Dear All,
>
> I have developed x86 PCI driver on vxWorks-5.4. Now I want to port x86 PCI device driver on vxWorks-6.3. In x86, after getting the physical address for my device we add the device address space to the MMU table using "sysMmuMapAdd()" and "usrMmuInit()".


> But in vxWorks-6.3 "sysMmuMapAdd()" function is getting passsed at runtime but I am getting "PAGE FAULT" at the time of execution of "usrMmuInit()" function (at run time).


> Please guide how can i map Memory without any errors and to solve this problem.



> Thanks and regards,
