Seeed Studio reTerminal

Current Status

Supported	SDK	Provisioning
🟢 Target actively maintained	🟢 x86-64 and aarch64 container images	🟡 eMMC storage

Seeed Studio's reTerminal is an industrial HMI with the same Raspberry Pi 4 compute module at its heart, but wrapped in a touchscreen interface, expanded I/O, and a form factor designed for real-world deployment.

Since the reTerminal is just a Raspberry Pi 4 with extra peripherals, you can use Avocado OS to develop your application on a Raspberry Pi 4, then quickly retarget your finished Linux image for production hardware.

🚀 Getting Started

Get up and running with the Avocado Linux SDK in minutes.

Prerequisites

• A Mac (macOS 10.12+) or Linux (Ubuntu 22.04+, Fedora 39+) development machine
• Docker installed
• 3GB+ available disk space

Installing and running the SDK

1. Install the Avocado CLI and append the location of the avocado executable to your PATH environmant variable.

2. Create your project workspace:

mkdir avocado-reterminal

3. Initialize a new project:

cd avocado-reterminal
avocado init

4. Replace qemux86-64 with reterminal as target in avocado.toml:

[runtime.dev]
target = "reterminal"

5. Install all components (SDK, extensions, and runtime dependencies):

avocado install -f

⚙️ Provisioning

We are actively working on a provisioning guide for the reTerminal.

🧰 Hardware-in-the-Loop (HIL)

We are actively working on Hardware-in-the-Loop (HIL) development for the reTerminal.

🤖 Zero-Friction Hardware Retargeting: Raspberry Pi 4 → reTerminal

We take a computer vision application running on a Raspberry Pi 4 and move it to the Seeed Studio reTerminal in under 10 minutes—with no code changes and no rebuilds.

Why it matters

Hardware changes are one of the most common sources of delays in embedded projects. Avocado OS makes hardware choice a late-stage decision—not a risky one—by keeping your build environment consistent across devices.

This walkthrough covers:

• End-to-end retargeting from Raspberry Pi 4 to reTerminal
• How Avocado OS removes BSP complexity
• The exact steps for going from dev board to production-ready hardware
