Is the update process for your embedded Linux devices cumbersome, error-prone, and lacking in security? SWUpdate will completely transform the way you update your firmware! It is a powerful Linux update agent designed to provide an efficient and secure method for updating embedded Linux systems in the field. Whether for local updates or OTA updates, SWUpdate can handle it with ease.
What is SWUpdate?
SWUpdate is a flexible and secure update framework for embedded Linux systems. It supports both local and OTA (Over-the-Air) updates, offering various update strategies while prioritizing security from the very beginning. It can update various components of the device, including rootfs, kernel, bootloader, and microcontroller firmware, and supports multiple embedded storage media such as eMMC, SD cards, Raw NAND, UBIFS, NOR, and SPI-NOR flash.
Main Features of SWUpdate:
- • Comprehensive Component Updates: Supports updating all components of the device, including rootfs, kernel, bootloader, and microcontroller firmware, ensuring a complete system update.
- • Wide Storage Media Support: Compatible with various embedded storage media, from common eMMC and SD cards to various flash types, adapting to different hardware platforms.
- • Flexible Update Strategies: Supports multiple update strategies to meet the needs of different application scenarios.
- • Efficient Update Mechanism: Utilizes a streaming mode, eliminating the need for temporary copies of update files, saving storage space and time.
- • Multi-Interface Support: Supports both local and OTA update methods, providing convenient and flexible updating.
- • Robust Security Mechanisms: Supports encryption, signing, and verification of update files to prevent malicious attacks. Compatible with various encryption libraries such as OpenSSL, mbedTLS, and WolfSSL.
- • Atomic Updates: Employs an atomic update mechanism to ensure the safety and reliability of the update process, allowing rollback to previous versions even if the update fails.
- • Extensibility: Built-in Lua interpreter allows users to customize update rules to meet personalized needs.
- • User-Friendly Interface: Integrated web server for easy monitoring and management of the update process. Integrated REST client connects to hawkBit for convenient cluster updates.
- • Custom Extensions: Supports custom handlers for installing FPGA firmware, microcontroller firmware, etc.
- • Incremental Updates: Implements incremental updates based on librsync, reducing network traffic and update time.
- • Compact Design: Minimal resource usage, suitable for generating recovery systems.
- • Programmability: Can be controlled via libraries and provides progress interfaces to report update status to applications/HMI.
