We have an existing VxWorks 5.5 project and want to port it to VxWorks 6.6.
VxWorks 6.x has a bunch of new capabilities (MMU, RTPs, etc...) which we don't want to use at this point since it would complicate the porting effort.
How do we specify that we want a 5.5 compatible environment?
When you create your VxWorks project, you can specify the PROFILE_COMPATIBLE which creates a 5.5 compatible environment.
In workbench, this is done in the new project creation dialog. It is the 3rd or 4th dialog screen titled "Configuration Profile"
When creating a project from the command line with vxprj, simply add a "-profile PROFILE_COMPATIBLE" parameter.
