Problem accessing the Port Logic Registers of PCIe Core when configured as RC.

Hi iMX communitiy.


We are creating a PCIe driver from scratch for the i.MX 6Solo (this because we need to give PCIe support to a proprietary RTOS). So we are just starting to experiment with the PCIe Core. We were trying to initialize the PCIe core (setting the clocks and setting the core as RC Mode, however we don't have any PCIe endpoint connected yet, we are just trying to setup the core).


The problem is that we are not able to access the Port Logic Registers. When trying to access them the system crashed.


What needs to be done in order to access the Port Logic Registers?. Are these registers accesible as normal memory registers?.


Thanks for your support.
