STM32MP1 개발 환경 구축(5) - Cortex-A Developer Package 실행

 

Target Board	STM32MP157F-EV1(ST)
Host	PC - Ubuntu 22.04
목표	STM32MP1 개발 환경 구축 - Developer Package 실행

---

Developer Package 실행은 다음과 같다.

​

1. Linux kernel 빌드

2. U-Boot 빌드

 

설치 과정은 커널 및 U-Boot가 설치된 폴더의 README.HOW_TO.txt를 참조한다.

Linux kernel Compile 순서는 다음과 같다.

1-1. Pre-requisite

1-2. Initialize cross-compilation via SDK

1-3. Prepare kernel source code

1-4. Manage kernel source code

1-5. Configure kernel source code

1-6. Compile kernel source code

1-7. Update software on board

1-8. Update Starter Package with kernel compilation outputs

 

1-1. 사전 준비

- OpenSTLinux SDK 설치 되어 있어야 함

- libncurses and libncursesw dev package libyaml-dev

PC $ cd linux-5.15.67/

PC $ sudo apt-get install libncurses5-dev libncursesw5-dev libyaml-dev

 

 

- mkimage 설치

PC $ sudo apt-get install u-boot-tools

 

 

- yaml (check dts) 설치

PC $ sudo apt-get install libyaml-dev

 

 

- git 설치

PC $ sudo apt-get install git-core gitk

 

1-2. cross-compilation via SDK

- SDK 환경 설정 스크립트 실행

PC $ source /home/본인PC이름/STM/Developer-package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

 

 

1-3. Prepare kernel source code

- ST 패치

PC $ for p in `ls -1 ../*.patch`; do patch -p1 < $p; done

 

 

1-5. Configure kernel source code

- fragment 적용

PC $ mkdir -p ../build

PC $ make ARCH=arm multi_v7_defconfig "fragment*.config"

 

- gcc 없다고 에러 메시지

- make 설치

PC $ sudo apt-get install make

 

- gcc 설치

PC $  sudo apt-get install gcc

 

- fragment 적용

PC $ make ARCH=arm multi_v7_defconfig "fragment*.config"

 

PC $ for f in `ls -1 ../fragment*.config`; do scripts/kconfig/merge_config.sh -m -r .config $f; done

 

PC $ yes '' | make ARCH=arm oldconfig

 

 

1-6. Compile kernel source code

- Kernel images 빌드(시간 오래 걸림)

PC $ make ARCH=arm uImage vmlinux dtbs LOADADDR=0xC2000040

 

 

- Kernel module 빌드(시간 오래 걸림)

PC $ make ARCH=arm modules

 

- Output build artifacts 생성

PC $ make ARCH=arm INSTALL_MOD_PATH="$PWD/../build/install_artifact" modules_install O="$PWD/../build"

 

PC $ mkdir -p $PWD/../build/install_artifact/boot/
PC $ cp $PWD/../build/arch/arm/boot/uImage $PWD/../build/install_artifact/boot/
PC $ cp $PWD/../build/arch/arm/boot/dts/st*.dtb $PWD/../build/install_artifact/boot/

 

- 생성 파일 확인
