Per-BSP confdefs (or resource allocation)

[Isaac Gutekunst]

Let me clarify. I don't think I explained my predicament very well.


None of the tests will run because the base application for our BSP requires resources that 
aren't available.

On the application side we're fine.

We have a couple of applications running correctly, by specifying configuration in the main C 
file using the standard method (#defining options and including condefs.h).

Is there any hackish way to setup the tests to allocate more resources?
