基础开发

开发前准备

 * 准备一张容量不低于8Gb的TF卡, USB-Serial 串口线, 一台运行Ubuntu系统的PC机
 * 使用你的串口线去连接M2U的调试串口

烧录第一个Linux镜像到 M2U

 1.你可以从下面链接下载最近的镜像
 * http://forum.banana-pi.org/t/banana-pi-bpi-m2u-berry-new-image-release-raspbian-jessie-8-0-2018-5-24/5812 
 
 2.在你的Ubuntu系统电脑上安装bpi-tools, 执行以下命令即可安装：
 * apt-get install pv
 * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
 
 3.下载完镜像后, 插入TF卡到你的Ubuntu电脑中
 * 运行命令 "bpi-copy xxx.img /dev/sdx" 烧录镜像到你的TF卡中.
 
 4.烧录完成后, 把TF卡插到M2U中, 按住M2U的电源键启动M2U.

烧录第一个Linux镜像到 M2U EMMC

 * 首先烧录一个镜像到sd卡, 并从该sd卡启动M2U
 * 复制镜像 "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" 到你的U盘
 * 将U盘插到 M2U中
 * M2U识别到U盘后, 执行"bpi-copy xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" 安装镜像到 EMMC
 * 关机M2U, 取出sd卡, 从新上电M2U

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

Clone code

git clone: https://github.com/BPI-SINOVOIP/BPI-M2U-bsp.git
./build.sh

SATA

1. Mount SATA on M2U

After insert sata interface, execute "fdisk -l"

Then "mount /dev/sdx /mnt/xxx"

2. If you meet some errors when you mount SATA, try these following commands:

"fdisk /dev/sdx" to create new partition , set your partition numbers and size, after created partitions, input "wq" to save and quit.
"mkfs.ext2 /dev/sdx" to format the SATA
"mount /dev/sdx /mnt/xxx"

3. After you success to insert SATA, we could input following commands to test SATA interface:

"time dd if=/dev/xxx of=/dev/null bs=1M count=1000" to test read speed
"time dd if=/dev/zero of=/dev/sdx bs=1M count=1000" to test write speed

OTG

1. On M2U console:

Execute "./adbd.sh", then execute "ps -ax | grep adbd" to see if adbd is set up

2. On PC terminal:

If adbd was succeed to set up, insert OTG-USB interface to M2U and PC(with Ubuntu system)
Execute "adb devices" to see if PC has recognised M2U OTG
If yes, we could execute "adb shell" to connect M2U by adb now

LCD 5" & LCD 7"

Execute "bpi-bootsel", you'll see a list of boot files
Find "BPI_M2U_LCD7.img.gz"
Then execute "bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_LCD7.img.gz"

Touch screen

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 M2U

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 -B -dd -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
dhclient wlan0

2. Use UI interface to setup WiFi Client

Clear boot

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

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 M2U

WringPi

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

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 /"

Install Qt5.7 & Qtcreator

1.Prepare a 32Gb TF card

2.Use GParted to resize root point '/' as 32Gb

3.apt-get install libxcb*

4.download qt5.7

5.make & make install

6.apt-get install qtcreator

7.Config qtcreator
