Hi all,
we have a mpc8555 custom based board, we connected a pci to usb bridge(32 bit, 33MHZ,PCI1) on it thru IDSEL18.
we are not able to get the vendor and device id of the chip when we are doing configuration address reg write.
it seems all transactions are correct(pci_frame,idsel,irdy,trdy etc..).
what is the basic configuration required to read the chip configuration.
