Husarion OS Flasher Image (HOFI)
What is HOFI?
The Husarion OS Flasher Image (HOFI) is a unified tool designed to simplify the operating system installation process across different Single Board Computers (SBCs) used in Husarion robots.
Whether your robot runs on a Raspberry Pi (SD card) or an x64 SBC with an eMMC or SSD, HOFI provides a standardized, error-free, and user-friendly way to flash OS images.
Why HOFI?
Problems Without HOFI
Without HOFI, flashing OS images across different SBCs is inconsistent, error-prone, and requires manual work. Expand the section below to see the key challenges:
🚨 Common Issues Without HOFI
| 🚨 Problem | 😖 Impact |
|---|---|
| 🔀 Different flashing methods for different SBCs | Users must manually switch between SD card flashing (for Raspberry Pi) and dd-based flashing (for x64 devices with eMMC/SSD), leading to confusion and extra effort. |
| 🔧 No built-in flashing system for eMMC/SSD devices | SBCs with non-removable storage (like Intel NUC, UP Board) require a separate Linux environment just to run dd. |
⚠️ Error-prone manual dd flashing | dd commands are easy to misconfigure, and can accidentally wipe the wrong drive. |
| 📦 No standard storage for OS images | Users must manually track and re-download OS images each time, with no dedicated partition for keeping them. |
| 🐢 Unoptimized minimal OS solutions | Existing lightweight Linux distros for flashing are often bloated or lack automation, requiring extra setup. |
| 🌐 No built-in networking for easy access | Users must manually configure networking, IP addresses, and SSH access to reach the flashing environment. |
How Does HOFI Solve This?
HOFI provides a standardized, easy, and error-free way to flash OS images on any Husarion-supported SBC. Expand the section below to see how HOFI solves each problem:
