I think the answer is no; but I can find little to nothing about it.
processor expert/Device initialization does not support any code generation for XGate.
We say “processor expert does not support any code generation for XGate”, for instance, processor expert can not be able to generate a prm file that include XGate associated content. So user has to rewrite their own xgate supporting prm file but can’t use pe generated prm.
Another example is that pe also can not generate xgate supported vector table, etc.
thus it loose some of the major advantages of pe.
This is the reason that if you make a project with XGATE the Proc.Exp. and Device initialization/processor expert option isn't enabled.
in practice, we don’t recommend user use processor expert and xgate together in one project. we only have sample code that use xgate or pe only but never use them together.
If you want take use of the processor expert tool generated code, please create pe project for generated the related driver code. then port the associated code to your xgate project.
