How to Configure and Build an OS Image for a CEPC
Before building an OS image for a CEPC, you may need to change settings in the Platform Builder IDE to configure your platform for your CEPC hardware requirements and your development goals. If you use a full-featured or a debug configuration, configure your platform to reside in a larger amount of RAM than the default amount of 28 megabytes (MB) specified the Config.bib file. If you want to support kernel debugging, profiling, or other build options, you must specify these options in the IDE.
Hardware and Software Assumptions
- You have set up a CEPC. For more information, see How to Set Up a CEPC.
To track your progress in the following table, select the check box next to each step.
|1. Use the Platform Wizard to select a configuration and the initial components for your platform.
For more information about the platform creation process, see Platform Creation with the New Platform Wizard.

|2. Customize your platform by selecting additional features from the Catalog or deleting features from your platform.||Adding a Feature from the Catalog|
|3. Configure settings for your platform based on your development goals.
For more information about platform settings you can configure, see Platform Settings.

|4. Check the dependencies of the features in your platform.

|5. Modify the MEMORY section in the Config.bib file by setting the environment variable that specifies the amount of RAM on your CEPC hardware, or the amount of RAM you want to simulate.
By default, the Config.bib file specifies 28 MB of RAM, and then OAL scans for additional memory at run-time, for up to a total of 64 MB.
For information about adding support for more than 64 MB of RAM, see Supporting or Simulating More than 64 MB of RAM.
