Getting Started with M64

Introduction

Overview Banana Pi BPI-M64

Overview: BPI-M64 respbian linux

Banana Pi BPI-M64 is a 64-bit quad-core mini single board computer. It features 2GB of RAM and 8GB eMMC. It also has onboard WiFi and BT. On the ports side, the BPI-M64 has 2 USB A 2.0 ports, 1 USB OTG port, 1 HDMI port, 1 audio jack, and lastly a DC power port. The processor is pin-to-pin comptialbe with R18, so it comes with two versions:M64 and M64-R18

Install Linux Image on M64

Prepare

 * Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System
 * Using your USB-Serial Connect debug console on M64

Download Image to SDcard

 1.You could download latest image from our forum
 
 2.Install bpi-tools on your system
 * apt-get install pv
 * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
 
 3.After you download the image, insert your TF card into your Ubuntu
 * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card.
 
 4.After step 3, then you can insert your TF card into M64, and press power button setup M64

Download Image to EMMC

 * Run your M64 with TF card
 * Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 * Plug your USB disk in M2U
 * After M64 recognise USB disk, execute "bpi-copy xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to install image on EMMC
 * Then power off M64, take TF card out, power on M64

Switch to LCD7 bootup

• The default release images are HDMI bootup type, you can switch to LCD bootup type after first boot.

 $ sudo bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m64/BPI-M64-LCD7-linux4.4-8k.img.gz
 $ reboot

Other development and test

GMAC

Use iperf3 to test gmac

1. On PC Terminal:

• Execute "iperf3 -s"

2. On M2U console:

• TCP test: "iperf3 -c serverIP"
• UDP test: "iperf3 -u -c serverIP"

Bluetooth

• Use bluetoothctl tool to operate BT
• Execute "bluetoothctl"
• If you don't know how to use bluetoothctl, type "help", you will see more commands
• Execute these commands:

WiFi on A64

WiFi Client

You have two ways to setup WiFi Client

1. Use commands to setup WiFi client

• ip link set wlan0 up
• iw dev wlan0 scan | grep SSID
• vim /etc/wpasupplicant/wpa_supplicant.conf

 network={    
 ssid="ssid"    
 psk="password"    
 priority=1 
 }

• wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
• dhclient wlan0

2. Use UI interface to setup WiFi Client

Ap Mode

1.Install hostapd and create hostapd configuration file hostapd.conf:

interface=wlan0
driver=nl80211
ssid=test
hw_mode=g
channel=1

2.Execute command："hostapd -d /<path>/hostapd.conf" If you meet problem like this：

Then, you could solve by following command：

• nmcli radio wifi off

• rfkill unblock 1
• rfkill unblock 2
• ifconfig wlan0 up
• hostapd -d hostapd.conf

Clear boot

• git clone https://github.com/BPI-SINOVOIP/BPI-files/tree/master/SD/100MB
• bpi-bootsel BPI-cleanboot-8k.img.gz /dev/sdX

GPIO Control

• To access a GPIO pin you first need to export it with

 echo XX > /sys/class/gpio/export

• with XX being the number of the desired pin. To obtain the correct number you have to calculate it from the pin name (like PH18)

 (position of letter in alphabet - 1) * 32 + pin number
  for PH18 this would be ( 8 - 1) * 32 + 18 = 224 + 18 = 242 (since 'h' is the 8th letter)

• echo "out/in" > /sys/class/gpio/gpio*NUMBER*/direction
• echo "0/1" > /sys/class/gpio/gpio*NUMBER*/value

Camara function

We use HDF5640 camara.

Guvcview

• Use your UI interface to operate camara
• Applications -> Sound & Video -> guvcview

Shell

• We also have built-in command in "/usr/local/bin" to test camara
• "./test_ov5640_image_mode.sh" to test picture taking function
• "./cameratest.sh" to test video recording function

IR function

• Execute "getevent"
• Use your IR device to send information to A64

RPi.GPIO

Install RPi.GPIO

• Execute "git clone https://github.com/BPI-SINOVOIP/RPi.GPIO"
• after clone the repo, cd RPi.GPIO
• Execute "sudo apt-get update"
• Execute "sudo apt-get install python-dev python3-dev"
• Execute "sudo python setup.py install" or "sudo python3 setup.py install" to install the module

Using RPi.GPIO

• cd /usr/local/bin
• Execute "./bpi_test_g40.py" to test RPi.GPIO

WringPi

• GitHub: https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git
• We also have built-in test command in "/usr/local/bin"

How to Update WiringPi

• Execute "bpi-update -c pkglist.conf"

• If your image is 32bit please do this command to install wring pi
• Execute "bpi-update -c bpi-pkg-bpi-wiringpi.conf"
• If your image is 64bit please do："bpi-update -c bpi-pkg-bpi-wiringpi-arm64.conf"

RGB 1602 LCD

• Execute "/usr/local/bin/bpi_test_lcd1602.sh"

0.96 Inch OLED Display

• Execute "/usr/local/bin/bpi_test_52pi.sh"

8x8 RGB LED Martix

• Firstly you need a GPIO Extend Board for 8x8 LED Martix

• Execute "/usr/local/bin/bpi_test_gpio40.sh"

File System

• read only system change to read & write mode: "mount -o remount,rw /"
