Hello

I tried to use a Intel 82574 based miniPCIe NIC on a Freescale iMX6 eval board as shown below. It seems that the NIC is unable to read and/or write the descriptors in system memory. The settings of the PCIe core registers seems to be OK (according to the iMX6 RM).

Any idea what i am missing?
