开发
Linux
准备
- 1. Linux镜像支持SD卡或EMMC启动,但您应该首先阅读[Boot_Sequence启动顺序]。
- 2. 建议使用A1级别的SD卡,至少8GB。
- 3. 如果要从SD卡启动,确保可启动的EMMC已经格式化。
- 4. 如果要从EMMC启动并将SD卡用作存储,确保SD卡已经格式化,没有刷入Linux镜像。
- 5. 下载最新的[Linux镜像],并确认md5校验和正确。
- 6. 默认登录用户名:pi/bananapi或root/bananapi。
- 7. Wiki指南仅适用于[bananapi 4.9 bsp ubuntu/debian镜像]。
将镜像安装到SD卡
- 1. 在Windows、Linux和MacOS上使用Balena Etcher安装镜像。
- Balena Etcher 是Balena提供的开源GUI闪存工具,用于将操作系统镜像写入SD卡或USB驱动器。
- 2. 在Windows、Linux和MacOS上使用Balena Cli安装镜像。
- Balena CLI 是用于balenaCloud或openBalena的命令行界面。 您可以从balena-io 下载安装程序或独立包,然后正确安装到您的PC上,然后您可以使用balena的"local flash"令选项将Linux镜像写入SD卡或USB驱动器。
$ sudo balena local flash path/to/xxx-bpi-m4-berry-xxx.img.zip
$ sudo balena local flash path/to/xxx-bpi-m4-berry-xxx.img.zip --drive /dev/disk2
$ sudo balena local flash path/to/xxx-bpi-m4-berry-xxx.img.zip --drive /dev/disk2 --yes
- 3. 在Linux上使用dd命令安装镜像,如果SD卡自动挂载,请取消挂载SD卡设备/dev/sdX分区。实际上,bpi-copy与此dd命令相同。
$ sudo apt-get install pv unzip
$ sudo unzip -p xxx-bpi-m4-berry-xxx.img.zip | pv | dd of=/dev/sdX bs=10M status=noxfer
- 4. 使用bpi-tools在Linux上安装镜像,将SD卡插入Linux PC并运行以下命令:
$ sudo apt-get install pv unzip
$ sudo bpi-copy xxx-bpi-m4-berry-xxx.img.zip /dev/sdX
DTB overlay
- 1. DTB overlay 用于40引脚GPIO的多功能配置,并安装在vfat引导分区中,您可以使用mount命令检查挂载点。
root@bananapi:~# ls /boot/overlays/
custom_ir.dtbo pwm_b-backlight.dtbo spi0.dtbo
ds3231.dtbo pwm_c-beeper.dtbo uart1_cts_rts.dtbo
hifi_pcm5102a.dtbo pwm_cd-c.dtbo uart1.dtbo
hifi_pcm5122.dtbo pwm_cd.dtbo uart2.dtbo
i2c0.dtbo pwm_ef.dtbo waveshare_tft24_lcd.dtbo
i2c1.dtbo pwm_ef-f.dtbo waveshare_tft35c_lcd.dtbo
pwm_ab.dtbo sdio.dtbo waveshare_tft35c_rtp.dtbo
- 2. 更新vfat /boot/boot.ini中的overlay设置以启用所需的overlay。默认启用i2c0、spi0和uart1。
# 要加载的overlay
# 示例组合:
# spi0 i2c0 i2c1 uart0
# hktft32
# hktft35
setenv overlays "i2c0 spi0 uart1"
- 3. 必须重新启动板以加载DTB overlay。
WiringPi
- 注意:此WiringPi仅支持将40引脚GPIO设置为输出、输入或软件PWM,对于io功能如i2c、spi、pwm等,您必须在boot.ini中启用DTB overlay。
- 1. 构建并安装WiringPi,对于Debian系统,您必须在构建之前启用 sudo 。
$ sudo apt-get update
$ sudo apt-get install build-essential git
$ git clone https://github.com/BPI-SINOVOIP/amlogic-wiringPi
$ cd amlogic-wiringPi
$ chmod a+x build
$ sudo ./build
- 2. Run gpio readall to show all 40pins status.
- 3. BPI GPIO Extend board and examples in amlogic-wiringPi/examples
- blinkall, blink all pin header gpios, no extend board.
- lcd-bpi, BPI LCD 1602 display module example.
- 52pi-bpi, BPI OLED Display Module example.
- matrixled-bpi, BPI RGB LED Matrix Expansion Module example.
- berryclip-bpi, BPI BerryClip Module
RPi.GPIO
- Build and install, 对于Debian系统,您必须在构建之前启用 sudo 。
$ sudo apt-get update
$ sudo apt-get install build-essential python3 python3-pip python3-dev python3-setuptools git
$ git clone https://github.com/Dangku/RPi.GPIO-Amlogic.git
$ cd RPi.GPIO-Amlogic
$ sudo python3 setup.py clean --all
$ sudo python3 setup.py install
- Create and install wheel package
$ sudo python3 setup.py bdist_wheel
$ sudo pip3 install dist/RPi.GPIO-XXX.whl
- Install from git source directly without development
$ sudo pip3 install git+https://github.com/Dangku/RPi.GPIO-Amlogic.git
- If the package is already installed, it should be uninstalled before installing the new one, or installing the new one with --force-reinstall option.
WiringPi2-Python
- Build and install, 对于Debian系统,您必须在构建之前启用 sudo 。
$ sudo apt-get update
$ sudo apt-get install build-essential python3 python3-dev python3-setuptools swig git
$ git clone --recursive https://github.com/Dangku/WiringPi2-Python-Amlogic.git
$ cd WiringPi2-Python-Amlogic
$ sudo python3 setup.py install
Luma.Examples
- luma.examples use GPIO.BCM gpio mode default, so you should map 40pin header pins to bcm gpio number and connect the hardware correctly.
- 1. build and install RPi.GPIO
$ sudo apt-get update
$ sudo apt-get install build-essential python3 python3-dev python3-setuptools git
$ git clone https://github.com/Dangku/RPi.GPIO-Amlogic.git
$ cd RPi.GPIO-Amlogic
$ sudo python3 setup.py clean --all
$ sudo python3 setup.py install
- you can change the bcmledpin variable in test/led.py to your hardware backlight gpio and run it to check RPi.GPIO works well.
$ sudo python3 test/led.py
- hardware backlight will repeat on and off
- 2. luma.examples libs install
$ sudo usermod -a -G i2c,spi,gpio pi
- if group does not exist, the following command will create it:
$ sudo groupadd --system xxx
$ sudo apt-get install python3-dev python3-pip libfreetype6-dev libjpeg-dev build-essential
$ sudo apt-get install libsdl-dev libportmidi-dev libsdl-ttf2.0-dev libsdl-mixer1.2-dev libsdl-image1.2-dev
$ git clone https://github.com/rm-hull/luma.examples.git
$ cd luma.examples
- install luma.core, luma.emulator, luma.lcd, luma.le-matrix, luma.oled pip libs, make sure this step without error or downloading interrupted, try again if get errors
$ sudo -H pip install -e .
- or
$ sudo -H pip3 install -e .
- for debian buster(python 3.7) which does not include /usr/bin/pip in package python3-pip, and will get the following errors when install luma packages with pip3
...
WARNING, No "Setup" File Exists, Running "buildconfig/config.py"
Using UNIX configuration...
/bin/sh: 1: sdl2-config: not found
/bin/sh: 1: sdl2-config: not found
/bin/sh: 1: sdl2-config: not found
...
- install sdl2 related packages to fix this issue, then install luma libs again with pip3
$ sudo apt-get install libsdl2-dev libsdl2-ttf-dev libsdl2-mixer-dev libsdl2-image-dev
$ sudo -H pip3 install -e .
- check installed luma pip libs
$ pip3 list | grep luma
luma.core 2.4.0
luma.emulator 1.4.0
luma.lcd 2.10.0
luma.led-matrix 1.7.0
luma.oled 3.11.0
- 3. examples test
- Enable i2c or spi overlays before running test examples
$ cd examples
$ sudo python3 bounce.py --config ../conf/ili9341.conf
其他
为Debian启用sudo
- 默认情况下,Debian镜像不安装sudo,用户可以使用"su -"命令切换到root用户。如果您喜欢sudo,您可以安装它。
$ su root
Password:(enter bananapi)
# apt-get update
# apt-get install sudo
# adduser pi sudo
- 然后,请注销并重新登录。
