iMX6 Dual - Bug PCIe with i210 device

Hi,

I designed a board with an iMX6 Dual processor. On the PCI express, I linked an I210-IT ( Intel Ethernet Controller PCIe v2.1 2.5GT/s).

|------------------|                                               |------------------|

|   iMX6D        |                                              |    I210-IT       |

|            Clk1   | --------------||-------------------->| PCE_Clk      |

|       PCIe TX | ---------------||-------------------->| PCE RX       |

|       PCIe Rx |<--------------||----------------------| PCE TX       |

| -----------------|                                               |------------------|

 

For the reference Clock PCIE, I used the output CLK1_P/N to synchronize I210 RefClock. Is it correct or wrong?

 

I used linux issue YOCTO version 4.1.15_1.0.0.

 

Sometimes, PCIe  bugs to the READ access and more rarely, to the WRITE access. Have you any suggestions about this problem?

 

Sincerely,

Michel
