Introduction

Bianbu NAS (Network Attached Storage) is a system derived from the Bianbu operating system, specifically tailored for NAS products. It includes applications (openmediavault, Docker, and other common softwares), frameworks, libraries, runtime environments, the Linux kernel, bootloader (U-Boot), and supervisor binary interface (OpenSBI). Our goal is to provide a reference design for NAS software, enabling the development of drivers and applications.

Linux Kernel​

The Linux kernel manages the processor and hardware resources, serving as an interface between users, applications, and hardware. Its core functions encompass interrupt handling, clock management, process scheduling, memory management, file system management, device driver management, and the implementation of the network protocol stack.

Version: 6.1.

U-Boot​

U-Boot is a bootloader responsible for initializing specific hardware and loading the Linux kernel image, device tree, and initial RAM filesystem from various media such as SD cards, eMMC, SPI Flash, SSDs, and networks.

Version：u-boot-2022.10。

Source Code：https://gitee.com/bianbu-linux/uboot-2022.10

OpenSBI​

OpenSBI is an implementation of the Supervisor Binary Interface for RISC-V architecture processors. It runs as firmware in M-mode, providing an interface for bootloaders, hypervisors, and operating systems to access hardware.

Version：1.3。

Supported Devices​

Bianbu NAS currently supports the following hardware devices:

Firmware​

Bianbu NAS firmware is available in two versions, based on Bianbu OS 23.10 and Bianbu OS 24.04, referred to as Bianbu NAS 23.10 and Bianbu NAS 24.04, respectively. The former has undergone several iterations and is more stable; it is recommended for download. However, if you require the latest OS and SDK, you may opt for the latter, though it is still under development and may have stability risks.

  • Bianbu NAS 23.10 (Latest version: v1.0.14)
  • Bianbu NAS 24.04 (Latest version: v2.0beta2)
