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 scheduling
  • Memory management
  • File system management
  • Device driver management
  • Network protocol stack

Supported versions:

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).

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.

Supported Devices​
