Toolchain
Interested in building a toolchain for the MSP's ARM XScale processor? Here's how I made it work...
You need to download Crosstool, a set for script and patches for building crosscompile toolchains.
We'll be specifically targeting the following package profile:
gcc-3.4.3 glibc-2.3.2
Since we're targeting the XScale processor, we need to apply a few patches for the ARM architecture with VFP floating point support, as made available here.
Specifically, you need the following patches:
patches/gcc-3.4.3/gcc-3.4.3-arm-softvfp.patch patches/glibc-2.3.2/glibc-2.3.2-initfini.patch patches/glibc-2.3.2/glibc-2.3.2-output_format.patch patches/glibc-2.3.2/glibc-2.3.2-sysctl.patch patches/glibc-linuxthreads-2.3.2/glibc-linuxthreads-2.3.2-initfini.patch
Once you've downloaded, unpacked, and copied the patches into their appropriate locations in the crosstool tree, you're read to start building. My build script looked like the following:
#!/bin/sh set -ex export TARBALLS_DIR=`pwd`/downloads export RESULT_TOP=/usr/local/arm-linux export GCC_LANGUAGES="c,c++" export KERNELCONFIG=`pwd`/arm.config export TARGET=arm-linux export TARGET_CFLAGS="-O" export GCC_EXTRA_CONFIG="--with-cpu=iwmmxt --enable-cxx-flags=-mcpu=iwmmxt --with-fpu=vfp" export GLIBC_EXTRA_CONFIG="--without-fp" export BINUTILS_DIR=binutils-2.15 export GCC_DIR=gcc-3.4.3 export GLIBC_DIR=glibc-2.3.2 export LINUX_DIR=linux-2.6.14 export LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0 export GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.2 sh all.sh --notest echo Done.
Let 'em rip.
