raspberrypi-kernel

English | 简体中文

Description

The kernel for running on Raspberry Pi.

This repository is based on openEuler kernel which is merged patches of Raspberry Pi kernel.

Architecture Requirements

Hardware: Raspberry Pi 3B/3B+/4B.

Architecture: AArch64.

Compiling

Compile kernel and kernel modules.

1. Prepare compile environment

   OS: openEuler or CentOS 7/8;

   Architecture: AArch64.

   You follow the documents of raspberrypi to cross-compile this kernel.

2. Download source

   You need download different branches of different repositories according to the kernel version.

   1. Kernel 5.10

      • openEuler 21.09: git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-21.09 && cd raspberrypi-kernel
      • openEuler 21.03: git clone git@gitee.com:openeuler/kernel.git -b openEuler-21.03 && cd kernel

   2. Kernel 4.19

      • openEuler 20.03 LTS: git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.03-LTS && cd raspberrypi-kernel
      • openEuler 20.09: git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-20.09 && cd raspberrypi-kernel

3. Load default settings

   You need load different settings according to the kernel version.

   1. Kernel 5.10

      • openEuler 21.09: make bcm2711_defconfig
      • openEuler 21.03: make bcm2711_defconfig

   2. Kernel 4.19

      • openEuler 20.03 LTS: make openeuler-raspi_defconfig
      • openEuler 20.09: make openeuler-raspi_defconfig

   The corresponding defconfig file is in . /arch/arm64/configs.

4. Compile kernel

   make ARCH=arm64 -j4

5. Create directory for compiling kernel modules

   mkdir ../output

6. Compile kernel modules

   make INSTALL_MOD_PATH=../output/ modules_install

Now, the kernel compilation is complete.

Installation

Refer to raspberrypi Repository for details about how to use this compiled kernel to build openEuler image for Raspberry Pi.
