What is Linux/M32R?

Linux/M32R is a Linux distribution for M32R, which is a 32-bit RISC microprocessor of Renesas Technology.

The Linux/M32R supports both 2.4 and 2.6 kernels; 2.4.31 and 2.6.14 kernels are now available.
Several device drivers (LAN, CF, USB, MTD, etc.) have already ported.

These kernels also support SMP features for a multiprocessing environment on an M32R multiprocessor system on FPGAs and/or an M32R single-chip multiprocessor.

The Linux/M32R is based on the Debian GNU/Linux distribution. More than 300 unofficial .deb packages are available.
