5 Installing the Software
The following section describes how to install and configure the Codewarrior Integrated
Development Envionment (IDE) software required to run the demonstration examples
and to exercise the RD9Z1-638BJBEVM in an evaluation environment.
5.1 Installing CodeWarrior
NXP's CodeWarrior provides an integrated environment that brings together all of the
software resources and capabilites requried to use the RD9Z1-638BJBEVM reference
design kit. If a previous version of CodeWarrior exists on the PC attached to the
RD9Z1-638BJBEVM board, check to assure that the version is at least 10.2 or later. If
CodeWarrior has not been installed, the following steps describe the installation process.
1. Go to http://www.nxp.com and navigate to the CodeWarrior Development Tools site.
