注意：如果你使用的是带HDMI的桌面版，一定要选择一个电流足够的适配器，否则会导致异常重启。

设置 root 密码

sudo passwd root

屏幕翻转

  • 带ui的新系统
    如果你的屏幕是180度倒置的，需要设置下屏幕：

    1. preferences->screen configuration
    2. 选择HDMI屏幕，右键->Orientation->inverted
  • 命令行的老系统
    1. sudo nano /boot/config.txt
    2. display_hdmi_rotate=2

开启sshd

  • 方法1：通过界面UI
    如果烧录是没有配置sshd，我们可以在进入系统以后启动：

    sudo systemctl enable ssh
sudo systemctl start ssh
  • 方法2：通过SD
    当没有屏幕时，我们可以通过在sd boot盘的跟目录下创建SSH空文件，来启用默认的sshd配置。用户名pi，密码respberry

安装pyenv

系统默认python3，有时候你需要运行的项目是python2的，我们需要pyenv

git clone https://github.com/pyenv/pyenv.git ~/.pyenv

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.profile
echo 'export PATH="$PYENV_ROOT/libexec:$PATH"' >> ~/.profile
echo 'eval "$(pyenv init --path)"' >> ~/.profile
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
exec $SHELL -l

Raspberry Pi 1 Model B+

On the other hand, the BCM2835 uses a single core and thread 32-bit microprocessor. Once again, it features a clock speed of 700 Mhz. However, it has a turbo capability to boost clock frequencies up to 1 GHz. Unfortunately, this feature is absent from the BCM2711.
The BCM2835 is an SoC that Broadcom Semiconductors developed.  As we have briefly mentioned in the introduction, SoC packages such as the BCM2835 make devices such as the Raspberry Pi Zero possible. Additionally, The Raspberry Pi Foundation features the BCM2835 in the Raspberry Pi A, A+, B, B+, and the Raspberry Pi Zero W. Moreover, you can find it in rare models such as the Raspberry Pi Compute Module 1.

Since it’s an older chip package, you’re unlikely to find it in newer microcontrollers or single-board computers. However, its capabilities and peripherals are still worth exploring.
  • Core Processor Architecture: ARM
  • Processor Speed: 700 MHz
  • Core Processor Sub-Architecture: ARM1176JZF-S processor
  • RAM: 512MB
  • SODIMM Board Size: 6.5x3.0 cm
  • Edge Connector Pins: 200
  • On-Board Flash Memory: 4GB eMMC
  • GPU: VideoCore IV GPU running at 250MHz

安装系统

准备大于8G的SD

Raspberry Pi Imager

根据前面的介绍，我们知道我们的板子是32架构，所以我们要选择32bit的系统：

说明：

  • 一定要选好的sd卡和读卡器，否则可能浪费很多时间。
  • 右下角的设置是可以预设一些参数的，对于无屏场景，很有用

经过耐心的等待，就会提示校验成功，可以拿下sd插入设备了。
