Good day, dear friends.

I am happy user of the qnx 6.4.0 operation system. Please, help me out. 

I think all people here  know about VME-to-PCI bridge that name Tundra Universe II.

My question is:

When we need to setup tundra window we must put into tundra service register address ( for example , LSI0_BS) of the pci
 memory that is aligned to 0x1000. In our project we define this address statically. For example,

#define	VMEA16_WIN_BASE	        0xA0000000

Of course this address must be free. Recently we ran into the situation when this address was allocated to other device 
and our system didn't work. Question is .............

How Can I get such address dynamically ??? Does qnx have mechanisms to send me this address ??? How Can I ask qnx os 
about next free address ( that have resolution of 4K ) in the pci memory???

Muchas gracias , amigos.
