Learn How to Setup Dietpi for the Raspberry Pi?

Overview of Dietpi

Dietpi is a lightweight, optimized operating system based on Debian Linux and made specifically for single-board computers like the Raspberry Pi. Some key advantages of Dietpi include:

  • Optimized performance: Dietpi only includes software and processes essential for functionality, freeing up system resources for your tasks and projects. This optimization boosts speeds across the entire device.
  • Low memory usage: With a focus on minimizing bloatware and unnecessary processes in the background, Dietpi uses significantly less memory than standard Raspberry Pi OS distributions.
  • Support for Raspberry Pi SBCs: Dietpi is designed specifically with Raspberry Pi and other single-board ARM devices in mind, ensuring excellent compatibility.
  • Streamlined software installation: Dietpi features its own software catalog system called dietpi-software which greatly simplifies installing over 400 popular Linux programs with just a single terminal command.

Why Choose Dietpi Over Standard Pi OS?

While Raspberry Pi OS (previously called Raspbian) works well, it still includes some bloat from its Debian base. Dietpi streamlines the entire OS further.

Some specific advantages of Dietpi:

  • Uses only 200 MB storage for OS files instead of 1 GB+ for Pi OS
  • Reduced memory usage so more RAM available for programs
  • Special dietpi-software catalog with tons of apps optimized for ARM
  • Additional performance tweaks for benchmark boosts
  • Extra settings to easily enable security features like the firewall
  • Lower CPU load averages and temperature due to utilizing less resources
  • Native support for OLED displays, custom RPi HATs, and specialized Pi hardware

Overall, Dietpi brings extra speed, stability, and convenience without losing compatibility – perfect for Pi projects with heavy workloads.

Installing Dietpi on Raspberry Pi

With Dietpi offering such great benefits, installing Dietpi is straightforward process. Here’s how:

What You’ll Need

  • Raspberry Pi 2/3/4 (DietPi Core also supports Pi Zero and 1)
  • 8 GB+ MicroSD Card (Class 10 recommended)
  • Micro USB power supply
  • Keyboard and mouse
  • Monitor/TV with HDMI input
  • Ethernet cable or WiFi dongle/adapter (for internet connectivity)

Downloading the Dietpi Image

  1. Visit DietPi’s website and download DietPi for Raspberry Pi to your desktop
  2. Extract the .7z compressed file once finished. This contains the installer image file.

Using Etcher to Flash Dietpi

Etcher provides an easy way to write OS images onto SD cards and handles compression/extraction automatically.

  1. Insert your SD card into the computer or a connected USB card reader.
  2. Open Etcher Landing page and click Download to get latest version for your OS.
  3. Once installed, open Etcher and select the DietPi .img file you extracted earlier.
  4. Choose your connected SD card and click Flash. This writes Dietpi to the SD card ready for first boot on a Pi.

That covers installation. Remove the SD card from your computer and insert it into the Raspberry Pi when ready to complete Dietpi setup.

Initial Setup and Configuration

With Dietpi flashed to the SD card, plug it into your Raspberry Pi board, connect the power supply, display, keyboard/mouse and boot it up to walk through configurations required before use.

Connecting and Running Through Options

Here is a quick overview of choices and changes to make on first booting Dietpi:

  • Select language and localization options
  • Configure your internet connection:Ethernet or WiFi details
  • Change default password from dietpi
  • Update DietPi and installed software: dietpi-update
  • Reboot once to complete update installation
  • Configure software options and performance settings

We’ll go through internet connectivity, the dietpi-software tool for managing apps, overclocking performance tweaks and other options in the following sections.

Getting DietPi Online for Software Installs

An internet connection unlocks installing any software package directly on your device.

For Ethernet Cable Networks

Plug your Raspberry Pi directly into a router or wall port on your wired home/office network using an Ethernet cable.

DietPi automatically configures network connection details over a cable connection without any changes needed. Run dietpi-config and under Network Options, select Ethernet connection to check it’s activated correctly with an IP Address.

For Wireless WiFi Networks

To connect Dietpi to wireless networks, you need to setup WiFi details:

  1. Plug a compatible WiFi dongle/adapter into USB port if Pi model doesn’t have inbuilt WiFi like Raspberry Pi 3 or 4.
  2. Run DietPi Config Tool:
  3. sudo dietpi-config
  4. Choose WiFi Networking Options, Input your SSID (wireless name), select security type, enter password to connect.
  5. Finish by selecting option for automatic WiFi connection on boot to store details.

Once connected to WiFi or ethernet, run software update commands next.

DietPi Software Management With dietpi-software

One particularly helpful tool included in DietPi is dietpi-software. This custom tool handles finding, installing, updating and removing software specifically optimized for your Raspberry Pi device.

It downloads precompiled software from DietPi’s servers where available, avoiding long compile times with complex source code. For unsupported packages it utilizes Debian’s standard APT repositories transparently in the background instead.

Here are key commands to use dietpi-software for quick software installs:

  • dietpi-software – Runs management tool, browse and install software selections
  • dietpi-software reinstall [id] – Fresh reinstall of existing app using id number
  • dietpi-update – Updates all DietPi components
  • dietpi-software list – Lists all software with categories and id

Hundreds of Linux apps are available including servers, monitoring tools, VPNs, editors, programming languages, media software and libraries suited to the PI.

Browsing categories displays descriptions and optimization status. Notable favorites like RetroPie emulators, Home Assistant, WireGuard and many others can be installed in minutes with a few terminal commands.

Optimizing DietPi Performance

DietPi automatically applies certain optimizations for great performance on all Pi models. Additional options you can toggle specifically:

Overclocking for Raspberry Pi 2/3/4

Overclocking pushes hardware past stock speeds. DietPi uses performance testing results tailored to each model selecting maximum stable values.

Overclock presets bring noticeable speed boosts without affecting system stability. It’s recommended for heavier workloads.

In dietpi-config, navigate to:

  • Performance Options > Overclocking:
    • Review details and select your level up to Turbo.
    • Run benchmark to confirm improved performance.

Higher overclock Presets require adequate power supply and cooling. A heatsink helps regulate temperatures on extended loads.

Adjust GPU Memory Split

DietPi splits RAM intelligently between GPU and ARM CPU according to model. The fraction can be customized depending on how graphics or CPU intensive your projects are. Options:

  • More GPU Memory – Needed for 3D graphics work, vision processing
  • Balanced Split – Typical usage for web, coding etc
  • More RAM for CPU – RAM heavy apps like databases or web servers

Adjust GPU Memory percentages + reboots in DietPi Config Tool under Performance Options as necessary.

Thread Scheduling Priorities

For multithreaded apps particularly big node servers, databases and media encoding pipelines, DietPi has Thread Scheduling Priorities options.

Global modes that optimize thread scheduling across DietPi:

  • Performance mode
  • Normal mode
  • Eco mode

Set mode based on your workflow needs and CPU requirements via DietPi Config Tool.

governor Settings / CPU Scaling

CPU governors handle dynamic frequency scaling that adjusts Pi processor speeds based on current workload.

DietPi’s tuned defaults work great but can toggle options like:

  • Performance – Always run CPU cores at max speed
  • On-Demand – Scale CPU speeds up/down as needed. Default.
  • Conservative – More gradual stepping of MHz based on load
  • Power Save – Low speeds favoring efficiency over performance

Adjust Scaling Governor via DietPi Config Tool as necessary for your projects.
