LinuxSH Wiki

This is the LinuxSH wiki. LinuxSH is a port of the Linux kernel to the SuperH and SH-Mobile family of processors from Renesas Technology, STMicroelectronics, the former SuperH, Inc., and legacy parts from Hitachi.

Starting Points and Links

Getting Started

• LinuxSH Support

  • Processors

  • Systems

• Kernel

  • Browse kernel source with ViewCVS.

  • Getting source

  • Using the drop-in tree

  • Debugging

  • Using Early User Space

  • Kernel Status Matrix

• Toolchains

  • There are many different options for toolchains, sticking with the pre-built binary toolchains is the quickest way to get started, but anyone interested in development is encouraged to build from source. In general, pre-3.x versions of GCC should be avoided completely, as these are completely unsupported, and have their fair share of problems. When using a vendor toolchain, contact the vendor for support first before posting about it to any of the community support forums.

  • Binary:

    • http://www.sh-linux.org RPM repository maintained by Sugioka Toshinobu.

      • pre-built glibc-based toolchains, as well as many pre-built RPMs for sh.

    • http://ftp.snapgear.org/pub/snapgear/tools/sh-linux/ Old pre-built toolchains and source from snapgear.

  • Source:

    • Crosstool028rc37: How to use crosstool to build an SH toolchain (OLD VERSION)

    • Crosstool038: Building a toolchain with newer components (NEW)

    • uClibc -- Building uClibc-based toolchains (needed for nommu).

    • Gentoo Crossdev: How to use crossdev on Gentoo

• Todo list of kernel stuff that needs to get done.

• Working with the Wiki

  • HelpForBeginners: to get you going

  • FindPage: search or browse the database in various ways
