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

Development

Basic Development

Prepare to develop

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

Load your first image on M64

 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

Load your first image on M64 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

Advanced Development

Update your image

  * After built bsp code, you could find "SD" directory in project, "cd SD" you could find the generated bootloader, rootfs
  * execute “bpi-tools”, to update your bpi tools;
  * execute “bpi-update -c bpi-m64.conf -d /dev/sdX”, to download new driver to update your image
  * execute “file *.tgz”, to check download files’ type is compressed data
  * execute “bpi-bootsel”, you will see the bootloader path, “/usr/lib/u-boot/bananapi/bpi-m64/u-boot-with-dtb-bpi-m64-720P-8k.img.gz”
  * execute “bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m64/u-boot-with-dtb-bpi-m64-720P-8k.img.gz”, to update your bootloader
  * reboot

How to build uboot & kernel

Install tools

• apt-get udpate
• apt-get install gcc-arm-linux-gnueabihf u-boot-tools
• apt-get install pv
• curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash

Touch screen

LCD 7"

• Execute "bpi-bootsel", you'll see a list of boot files
• Find "BPI_A64_LCD7.img.gz"
• Then execute "bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m64/u-boot-with-dtb-bpi-m64-lcd7-8k.img.gz"

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:

Solve

• 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 /"
