Configuring the build

Prerequisites

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

• Setup Cross Compiler
• Install these packages: shareutils, swing

Setup U-Boot environment

• WorkDir:

mkdir -p compulab-bootloader/build && cd compulab-bootloader
export BUILD=$(pwd)/build

• 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

• Clone the source code:

git clone --branch u-boot-compulab_v2021.04 https://github.com/compulab-yokneam/u-boot-compulab.git
cd u-boot-compulab

Create U-boot binary

• Apply the machine Config

make O=${BUILD} ${MACHINE}_defconfig

• Build

nice make -j`nproc` O=${BUILD} flash.bin

• Result

ls -al ${BUILD}/flash.bin
