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

If you used VMware provide by Nuvoton, you have already created a MA35D1 Docker container

Software Tool

。Programming –NuWriter

Environment Setup

•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

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"

The Yocto Project is an open source collaboration project that helps developers create custom Linux-

based systems regardless of the hardware architecture

MA35D1 Yocto includes the following Metadata

。Meta-ma35d1

。Meta-qt5

。Meta-virtualization

。Meta-Pocky

•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)

•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

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

Login password: root
