Using Linux kernel on an Orange Pi 4.
This page is focused just on building a kernel. For the related required components, see Linux on Orange Pi 4.
Prerequisite: U-Boot on Orange Pi 4
Next steps: rootfs on Orange Pi 4
TODO: THIS!
Contents
Overview
In order to build a Linux kernel you'll need:
- Linux kernel source
- (optional) Patches to add support for the specific hardware
- Cross-compilation toolchain if building on a different device than Orange Pi 4
Setup
Linux kernel
TODO: Git clone
Kernel patches
TODO: Switch to a Mainline Linux. Right now we're using a BSP Linux kernel which already supports Orange Pi 4.
Cross-compilation
This is needed only if you're building on a different architecture, e.g. on an x86_64 computer.
TODO: Linaro + instructions?
CROSS_COMPILE=/path/to/toolchain/bin/aarch64-linux-gnu-
Compiling
TODO: compilation
Generate .config file
cd linux make ARCH=arm64 CROSS_COMPILE=$CROSS_COMPILE rk3399_linux_defconfig
Compile the kernel
CORES=4 # number of CPU cores
make ARCH=arm64 CROSS_COMPILE=$CROSS_COMPILE -j${CORES} rk3399-orangepi.img
TODO: Modules? Img to flash? boot.img
Flashing
dd if=boot.img of=sdb seek=32768
