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.
- Visit openEuler Repo.
- Choose openEuler 21.09.
- Click raspi_img. The download list of Raspberry Pi images is displayed.
- Click openEuler-21.09-raspi-aarch64.img.xz to download the openEuler Raspberry Pi image to the local PC.
- Click openEuler-21.09-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-21.09-raspi-aarch64.img.xz
Verification file: openEuler-21.09-raspi-aarch64.img.xz.sha256sum
Procedures
To verify the file integrity, perform the following procedures:
Obtain the verification value from the verification file. Run the following command:
cat openEuler-21.09-raspi-aarch64.img.xz.sha256sum
Calculate the SHA256 verification value of the file. Run the following command:
sha256sum openEuler-21.09-raspi-aarch64.img.xz
After the command is executed, the verification value is displayed.
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+, 4B and 400 versions.
