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

进阶开发

如何编译 uboot & kernel

安装相关工具

• 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

复制代码

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

SATA

1. 加载Sata到 M2U

• Sata接口接了硬盘后, 执行 "fdisk -l"

• 然后 "mount /dev/sdx /mnt/xxx"

2. 如果你在挂接Sata的时候出现错误, 可以尝试用以下的命令:

• "fdisk /dev/sdx" 创建一个新分区, 设置分区个数和大小, 创建分区后, 输入 "wq" 保存和退出.
• "mkfs.ext2 /dev/sdx" 来格式化Sata
• "mount /dev/sdx /mnt/xxx"

3. 接上Sata后, 我们可以输入以下命令来测试Sata的性能:

• "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. 在 M2U 串口终端:

• 执行 "./adbd.sh", 然后执行 "ps -ax | grep adbd" 观察adbd是否启动

2. 在 PC 终端:

• 如果adbd成功启动, 插入 OTG-USB 接口到 M2U 和 PC( PC 运行 Ubuntu 系统)
• 执行 "adb devices" 来观察PC是否已经识别到 M2U OTG
• 如果已经识别到, 则执行 "adb shell" 则可以通过adb 来连接 M2U

LCD 5" & LCD 7"

• 执行 "bpi-bootsel", 然后你会看到一列boot文件列表
• 找到文件 "BPI_M2U_LCD7.img.gz"
• 然后执行 "bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_LCD7.img.gz"

GMAC

使用 iperf3 来测试 gmac

1. 在PC端:

• 执行 "iperf3 -s"

2. 在M2U串口端:

• TCP 测试: "iperf3 -c serverIP"
• UDP 测试: "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 /"
