Porting Linux to the M32R Processor

Overview This paper has ported a Linux system to the Renesas M32R processor, which is a 32-bit RISC microprocessor designed for embedded systems, and with an on-chip-multiprocessor feature. So far, both of UP (Uni-Processor) and SMP (Sym-metrical Multi-Processor) kernels (based on 2.4.19) have been ported and they are operating on the M32R processor. A Debian GNU/Linux based system has been also developed on a diskless NFS-root environment, and more than 300 unofficial .deb packages have already been prepared for the M32R target. This paper describes this new architecture port in detail and explains the current status of the Linux/M32R project.
