The Rolling Cumulative Patch Layer (RCPL) was developed by Wind River to      simplify patch management of Wind River Linux.  The expected usage   is    that customers install the latest RCPL for their release.  Base   Wind    River Linux 6.0 + RCPL is the default supported configuration.    Please    install this RCPL at your earliest convenience.
The README.txt on this OLS page contains instructions on how to use      these features, general information on the RCPL and a complete list of      defects fixed. Conversely, the defects listed in OLS page aren't      complete due to the length limitation of characters. The README.txt      should be reviewed prior to installation.
The whatsnew file on the OLS page contains what new features were added by each RCPL.

Requires Wind River Linux 6.0 to be installed
Wind River Linux 6.0.0.12 is now only available via Electronic Software Distribution (ESD) method accessible via the Wind River Installation Tool (wrInstaller) available within your product installation.
Step 1 - Prepare
Step 2 - Install
NOTE - 1) If you're having connectivity (firewall or network setup) issues, Wind River allows you to run the wrInstaller on a machine with Internet connectivity by downloading this update pack into a convenient location and then installing the content back onto the development machine. Follow these instructions:
2) On Windows hosts, you may notice some errors in the "setup.log" around "readlink" and "uninstall_mgr.sh". These messages can be ignored as they do not affect the running of the product. If though you should decide to un-install the product, there may be some error messages about changed files which the Installer will not remove. In this case, you can simply remove the remaining files and the installation directory manually.
