Introduction

• This Quick Start Guide explains the basics: how to connect and set up your target on the network; how to install the SDK; and how to build the firmware images.
• The Linux Software Developer’s Kit (SDK) is an embedded hardware and software suite that enables Linux developers to create applications on Dusun’s DSGW-290 gateway.
• Base on the 4.19.232 Linux kernel, and leveraging existing open source software, the SDK simplifies the process of adding custom applications. Device drivers, GNU toolchain, Pre-defined configuration profiles, and sample applications are all in included.

Interface

Target Setup

This section describes how to connect the gateway into your host computer and network.

Connecting a gateway – Power

1. Make sure that the power adapter is 12V/3A.
2. Select the appropriate power plug adaptor for your geographical location. Insert it into the slot on the Universal Power Supply; then plug the power supply into an outlet.
3. Connect the output plug of the power supply to the gateway

Connecting a gateway – Network interface

1. Connect one end of the network cable to the network port on the laptop or desktop
2. Connect the other end of network cable to the network port on the gateway.
3. SSH login gateway ip address，username is root passwd is root.

Compile the Environment to Build

Please use ubuntu 18.04 .iso image to setup your build environment. You can use a virtual machine or a physical PC to install ubuntu 18.04

Virtual Machine
It is recommended that novice users use virtual machines, install ubuntu 18.04 to the virtual machine, and leave enough disk space (at least 100G) for the virtual machine.

Ubuntu PC Compile the Environment to Build
The use of physical machine compilation users can use a ubuntu PC.

SDK Acquisition and Preparation

Download the source code from the Dusun FTP
The source package name will be rk356x_linux-*.tar.gz, get it from Dusun FTP.

Code Compression Package Check
The next step can be taken only after generating the MD5 value of the source compression package and comparing the MD5 value of the MD5 .txt text to confirm that the MD5 value is the same, and if the MD5 value is not the same, the energy code pack is damaged, please download it again.

The Source Compression Package is Unzipped
Copy the source code to the corresponding directory and unzip the source code compression package.

Code Compilation

Getting started, global Compilation
Prepare the Root File System base
This section is for building ubuntu or debian file system. If you want to build the buildroot file system, skip this section.
Compile Ubuntu
Download the root file system compression package ubuntu.tar.gz
The Root file system compresses the package directory：
Unzip the compression package

Copy the root file system to the specified path

Change the build config

Compile Debian
Download the root file system compression package debian.tar.gz Unzip the compression package

Copy the root file system to the specified path

Change the bulidconfig

Start Compiling
Build a complete directory of firmware files: rockdev/pack/AIO- 3568J_Rk356x.img and other separate images, AIO-3568J_Rk356x.img includes all firmware for full upgrade.

• $ ./build.sh

The build will take a long time, please wait patiently.
After AIO-3568J_Rk356x*.img is built, burn it to the board according to chapter 7.

Run The Image on the board
Connect the RK3568 board serial port to the PC via a USB to UART Bridge.
Use Putty or other Terminal software as your console tool,
SERIAL CONSOLE SETTINGS:

• 115200/8N1
• Baud: 115200
• Data Bits: 8
• Parity Bit: No
• Stop Bit: 1

Power UP the board, you can see the boot log on console:

There is no default password for system login.

Compiled Each Image Part Separately
The build system and the image structure

• The AIO-3568J_Rk356x*.img is composed of several parts. Main parts are uboot.img, boot.img, recovery.img, rootfs.img. uboot.img contains bootloader uboot boot.img contains the device tree .dtb image, Linux kernel image recovery.img:
• The system can boot up to recovery mode, recovery.img is the rootfs used in recovery mode. rootfs.img: The normal rootfs image. In normal mode, system boot and mount this rootfs image.
• You may need to build the images separately, especially when you focus on single module (e.g. uboot or kernel driver) development. Then you can build only that part of image and update that partition in flash.

Build Uboot only

• $ ./build.sh uboot

Build Linux Kernel Only

• $ ./build.sh kernel

Build Recovery File System Only

• $ ./build.sh recovery

Build File System Only

• $ ./build.sh rootfs

Final Image Packaging

• $ ./build.sh updateimg

This command making rockdev/*.img scatter firmware packaging builds in the directory update.img

Wireless development

(Zigbee, Z-Wave, BLE, LoRaWAN, WIFI,Thread,SUB-G,LTE)
Please build a debian system to do the following steps. The code will be compiled on the board, not on host.

Zigbee
Zigbee interface is /dev/ttyS3.
Exec command: AmberGwZ3 -n1 -p /dev/ttyS3 -b115200 -d

Z-Wave
Z-Wave interface is /dev/ttyS4 .

Exec command: zwdevd -b115200 -d/dev/ttyS4

Z-Wave region
If for default Dusun built, Z-Wave frequency can be configured in vi /etc/config/dusun/zwdev/region
Default is 0x00: EU

• 0x01 – US
• 0x05 – India
• 0x20 – Japan
• 0x02 – ANZ
• 0x06 – Israel
• 0x21 – Korea
• 0x03 – HK
• 0x07 – Russia
• 0x04 – Malaysia
• 0x08 – China

BLE
BLE interface is /dev/ttyS7.
Exec command: bul -d /dev/ttyS7 -b115200

LoRaWAN
Choose the correct interface for LoRaWAN, for example /dev/spidev1.0. The configuration file for it is in /root/sx1302_hal/packet_forwarder/global_conf.json.

Thread
Note:

1. Please build a debian system to do the following steps. The code will be compiled on the board, not on host.
2. The thread here is based on the OpenThread .

What you need to prepare
If you want to run with thread-network correctly, the following steps should be care:

1. a thread module on the board which has been flashed the OT-RCP firmware;
2. build OTBR and its operating environment; 8.5.2 Build OT-RCP

The OT-RCP is a application running on the thread module, which may contain bootloader.
How to build OT-RCP based on the module brand and model you choose, please refer to their documents.
Burning the OT-RCP and ensure that it can run normally.

Build OTBR

Clone source code :

• cd you_thread_path/ot-br-posix

• git init

• git clone https://github.com/openthread/ot-br-posix

If need support web:

• cd you_thread_pathot-br-posix

• WEB_GUI=1 ./script/bootstrap

Build (INFRA_IF_NAME is based on your Ethernet network on your system, it may be eth1 or other;
and if you are using wifi-network, INFRA_IF_NAME may be wlan0 or other; set WEB_GUI value to 1 if you need web, or 0):

• INFRA_IF_NAME=eth0 WEB_GUI=1 ./script/setup

Building success:
You will find Executable program:

• otbr-agent : you_thread_path/ot-br-posix/build/otbr/src/agent/
• otbr-web(If you have enabled web): you_thread_path/ot-br-posix/build/otbr/src/web/
• ot-ctl: you_thread_path/ot-br-posix/build/otbr/third_party/openthread/repo/src/posix/

Configure otbr
The default path of configure file : /etc/default/otbr-agent

The content is like:

• OTBR_AGENT_OPTS=”-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyACM0 trel://OTBR_INFRA_IF_NAME” OTBR_NO_AUTO_ATTACH=0

The eth0 is same to before.
The /dev/ttyACM0 is the device name of your thread module which has burned OT- RCP firmware. So you have to change to the device name of your own equipment.
Note: After modifying, reboot your gateway !!!
The otbr-agent will connect OT-RCP automatically after rebooting.

Start/Stop/Status otbr

Log

Debug thread-network with ot-ctl

Other command about ot-ctl, you can input help to learn.

WIFI
WIFI is used by desktop system.

SUB-G
SUB-G interface is /dev/ttyS9.
Exec command: microcom -s 115200 -p /dev/ttyS9

LTE
LTE used by ModemManager.

• Print general mmcli help message: mmcli –help
• ModemManager normally listen, probes and detects cellular devices automatically when operating correctly but a forced scan can be triggered with command: mmcli –scan-modems << successfully requested to scan devices
• To list detected cellular devices use command: mmcli –list-modems << /org/freedesktop/ModemManager1/Modem/0 [Sierra Wireless, Incorporated]
• Here ModemManager have detected a Sierra Wireless cellular device and it has here been given the the identifier number 0 by ModemManager.
• To acquire more device information and status use the –modem command and identifier value. mmcli –modem=0
