Windows XP Embedded: A build machine is required, with a copy of Microsoft Embedded Studio installed on it. 1. If a previous version of this driver has been used, delete the repository from under the "Windows Embedded Data" folder. To locate the exact folder to remove, browse in the "Repositories" subfolder. A number of folders will be present, each named with a GUID. These numbers are globally unique, so the exact folder name cannot be listed here, and the only way to identify the exact folder is to examine the contents. The folder in question will have six files: Gx2Prop.dll, Gx2WdmXe.inf, Gx2WdmAu.sld, Gx2WdmAu.sys, ks.inf, and wdmaudio.inf. Delete the entire folder, it will be replaced in a later step. 2. Import the component into Target Designer: - Copy the distribution files to a directory on the build machine. - Make sure that no tools in Embedded Studio are running. - Start the Component Database Manager, it should be running in Exclusive mode. Check the title bar to verify the words "(Exclusive Mode)" are present. - On the Database tab, press the "Import..." button. - Under "SLD File" enter the path to the distributed file "Gx2WdmAu.sld," the "..." button will open an "Open" dialog box. - Verify the checkbox "Copy Repository files to Repository Root" is checked. - Press the "Import" button at the bottom of the dialog. This should complete without error. The most common error is failing to remove an old repository, see step #1 above. - Close the Component Database Manager. 3. Add the component to a configuration: - Open an existing SLX file for the project. If one does not exist, one can be obtained for the Geode reference platforms from AMD. - Add the component by dragging "Advanced Micro Devices Geode Gx2 Audio Driver" from the catalog to the configuration. - Consider adding additional components, such as Media Player. -------------------------------------------------------------------------------- RELEASE HISTORY -------------------------------------------------------------------------------- Previous Version: N/A (Initial Release) Release Date: N/A (Initial Release) Dependencies ------------ - N/A (Initial Release) Functional Changes ------------------ - N/A (Initial Release) Defects Corrected ----------------- - N/A (Initial Release) Known Errata ------------ - N/A (Initial Release) ================================================================================ Copyright --------- © 2005 Advanced Micro Devices, Inc.
