|
| |
| ==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
| |
|
| |
| [[Image:M2U_Sata.png]]
| |
|
| |
| * Sata接口接了硬盘后, 执行 "fdisk -l"
| |
| [[Image:M2U_Sata_fdisk_l.png]]
| |
|
| |
| * 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
| |
| [[Image:Sata_test.png]]
| |
|
| |
| ===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
| |
| [[Image:M2P_ADBD.png]]
| |
|
| |
| 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
| |
| [[Image:M2P_ADBD_Shell.png]]
| |
|
| |
| ===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"
| |
| [[Image:M2U_bootsel_lcd7.png]]
| |
|
| |
| ===触摸屏===
| |
|
| |
| ===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"
| |
| [[Image:M2U_Gmac_test.png]]
| |
|
| |
| ===蓝牙===
| |
| * 使用蓝牙工具来操作 BT
| |
| * 执行 "bluetoothctl"
| |
| * 如果你不知道如何使用 bluetoothctl, 输入 "help", 你能看到更多命令的用法
| |
| * 执行以下命令:
| |
|
| |

| |
|
| |
| ===WiFi M2U===
| |
| ====WiFi====
| |
| '''你有两种方式来启动 WiFi '''
| |
|
| |
| 1. 使用命令在创建WiFi客户端
| |
| * 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. 使用图形界面（GUI）来启动 WiFi Client
| |
|
| |
| ===清理 boot===
| |
| * git clone https://github.com/BPI-SINOVOIP/BPI-files/tree/master/SD/100MB
| |
| * bpi-bootsel BPI-cleanboot-8k.img.gz /dev/sdX
| |
|
| |
| ===摄像头===
| |
| 这里使用 HDF5640 摄像头.
| |
|
| |

| |
| ====Guvcview====
| |
| * 使用系统自带的Guvcview打开摄像头
| |
| * Applications -> Sound & Video -> guvcview
| |
| ====脚本方式打开====
| |
| * 我们已经集成了一些测试摄像头的命令在 "/usr/local/bin"
| |
| * "./test_ov5640_image_mode.sh" 可以测试拍照功能
| |
| * "./cameratest.sh" 可以测试摄像功能
| |
|
| |
| ===红外(IR)功能===
| |
| * 执行 "getevent"
| |
| * 使用你的IR设备向 M2U发送信息
| |
|
| |
| ===WringPi===
| |
| * GitHub: https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git
| |
| * 我们已经集成了相关的命令到 "/usr/local/bin"
| |
|
| |
| ====RGB 1602 LCD====
| |
| * 执行命令 "/usr/local/bin/bpi_test_lcd1602.sh"
| |
|
| |
| ====0.96 Inch OLED Display====
| |
| * 执行命令 "/usr/local/bin/bpi_test_52pi.sh"
| |
|
| |
| ====8x8 RGB LED Martix====
| |
| * 首先你需要一个8x8 LED Martix 的 GPIO 扩展板
| |
| [[Image: WringPi_LED_Martix_Extend_Board.png]]
| |
|
| |
| * 执行命令 "/usr/local/bin/bpi_test_gpio40.sh"
| |
|
| |
| ===文件系统===
| |
| * 只读文件系统改为可读可写: "mount -o remount,rw /"
| |
|
| |
| ===Install Qt5.7 & Qtcreator===
