Bassano del Grappa, Italy -  14 April 2025

ACube Systems is pleased to announce a new release of the U-Boot firmware for its Sam440 line of motherboards.

Following the recent update for the Sam460, the Sam440 now also benefits from enhanced support, including compatibility with NVMe SSDs. Additionally, this update introduces support for Radeon RX and Radeon HD graphics cards.

This release represents a significant investment of time and resources. Nevertheless, we have chosen to offer it at the symbolic price of €3.99.

Highlights of this release include:

• Support for Radeon RX graphics cards (*)
• Improved support for Radeon HD graphics cards (*)
• NVMe SSD driver: boot directly from NVMe devices using a PCIe adapter (*)
• Driver for the PCIe SATA2 Silicon Image 3132 controller, with support for booting from SSDs and DVDs (*)
• Enhanced RAM access speed on Sam440ep-flex boards
• New graphical interface style
• Revised ‘sata’ command, now displaying more detailed information about drivers and connected devices
• Serial console improvements: menu navigation via the W (up) and S (down) keys
• General bug fixes and overall improvements
• Unified source code for the 460ex and 440ep platforms

Note:

Features marked with an asterisk (*) require a PCI-to-PCIe bridge.
Radeon RX and Radeon HD graphics cards also require a specific driver (to be sold separately by A-EON Technology once available) for use with AmigaOS 4.

Purchase the update:

The update is available through our online store.
For those not comfortable performing the update themselves, we also offer pre-programmed, fully updated U-Boot chips.

Additional Information:

UBoot makes use of GPL-licensed code and is therefore released under the terms of the GPL.
