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.
 
 

将镜像烧录到eMMC

 1.通过SD卡启动BPI-M1+
 2.将镜像文件拷贝到U盘中，并将U盘插到M1+USB口
 3.挂载U盘，将镜像文件写入eMMC中

 * 通过bpi-tools烧录
 curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools%7Csudo -E bash
 mount /dev/sda1 /mnt
 bpi-copy /mnt/xxx_M1+_xxx.img.zip /dev/mmcblk0

 * 通过dd命令烧录
 mount /dev/sda1 /mnt
 unzip -p xxx_M1+_xxx.img.zip |pv| dd of=/dev/mmcblk0 bs=10M status=noxfer

 写入完成后关机，取出SD卡并重新启动M1+

进阶开发

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

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 !
