Introduction To Software

Preparatory Work

Materials Required

Aurora100 or Aurora200
Internet network
Internet cable
4GB (or more memory) SD card and SD card reader
PC (Windows10)
USB To Uart Adapter (optional)
24V/2A DC interface adapter
Multimeter
Especial Speaker x 1 (Aurora100) or Especial Speaker x 2 (Aurora200)
Especial Mic

Uptdate firmware

Step 1. Select the firmware to download and this firmware both Aurora 100 and Aurora 200 all be used:

Step 2. Connect an SD card to a PC or MAC with an SD card reader, an SD card with more than 4G memory is required.
Step 3. Click here to download Etcher, then use the Etcher to write the *.img.xz file directly to the SD card. Or extract the *.img.xz file into a *.img file, and then burn it to an SD card using another mirror write tool.

we can get below the picture when the etcher burns successful.

Step 4. After writing the image to the SD card, insert the SD card into Aurora.

For Aurora 100

For Aurora 200

Step 5. Connect Aurora to a computer by using USB To Uart Adapter.the hardware connection as below.

|Aurora|USB To Uart Adapter| |:----:|:------:| |TX|RX| |RX|TX| |GND|GND|

For Aurora 100

For Aurora 200

Step 6. Connect RST to GND at stm8 to stop stm8 power-manager code.

we can skip this step if use the newest firmware for stm8

For Aurora 100

For Aurora 200

the system will reboot repeatedly if our firmware does not have mpu-power-manager.service.and there does not exist mpu-power-manager.service in firmware downloaded from BeagleBoard Site. So we have to connect RST to GND at stm8 to stop the power management by STM8. we will install the mpu-power-manager.service at subsequent steps.

Step 7. Use PUTTY, select Serial protocol, fill in the correct COM port of Aurora, 115200 baud, 8Bits, Parity None, Stop Bits 1, Flow Control None.

Step 8. Use a 24V Power adapter to power the Aurora board. and you can see the LED power on. Do not take out the SD card during writing.
Step 9. The login user name is debian, and password is temppwd.

Step 10. Edit /boot/uEnv.txt then reboot to start eMMC boot.

sudo sh -c "echo cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-\
flasher-v3.sh >> /boot/uEnv.txt"
sudo reboot

it will take some time for updating firmware.please wait with patience.

You have to power off the board and unplug sd card when you terminal show this message.and the script will updating firmware repeatedly if we does not power off.Meanwhile,the four USER-LED will stop blinking and turn off if the update successful.

Step 11. Unplug sd card then power on.

If you boot at emmc , the terminal will print /dev/mmcblk1p1.

Step 12. Connect Internet cable to Ethernet interface . if the Green LED blinking and Yello LED lighting indicate that the network works well.we can get as below information about the eth0 at Aurora if we type ifconfig cmd.

ifconfig

the ip addr maybe different for this picture depending on your router.

Step 13. Internet test

ping -c 5 china.com

if the terminal print like this indicates the network has been connecting to the Internet.if we can not get the Internet maybe need to check your network environment.

Devices Usage

Env install

Step 1. git clone the test code.

cd ~
git clone --depth 1 https://github.com/Hansen0314/aurora_test.git

the aurora_test have below content.

aurora test code	test aim
gpio	+12VS Input Relay LED state
power-service	power manager
voice_card	Voice card

Step 2. Install the gpio to control the gpio of Aurora.

sudo cp ~/aurora_test/gpio /bin/

Step 3. Install the power-service that communicate with stm8 to enable mpu-power-manager.service.

cd ~/aurora_test/power-service
sudo ./install.sh

and power-service folder has below file:

1.STM8Firmware/power_manager.hex: firmware for stm8 and how to update the firmware to stm8 you can view Update STM8 firmware

2.install. sh: mpu-power-daemon.service install script.

3.mpu-power-daemon.service: service config file for AM3358.

4.power_manager.sh: power manager script for AM3358.the more information you can access power-manager.

you can disconnect GND to RST at stm8 for now.

Step 4. Disable cloud9 service when next power on.

sudo systemctl disable cloud9.socket

if everything well we can get information as below .

debian@beaglebone:~$ sudo systemctl disable cloud9.socket
Removed /etc/systemd/system/sockets.target.wants/cloud9.socket.

Step 5. Install voice card to enable speaker and mic then reboot.

sudo cp ~/aurora_test/BB-BONE-AUDI-02-00A0.dtbo /lib/firmware
sudo sh -c "echo uboot_overlay_addr0=/lib/firmware/BB-BONE-AUDI-02-\
00A0.dtbo >> /boot/uEnv.txt"
cd ~/aurora_test/voice_card
sudo cp asound.state /var/lib/alsa/
sudo cp asound.conf /etc/
sudo reboot

and voice_card folder has below file:

1.asound.conf: config ALSA.set the LEFT_LOP as output.and set LINE2R as input. more information you can access alsa.

2.asound.state: config voice card settings.make aplay and arecord work with the mono mode at default.
more information you can access alsa.

3.open_Amplifier.sh: open Amplifier.

4.power_on_voice.sh: power on voice then record and play.more information you can access Voice card of devices-usage

If the terminal prints no error go to next step.

+12VS

we can use this cmd to make +12VS power on.

gpio set 22

and the pin's location you can view the Extern-Interface-pinout.You can get 12v at +12VS by using a multimeter.

we can use this cmd to make +12VS power off.

For Aurora200

if you use aurora 100 we can use this cmd to test it.

cd ~/aurora_test/voice_card
sudo alsactl restore 0 -f asound.state
./open_Amplifier.sh 1
arecord -f dat -D hw:0 test.wav
aplay test.wav

if you use aurora 200 we can use this cmd to test it.

cd ~/aurora_test/voice_card
sudo alsactl restore 0 -f asound.state
./open_Amplifier.sh 1 #the one speaker
#./open_Amplifier.sh 2 #the other speaker
arecord -f dat -D hw:0 test.wav
aplay test.wav

the codec detail as follow:

sample rate	channels	Sample formats
8k 32k 44.1k 48k 96k	2	S16_LE S24_LE S32_LE S24_3LE

you can hear your speech form the Speaker if you speak to the mic.and you can adjust the knob to modify the sound volume for hardware side.the software also supports adjust the sound volume by using alsamixer.

sudo alsamixer

The asound.conf and asound.state that you can found by accessing github.'

this is MIC power on/off cmd .

amixer -c B cset numid=34,iface=MIXER,name='PGA Capture Switch' on 
//Power on Mic
amixer -c B cset numid=34,iface=MIXER,name='PGA Capture Switch' off 
//Power off Mic

DDR3 speed test

Step 1. install speed test tool

sudo apt update
sudo apt install -y mbw

if update failed we can use as below cmd to install ''mbw"

cd ~
wget http://ftp.cn.debian.org/debian/pool/main/m/mbw/mbw_1.2.2-1+\
b1_armhf.deb
sudo dpkg -i mbw_1.2.2-1+b1_armhf.deb

Step 2. test speed

mbw -q 100

we can get this message

EMMC speed test

Step 1. clear caches

sudo sh -c "echo 3 > /proc/sys/vm/drop_caches"

Step 2. test speed

time sudo dd if=/dev/mmcblk1 of=/dev/null bs=128k count=8192

we can get this message

8192+0 records in
8192+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 26.4425 s, 40.6 MB/s

Power manager

Power manager have two-part on the one hand is stm8 and on the other hand, is AM3358.we have to use this cmd to enable stm8's power manager at AM3358 after is enabled the Aurora.and the location of stm8 and AM3358 we can view hardware-overview.

gpio set 45

and this is content of power manager.The stm8 will send a message to AM3358 1.5min / time. if AM3358 cannot feedback to stm8, the stm8 will restart the AM3358.There exist a feedback code in our GitHub for AM3358.

If the power manager power on at stm8, at the same time the AM3358's power manager has to enable. how to enable it we can view Env install's step4.

We need to generate the falling edge level at AM3358 if you want to disable the stm8's power manager.
