#### Linux Kernel

The Linux kernel is responsible for managing the processor and other hardware resources, providing an interface between users and applications and the hardware. Its main functions include interrupt and clock management, process management, memory management, file system management, device driver management, and network protocol stack.

Version: 6.1 and 6.6。

- [https://gitee.com/bianbu-linux/linux-6.6](https://gitee.com/bianbu-linux/linux-6.6) (LTS)

#### 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 media (such as SD card, eMMC, SPI Flash, SSD, network).

Version: u-boot-2022.10。

Source code: [https://gitee.com/bianbu-linux/uboot-2022.10](https://gitee.com/bianbu-linux/uboot-2022.10)

#### OpenSBI

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

Version: 1.3。
