberry Pi. The Raspberry Pi image download list is displayed.

    • aarch64: image of the AArch64 architecture
  6. Click aarch64 to download the Raspberry Pi AArch64 image download list.

  7. Click openEuler-20.03-LTS-SP1-raspi-aarch64.img.xz to download the openEuler Raspberry Pi image to the local PC.

  8. Click openEuler-20.03-LTS-SP1-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-20.03-LTS-SP1-raspi-aarch64.img.xz

Verification file: openEuler-20.03-LTS-SP1-raspi-aarch64.img.xz.sha256sum

Procedure

To verify the file integrity, perform the following procedure:

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

    $ cat openEuler-20.03-LTS-SP1-raspi-aarch64.img.xz.sha256sum
    
  2. Calculate the SHA256 verification value of the file. Run the following command:

    $ sha256sum openEuler-20.03-LTS-SP1-raspi-aarch64.img.xz
    

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

  3. Check whether the verification value calculated in step 1 is consistent with that calculated in step 2.

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