Introduction

This Quick Start Guide explains the basics: – how to connect and set up your target on the network – how to install the SDK – how to modify and 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 DSOM- 080M Module.

Baseboard Information

This section describes the baseboard’s basic resource infomation and interfaces.
2.1 Basic information

• 1 CORE CPU(MT7628AN)
• 1 led
• 1 button
• 1 wan(10/100M)
• 4 lan(10/100M)
• 2 uart

2.2 Interface

Debug Setup

This section describes how to connect the board into your host computer and network to debug for development.

3.1 Power

• Make sure that the power adapter is 5V/2A.

• 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.

• Connect the output plug of the power supply to the gateway

3.2 Wire Connect
Connect gateway to a router for login

3.3 Debug Uart Connect

• Before you set up your development test bed, please connect the PCB serial port to your develop PC via USB-to-serial bridge.

USB-to-serial bridge. Serial port setting:
Baud rate: 57600
Bits: 8
Stop Bits: 1
Hardware flow control: None

SDK Download And Compile

This section describes how to download the sdk and compile it.

4.1 SDK Envirment Prepare
Compilation environment: Ubuntu20.4 Yocto compilation tool is automatically generated by SDK built, no additional installation is required
4.2 SDK Download
Get the source code from Dusun FTP server uncompress it under your work directory. For example: mkdir -p ~/workdir/dsom080m
tar zxvf DSOM-080M_sdk_AV1.0.0.0.tar.gz -C /workdir/dsom080m cd ~/workdir/dsom080m

4.3 SDK Compile

• run build.sh
  cd ~/workdir/dsom060r ./build.sh

4.4 SDK Output

• uboot.bin is the uboot

Firmware Program And Program

5.1 Firmware Upgrade
5.1.2 Uboot Web Upgrade

• Press n when power on or reset use serial login

• Connect the gateway and computer directly with a network cable, and set the IP address of the computer to 192.168.0.222,
  

• Enter 192.168.0.250 in the browser to open the uboot upgrade page
  

5.1.3 System Command Upgrade

• use scp or winscp tool to put the fw.bin to the board’s tmp scp openwrt-ramips-mt7628-mt7628-squashfs-sysupgrade.bin@192.168.xxx.xxx:/tmp/
• run sysupgrade command to upgrade the firmware sysupgrade -n -F openwrt-ramips-mt7628-mt7628-squashfs-sysupgrade.bin

Gateway Login

6.1 Login Through Debug Uart

• connect uart serial tool to the board’s debug uart port

• config the serial tools’s uart config
  

• power on the gateway
  

6.2 Login Through Network(SSH)

• config the ssh connection parameters
  

• set the password to root use serial login or web page serial : root@OpenWrt:/# passwd root
  Changing password for root New password:
  Bad password: too short
  Retype password:
  Password for root changed by root web page

Application Layer Development

7.1 Led
This board has one leds can be controlled by software, it connect to the WIFI_LED(GPIO#44)

• switch pin to gpio mode reg w 64 1

• on led
  gpio l 44 4000 0 1 0 4000

• off led
  gpio l 44 0 4000 0 1 4000

• blink led
  gpio l 44 1 1 4000 0 4000

7.2 Button
This board has three buttons can used by software, we can use gpio command to read it

• switch to gpio mode reg w 60 0x55144051

• read wdt rst value before pressed root@OpenWrt:/# gpio r
  gpio 95~64 = 0x0
  gpio 63~32 = 0x77cd
  gpio 31~00 = 0x80002400
