Cross Toolchain

4

The next step in building a Linux system for running on Intel XScale

®

microarchitecture is to

generate a cross-toolchain for building the kernel and applications from the IA Linux host.
Currently, we use a toolchain built using the crosstool build scripts (

http://kegel.com/crosstool

).

We currently build for the armv5l-linux target.

After the latest version of the script is downloaded a couple changes need to be made:

1. Edit the arm-xscale.dat file to change the following line:

TARGET=arm-xscale-linux-gnu

To

TARGET=armv5l-linux

2. Edit the demo-arm-xscale.sh to select which versions of gcc and glibc are to be used.

Comment out or remove all of the statements starting with "eval `cat" and replace them with
the following statement:

eval `cat arm-xscale.dat gcc-3.4.3-glibc-2.3.5.dat` sh all.sh --notest

Change the RESULTS_TOP variable to the directory where the tools are to be installed (the default
is "/opt/crosstool")

After the changes are made the demo-arm-xscale.sh script needs to be run. Next, add the /opt/
crosstool/bin (or the path where the tools were built) to your PATH variable.
