Kernel Build Manual

Prerequisites

It is up to developers to prepare the host machine; it requires:

• Setup Cross Compiler

CompuLab Linux Kernel setup

• WorkDir:

mkdir -p compulab-kernel/build && cd compulab-kernel

• Set a CompuLab machine:

Machine	Command Line
ucm-imx8m-plus	export MACHINE=ucm-imx8m-plus
som-imx8m-plus	export MACHINE=som-imx8m-plus
iot-gate-imx8plus	export MACHINE=iot-gate-imx8plus
ucm-imx93	export MACHINE=ucm-imx93

• Clone the source code:

git clone -b linux-compulab_v5.15.71 https://github.com/compulab-yokneam/linux-compulab.git
cd linux-compulab

Compile the Kernel

• Apply the default CompuLab config:

make ${MACHINE}_defconfig compulab.config

• Ussue menuconfig on order to change the default CompuLab configuration:

make menuconfig

• Build the kernel

nice make -j`nproc`

• Deploy the CompuLab Linux Kernel to CompuLab devices
