How to Configure EWF for CompactFlash (Windows Embedded Standard 2009)


CompactFlash devices are write-sensitive and have a limited number of write cycles. Adding the Enhanced Write Filter (EWF) component to your run-time image prolongs the lifespan of your CompactFlash device by intercepting and storing write requests. For more information, see Enhanced Write Filter.

A CompactFlash run-time image is configured at the end of the development cycle, when a run-time image is ready to be deployed.

The following table shows the steps required to configure EWF for CompactFlash.

3. Prepare the CompactFlash Device.

4. Configure your run-time image to support EWF RAM Reg Mode and deploy it to the CompactFlash device.

Running FBA directly on the CompactFlash device can be time consuming and write-intensive. You can deploy your run-time image to a hard disk to run FBA, then copy the post-FBA run-time image to the CompactFlash device.
