Introduction

This page describes the feature of patches for TX49xx boards on CE Linx. TX49xx is mips architecture MPU from TOSHIBA.

Boards

We checked the patch on the following boards

  • TOSHIBA RBHMA4200 (RBTX4927)
  • TOSHIBA RBHMA4400 (RBTX4937)
  • TOSHIBA RBHMA4500 (RBTX4938)

Build Environment

We checked with the toolchain below

  • 2.6.8.1
    • gcc-3.3.2 / glibc-2.5.2 / binutils-1.15
    • gcc-3.4.2 / glibc-2.3.2 / binutils-1.15
    • MIPS toolchains from Sony (ToolChains)
  • 2.6.9
    • gcc-3.3.2 / glibc-2.5.2 / binutils-1.15
    • gcc-3.4.2 / glibc-2.3.2 / binutils-1.15
    • MIPS toolchains from Sony (ToolChains)
  • 2.6.10
    • gcc-3.4.2 / glibc-2.3.2 / binutils-1.15
    • MIPS toolchains from Sony (ToolChains)

Available Devices

  • Ether

How To Build

  • 2.6.8.1
$ tar jxf linux-2.6.8.1.tar.bz2
$ cd linux-2.6.8.1
$ patch -p1 < rbtx49.linux-2.6.8.1-2.patch

big endian
$ mkdir ../build_be
$ make SUBARCH=mips O=../build_be tx-r4k-be_defconfig
$ make SUBARCH=mips O=../build_be

little endian
$ mkdir ../build_le
$ make SUBARCH=mips O=../build_le tx-r4k_defconfig
$ make SUBARCH=mips O=../build_le
  • 2.6.9

We needed the patch for Makefile to build.

$ tar jxf linux-2.6.9.tar.bz2
$ cd linux-2.6.9
$ patch -p1 < rbtx49.linux-2.6.9-2.patch
$ patch -p1 < Makefile-mips.linux-2.6.9-1.patch

big endian
$ mkdir ../build_be
$ make SUBARCH=mips O=../build_be tx-r4k-be_defconfig
$ make SUBARCH=mips O=../build_be

little endian
$ mkdir ../build_le
$ make SUBARCH=mips O=../build_le tx-r4k_defconfig
$ make SUBARCH=mips O=../build_le
  • 2.6.10
$ tar jxf linux-2.6.10.tar.bz2
$ cd linux-2.6.10
$ patch -p1 < rbtx49.linux-2.6.10-2.patch

big endian
$ mkdir ../build_be
$ make SUBARCH=mips O=../build_be tx-r4k-be_defconfig
$ make SUBARCH=mips O=../build_be

little endian
$ mkdir ../build_le
$ make SUBARCH=mips O=../build_le tx-r4k_defconfig
$ make SUBARCH=mips O=../build_le
  • LTT on 2.6.10
  Kernel:
    # tar jxf linux-2.6.10.tar.bz2
    # cd linux-2.6.10
    # patch -p1 < rbtx49.linux-2.6.10-2.patch
    # patch -p1 < ltt-2.6.10-tb5-mips.patch
    edit .config to enable CONFIG_RELAYFS_FS and CONFIG_LTT.
    # make SUBARCH=mips rbtx49_defconfig
    # make

  LTT:
    # tar zxf TraceToolkit-0.9.6-tb.tar.gz
    # cd TraceToolkit-0.9.6
    # patch -p1 < TraceToolkit-0.9.6-tb-mips.daemon.patch
   - tracedaemon
      # ./configure --prefix=xx --target=mipsel-linux --host=mipsel-linux --build=`./config.guess` --without-glib --without-gtk
      # make -C LibUserTrace UserTrace.o
      # make -C LibUserTrace LDFLAGS="-static"
      # make -C Daemon LDFLAGS="-static"
   - tracevisualizer
      # ./configure --prefix=xx
      # make -C LibLTT LDFLAGS="-static"
      # make -C Visualizer LDFLAGS="-static"

Future Work

Here is a list of things that could be worked on for this feature:
