Finding PCI device QNXRTP

Hi all,

I want to look up a PCI device with QNXRTP (Neutrino) from the thing in the
program.
But, it is indicated with “Can not find device”.
VenderID and DeviceID are correct value.
What is bad?

#include <hw/pci.h>

#define PCI_VENDOR_ID 0x1264
#define PCI_DEVICE_ID 0x9
:
if( pci_find_device( PCI_DEVICE_ID, PCI_VENDOR_ID, pci_index, &busnum,
&devfuncnum ) != PCI_SUCCESS ) {
printf(“Can not find device\n”);
exit( EXIT_FAILURE );
}

Thanks,

I’m missing the initialisation of pci_index to 0 …

Two things:

  • You have to use pci_attach and pci_detach functions to be able to use
    any of the other pci_*() functions.
  • pci_index should be 0.
