开发
基础开发
烧录第一个Linux镜像到M1+
1.准备UART debug串口线和终端工具，如MobaXter
2.在官网中下载最新的M1镜像
* http://forum.banana-pi.org/t/bananapi-m1-m1p-r1-new-image-android-and-ubuntu-sever-release-2018-07-28/6357
3.准备一张不低于8GB的SD卡，读卡器，将读卡器插到电脑上。
4.下载SD Card Formmater，打开并格式化SD卡。
5.下载BalenaEtcher烧录工具，将镜像烧录到SD卡上。
6.取出SD卡插到BPI-M1卡槽，启动BPI-M1。
烧录第一个Android镜像到M1+
1.首先从论坛上下载最近的镜像. Ex:http://forum.banana-pi.org/t/bananapi-m1-m1p-r1-new-image-android-and-ubuntu-sever-release-2018-07-28/6357 2.准备一张容量不低于8Gb的TF卡, 然后插到你PC上的USB接口中. 3.下载烧录工具 PhoenixCard.exe.
- Download PhoenixCard: https://pan.baidu.com/s/18Fo_JhYY02gmxtFw2Ps3rQ
4.使用 "PhoenixCard.exe" 来烧录Android镜像到TF卡上.

SATA 接口
1. 挂载 SATA 到 M1P
- 将硬盘接到SATA接口后, 执行命令"fdisk -l"
- 然后执行命令 "mount /dev/sdx /mnt/xxx"
2. 如果你在挂载SATA的过程中遇到一些错误, 你可以尝试以下步骤来修复：
- "fdisk /dev/sdx" 来创建一个新的分区, 设置分区号和大小, 创建分区之后, 输入 "wq" 来保存退出.
- "mkfs.ext2 /dev/sdx" 来格式化 SATA
- "mount /dev/sdx /mnt/xxx"
3. 挂载SATA成功后, 可以执行以下命令来测试SATA接口的性能：
- "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
触摸屏
GMAC
使用 iperf3 来测试 gmac
1. 在 PC 终端启动Server：
- 执行命令 "iperf3 -s"
2. 在开发板端启动Client：
- 测试 TCP: "iperf3 -c serverIP"
- 测试 UDP: "iperf3 -u -c serverIP"
WiFi on M1P
WiFi Client
这里提供两种方法来开启WiFi
1. 使用命令行来开启WiFi 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. 使用图形界面来开启WiFi
2. Use UI interface to setup WiFi Client
清除 boot
1. 执行以下命令来清除boot git clone https://github.com/BPI-SINOVOIP/BPI-files/tree/master/SD/100MB bpi-bootsel BPI-cleanboot-8k.img.gz /dev/sdX
红外功能
- 执行命令 "getevent"
- 使用红外控制器发送数据到 M1P
RPi.GPIO
安装 RPi.GPIO
执行命令 "git clone https://github.com/BPI-SINOVOIP/RPi.GPIO" 克隆代码后, 进入到 "cd RPi,GPIO" 执行命令 "sudo apt-get update" 执行命令 "sudo apt-get install python-dev python3-dev" 执行命令 "sudo python setup.py install" or "sudo python3 setup.py install" to install the module
使用 RPi.GPIO
- cd /usr/local/bin
- 执行命令 "./bpi_test_g40.py" 可以测试Rpi.GPIO
WringPi
- GitHub: https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git
- 我们提供了集成的命令在 "/usr/local/bin" 中
RGB 1602 LCD
- 执行命令 "/usr/local/bin/bpi_test_lcd1602.sh"
8x8 RGB LED Martix
- 首先你需要一个8x8 LED Martix 的 GPIO 扩展板
- 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 /"
安装 QT
- sudo apt-get install build-essential
- sudo apt-get install libgl1-mesa-dev
- sudo apt-get install libglu1-mesa-dev
- sudo apt-get install freeglut3-dev
- sudo apt-get install cmake
- sudo apt-get install qt5-default qtcreator
A20 CAN Bus
移植can4linux 到 BananaPi, CAN 模块在 A20 硬件手册里面描述. can4linux 基于字符型的linux驱动并且早已经应用于Freescale FlexCAN 中(the i.MX series of micro controllers) or Xiliny Zynq.
关于A20的CAN总线这里有更多的描述: https://dl.linux-sunxi.org/A20/CAN%20Bus1.pdf
这里有如何在BananaPi上使用 CAN BUS 的说明：
Thank selqcir share this example:
- Download and install "bananian-1501.img" into 8 GB SDCard.
- Expand the root file system using "bananian-config"
- Install missing package:
apt-get install git apt-get update apt-get upgrade reboot
- Get last bananian available, and continu to install missing package:
git clone https://github.com/Bananian/linux-bananapi apt-get install build-essential u-boot-tools uboot-mkimage apt-get install libusb-1.0-0 libusb-1.0-0-dev git wget fakeroot kernel-package zlib1g-dev libncurses5-dev apt-get install subversion
- Build kernel:
cd linux-bananapi make menuconfig
- Exit without saving when menu appears
zcat /proc/config.gz > /root/linux-bananapi/.config make uImage modules make INSTALL_MOD_PATH=output modules_install
- At this step, kernel should be compiled and "Module.symvers" should be available
- Then rename modules and firmware provide by Bananian, and replace by the new one.
mv /lib/modules /lib/modules.old mv /lib/firmware /lib/firmware.old mv /root/linux-bananapi/output/lib/modules /lib/modules mv /root/linux-bananapi/output/lib/firmware /lib/firmware
- Same for uImage:
mount /dev/mmcblk0p1 /mnt cd /mnt mv uImage uImage.old mv /root/linux-bananapi/arch/arm/boot/uImage /mnt reboot
- Create link for further build:
cd /lib/modules/3.4.104/ ln -s /root/linux-bananapi build cd ~
- Get Can4Linux and build it:
svn checkout https://svn.code.sf.net/p/can4linux/code/trunk can4linux-code cd /root/can4linux-code/can4linux/ make TARGET=BANANAPI
- Install module for each startup of the board:
insmod can4linux.ko cp can4linux.ko /lib/modules/3.4.104/kernel/net/can/ depmod -A -v modprobe -v can4linux echo "" >> /etc/modules ; echo "can4linux" >> /etc/modules reboot
- Build CAN example
apt-get install swig apt-get install python-dev cd can4linux-code/can4linux-examples/
- Update CAN speed and device in file "pyCan-example.py"
# setting the device number device = 0 defaultBaudrate = '250'
- Connect CAN transceiver and CAN bus, and check with for example:
python pyCan-example.py
That's all
With this method, kernel version is "Linux bananapi 3.4.104" instead of "Linux bananapi 3.4.104+", because i was unable to find same sources than Bananian 15-01 , but CAN bus work !
