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.
