Abstract
This paper describes the design and implementation of executing ELF files for ARM-based multi-process micro-kernel embedded operating system, including overview of ELF files, key techniques of executing ELF files, such as installing command-line parameters and environment variables, loading ELF file, setting related registers and PCB fields, and starting the executable ELF file, etc. Based on the functionality of executing ELF files described in this paper, the corresponding shell interpreter and shell commands can be designed and executed. At the final, the paper provides some demo examples of shell commands to show the effect.
