System transplanting method based on RISC-V processor and related component

Abstract

The invention discloses a system transplanting method based on a RISC-V processor. The system transplanting method comprises the following steps: calling an RISC-V processor; the V processor buildinga cross compiling environment corresponding to the tool chain; calling a matching kernel in a cross compiling environment to compile the kernel by using a RISC-V system architecture, and generating akernel mirror image file without a root file system; calling a linux command and a tool to generate an executable program; adding a system preset necessary directory to generate a mirror image file; reconfiguring and compiling a linux kernel according to the mirror image file; the method comprises the steps of generating a new kernel mirror image file, embedding the generated new kernel mirror image file into a bootstrap program, and loading the bootstrap program obtained after embedding into a memory of a RISC-V processor, so that a linux operating system capable of running in the RISC-V processor can be generated, and system transplantation based on the RISC-V processor is realized. The invention also discloses a system transplanting device and equipment based on the RISC-V processor, and a readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of processors, in particular to a system transplantation method, device, equipment and readable storage medium based on RISC-V processors. Background technique [0002] In order to enable the operating system to run on a certain microprocessor or microcontroller, it is necessary to transplant the embedded operating system. Among many embedded operating systems, Linux is currently the fastest growing and most widely used. Linux with excellent performance and open source code has many advantages such as small size, scalable kernel, perfect network function, and strong portability, and is widely used as an embedded operating system. [0003] RISC-V (Reduced Instruction Set Computer–FIVE) processor is an emerging processor, which is an open instruction set architecture (ISA) based on the principle of reduced instruction set computing (RISC). It is based on the continuous development and maturity of the i...

Problems solved by technology

[0004] Currently there are some linux system transplantation technologies, but most of them are for ARM, X86 and other processors, and there is no system transplantation method for emerging RISC-V processors; Due to the huge difference, it is impossible to call the system migration process of traditional processors to perform system migration based on RISC-V processors
