基本安裝設定

Yocto 項目至少需要 150G 存儲

在使用 Yocto 項目之前必須安裝必要的包

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
   build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
     xz-utils debianutils iputils-ping libsdl1.2-dev xterm curl

Update existing list of packages

$ sudo apt-get update

Install a few prerequisite packages which let apt use packages over HTTPS

$ sudo apt install apt-transport-https ca-certificates curl software-properties-common

Add Docker’s official GPG key for the official Docker repository to your system

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add

Set up the stable repository, add the Docker repository to APT sources

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Update the package database with the Docker packages from the newly added repo

$ sudo apt-get update

Install Docker

$ sudo apt-get install docker-ce docker-ce-cli containerd.io

Download the Docker Script for MA35D1

$ git clone https://github.com/OpenNuvoton/MA35D1_Docker_Script.git

Enter docker-yocto folder, setup docker image, and select folder to be share

$ ./build.sh                             It may take one hour to get 710 files.
Please enter absolute path for shared folders(eg:/home/<user name>) :

Enter docker image, and your command line head will be like nuvoton@a24d9e06abe3:~$

$ ./join.sh
nua3500_nuvoton
nuvoton@a24d9e06abe3:~$

Create a folder name yocto under /share

nuvoton@a24d9e06abe3:~/share$ mkdir yocto

The first time you use repo, you need to set up the GIT environment

nuvoton@a24d9e06abe3:~/share/yocto$  git config --global user.email "test@test.test.test"
nuvoton@a24d9e06abe3:~/share/yocto$  git config --global user.name "test"
nuvoton@a24d9e06abe3:~/share/yocto$  git config --global http.sslverify false

Go to /share/yocto to setup repo path

nuvoton@a24d9e06abe3:~/share/yocto$ repo init -u https://github.com/OpenNuvoton/MA35D1_Yocto-v3.1.3.git -m meta-ma35d1/base/ma35d1.xml

Download the yocto project

nuvoton@a24d9e06abe3:~/share/yocto$ repo sync

Build Image by Yocto

Setup building configuration. The DISTRO option we usually use nvt-ma35d1-directfb

EVB :

~/yocto$ DISTRO=nvt-ma35d1-directfb MACHINE=ma35d1-evb source  sources/init-build-env build

SOM :

~/yocto$ DISTRO=nvt-ma35d1-directfb MACHINE=numaker-som-ma35d16a81 source  sources/init-build-env build

MACHINE 目前有 SOM 板 或 IOT 板，後面ma35d16a81是 板號，所以客戶可以做他自己的板子，用自己得板號。

MACHINE=numaker-som-ma35d16a81

MACHINE=numaker-iot-ma35d16f70 ( f7 => DDR 128MB )

MACHINE=numaker-iot-ma35d16f90 ( f9 => DDR 512MB )

test chip SOM :

~/yocto$ DISTRO=nvt-ma35d1-directfb MACHINE=ma35d1-tc-som source  sources/init-build-env build

(補充說明) 假設我要改build 不同的板號，從numaker-som-ma35d16a81 改成 numaker-iot-ma35d16f70，有兩個地方要改

1. local.conf 的 Machine 要改如下
2. 指定編譯 DISTRO=nvt-ma35d1-directfb MACHINE=numaker-iot-ma35d16f70 source sources/init-build-env build

Choose what Image you want to build

Image 包含Qt的版本 (建議)

bitbake nvt-image-qt5

小 Image 版本

bitbake core-image-minimal

Copy the image to SD

$ sudo dd if=nvt-image-qt5-evb-ma35d1-xxxxx.rootfs.sdcard of=/dev/sdb status=progress

Fast Application Development

Make a toolchain installer

$ bitbake nvt-image-qt5 -c populate_sdk
(This may take about 1 hour )

Go to the following path and execute the shell file

~build/tmp-glibc/deploy/sdk $  ./oecore-x86_x64-aarch64-toolcahin-5.5-dunfell.sh

Add toolchain to environment variables

$ source /usr/local/oecore-x86_64/environment-setup-aarch64-poky-linux

Create the source code file for this example: helloworld.c

#include <stdio.h>
int main() {
    // printf() displays the string inside console
    printf(“Hello, World!\n”);
    return 0;
}

Compile it

$ $CC helloworld.c -o helloworld
