4. SDK Download And Compile

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

4.1 SDK Envirment Prepare

Compilation environment: Centos/Ubuntu Openwrt’s compilation tool is automatically generated by SDK built

apt install build-essential

4.1 SDK Download

Get the source code from Dusun FTP server uncompress it under your work directory. For example:

mkdir -p ~/workdir/dsgw081
tar zxvf DSGW-081_sdk_AV1.0.0.12.tar.gz -C /workdir/dsgw081
cd ~/workdir/dsgw081

4.3 SDK Compile

cd ~/workdir/dsgw081
./build.sh

4.4 SDK Output

  • zImage is the Kernel

  • imx6ull-14x14-emmc-4.3-480x272-c.dtb is the dtb file

  • modules.tar.bz2 is kernel module file

  • fs.img the root filesystem

4.5 Modify Default fs.img

4.5.1 filesystem image

./dl/arm32-debian-11-dsgw081.img

4.5.2 cp a new image and mount it to a tmp directory

cp ./dl/arm32-debian-11-dsgw081.img ./src/arm32-debian-11-dsgw081.img
mkdir -p ./src/tmp/
mount ./src/arm32-debian-11-dsgw081.img ./src/tmp/

4.5.3 chmod to the tmp directory

this need install qemu-arm-static

apt-get install qemu-arm-static

sudo LC_ALL=C LANGUAGE=C LANG=C chroot ./src/tmp/

if you chroot success, you can edit the image follow by 4.5.4

4.5.4 add some packet or bin files to the new root environment

  • install new packet
apt-get update;
apt-get install i2c-tools
  • compile myself c program
echo "int main(int argc ,char *argv[]) {return 0;}" > ~/main.c
gcc ~/main.c -o ~/main

9. Application Layer Development

9.1 Led

This board has three leds can be controlled by software, they are pwrled, zigbee, errled, led4

pwdled - indicate the system power on, it will blink when system startup, and hold on when running. zigbee - indicate the zigbee/zwave has rf data in. errled - indicate the mqtt diconnect or connectted to the the mqtt server. led4 - now not used.

9.1.1 on led

echo none > /sys/class/leds/pwrled/trigger
echo 1 > /sys/class/leds/pwrled/brightness

9.1.2 off led

echo none > /sys/class/leds/pwrled/trigger
echo 0 > /sys/class/leds/pwrled/brightness
echo timer > /sys/class/leds/pwrled/trigger
echo 500 > /sys/class/leds/pwrled/delay_on
echo 500 > /sys/class/leds/pwrled/delay_off

9.2 Button

This board has one button can used by software, when pressed, the system will auto call the button script in the /etc/rc.button/BTN1

here are two incomming parameters

  • SEEN: this is the time, unit seconds

  • ACTION: this is the action, it will we pressed or release

see the example has one function in the button script - firts is the long pressed 3 seconds open zigbee pair.

root@DSGW-081:~# cat /etc/rc.button/BTN_1 
\#!/bin/sh

\#. /lib/functions.sh
\#. /lib/functions/leds.sh

if [ "${ACTION}" = "pressed" ]; then
touch /tmp/BTN_0_pressed
touch /tmp/btn1
else
rm -f /tmp/BTN_0_pressed
fi

if [ -f /tmp/dusun_upgrade ] ; then
exit 0
fi

[ ! "${ACTION}" = "released" ] && {
exit 0
}

led_off() {
echo none > //sys/class/leds/$1/trigger
echo 0 > /sys/class/leds/$1/brightness
}

led_timer() {
echo timer > /sys/class/leds/$1/trigger
echo $2 > /sys/class/leds/$1/delay_on
echo $3 > /sys/class/leds/$1/delay_off
}


[ "$SEEN" -ge 3 ] && {
logger "Zigbee pairing"
ubus send DS.GREENPOWER '{"cmd" : "start_comission"}'

logger "$BUTTON pressed for $SEEN seconds : Permit Join For Zigbee3.0/ZWave"
/usr/bin/alink_ucmd.sh permit 1
/usr/bin/dusun_ucmd.sh permit 1
exit 0
}

9.3 Ethernet

this gateway has one ehternet port - wan port eth1

see the config

root@DSGW-081:~# cat /etc/network/interfaces
\# interfaces(5) file used by ifup(8) and ifdown(8)
\# Include files from /etc/network/interfaces.d:

auto eth1
iface eth1 inet dhcp


auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant.conf
metric 1

9.4 wifi

This gateway only have one 2.4 radio(rtl8821cs), when startup, it will auto start as sta mode.

see the config:

root@DSGW-081:~# cat /etc/network/interfaces
...
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant.conf
metric 1

9.5 Zigbee

9.7 LTE

This Gateway Has a LTE Module BG96 We use the pppd to dial and manage the bg96. here is some config and steps about the lte module

  • the apn config
root@DSGW-081:~# cat /etc/config/ppp

config 'ppp' 'ppp'
option 'apn' 'em'
option 'username' '111'
option 'password' '1122'
  • pppd dial scripts

-rwxr-xr-x 1 root root 163 Feb 27 2020 /etc/ppp/peers/mo_3gmodule.dial
  • do the pppd call in the foreground
  1. stop the demo program.
/etc/init.d/done stop; /etc/init.d/dial stop;
  1. modify the pppd to debug mode
root@DSGW-081:~# cat /etc/ppp/options
debug // remove #, open the debug mode
nodetach // add this
#logfile /dev/null // comment this line
noipdefault
  1. open the lte module
echo 0 > /sys/class/leds/ltepwr/brightness
echo 0 > /sys/class/leds/lterst/brightness

9.8 Can

this board has two can interace named can0

we can use loopback mode to test it

  • set up can and start receive mode
ifconfig can0 down;
ip link set can0 type can bitrate 500000 loopback on;
ifconfig can0 up;
candump can0
  • clone anther ssh send data
cansend can0 5A1#11.22.33.44.55.66.77.88

9.9 Dout

we can echo ‘0’ or ‘1’ to a file to control the dout1 and dout2 to on or off.

  • on
echo 1 > /sys/class/leds/do01/brightness
  • off
echo 0 > /sys/class/leds/do01/brightness

9.10 Passive In

the passive in will auto generate a event to the /dev/input/by-path/platform-gpio_keys\@0-event

9.11 Active in

here is two active input interfaces on the board(iio:device/iio:device1).

we can easy get the voltage input

local val=`cat /sys/bus/iio/devices/iio\:device1/in_voltage_raw`
val=$((val*33*11/2560))
echo $val V

9.12 Analog in

here is two analog input interfaces on the board(hwmon0/hwmon1).iio:device/iio:device1

we can easy get the voltage input.

local val=`cat /sys/class/hwmon/hwmon0/in1_input`
val=$((val*33*11/2560))
echo $val

9.13 RS232

here is a 232 port on the board

we can use minicom or other user serial tool to test it

the port is /dev/ttymxc3

9.14 RS485

here is a 485 port on the board

we can use minicom or other user serial tool to test it

the port is /dev/ttymxc4
