This slide provides instructions on how to quickly build an MA35D1 image
PC specification standard
。CPU: Intel i5-10400
。Memory: 16 GB DDR RAM
。Storage: 1 TB SSD Disk (200 GB of which is empty space)
。Operation System: Linux OS or Linux Virtual Machine (VMware provide by Nuvoton)
。A MA35D1 Docker container
Refer to MA35D1 Quick Start –Environment Setup section

•Docker enables the packaging of code and its dependencies into containers.
•Each container is independent and based on the host OS, ensuring they operate in isolation without
impacting each other. Containers run more efficiently than virtual machines, resulting in faster
performance

Environment Setup (1/4)
$
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

This demo is under Ubuntu distribution. If you use virtual machine, ensure your RAM at least 5GB
Update existing list of packages
Install a few prerequisite packages which let apt use packages over HTTPS
Add Docker’s official GPG key for the official Docker repository to your system
Set up the stable repository, add the Docker repository to APT sources

Environment Setup (2/4)
$
sudo apt-get update
$
sudo apt install apt-transport-https ca-certificates curl software-properties-common
$ curl
-fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add
$
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Environment Setup (3/4)
$
sudo apt-get update
$
sudo apt-get install docker-ce docker-ce-cli containerd.io
$
git clone https://github.com/OpenNuvoton/MA35D1_Docker_Script.git

•Create a folder name yocto under /shared
•The first time you use repo, you need to set up the GIT environment
•Go to /share/yocto to setup repo path
•Download the yocto project and update ma35d1 source code

1. Setup building configuration. The DISTRO option we usually use nvt-ma35d1-directfb
After typing this command and if you want to change this setting, please modify /build/conf/local.conf
If you exit the docker container and join the docker container again, source the environment variables
Usage:
。MACHINE=<machine> DISTRO=<distro> source sources/init-build-env <build-dir>
<machine> machine name <distro> distro name <build-dir> build directory
Choose which DISTRO configuration you want to build
。nvt-ma35d1-directfb (sources/meta-nua3500/conf/distro/nvt-ma35d1-directfb.conf)
Choose which machine configuration you want to build
。numaker-som-ma35d16a81 (sources/meta-ma35d1/conf/machine/ numaker-som-ma35d16a81)
。numaker-iot-ma35d16f70 (sources/meta-ma35d1/conf/machine/ numaker-iot-ma35d16f70)
。numaker-iot-ma35d16f90 (sources/meta-ma35d1/conf/machine/ numaker-iot-ma35d16f90)

Choose what Image you want to build
Here we choose nvt-image-qt5 to build image
This step take about 3hrs first time (download and compile)
After compiling completed, you can see image at

•Update Yocto Project
•Update Linux
•Notice that, the command below will delete all Linux source code and download the newest source
code and compile.
•Clean the old Image and build the newer Image

Build Image by Yocto (3/3)
nuvoton@a24d9e06abe3:~/share/
yocto/build$ bitbake linux-ma35d1 –c cleanall && bitbake linux-

Nuvoton provide two method to program Image to evaluation board
1. Program image to SD card
2. Program image to any storage in evaluation board with NuWriter
First way is a quick way to evaluate application because of programming time less than second way
The power on setting could be referred to MA35D1 user manual

Leave the Docker container or create a new command window
Format your SD card first and search the SD card number
Copy the image to SD card
After copying, insert the SD card to evaluation board, switch power setting to SD Booting, and boot
