PCI interface in imx6 saberauto board not working

Contributor I

I am trying to connect Atheros Wifi chip to PCI-E interface of imx6 saberauto board but it's is not working.

After analyzing the boot logs ,  i found that PCI-E link is down.

I am not able to figure it out why i am PCI-E link down error.

Attached is the boot logs.


I have already enabled all  the drivers required for PCI-E interface using LTIB.

Did you solve the PCI issue ? I also have a same problem.

In my case, to do below.

1. ltib$./ltib -m config

     - check Always rebuild the kernel

     - check Configure the kernel

     save and exit

2.  ltib$./ltib

     .config - Linux kernel Configuration

     -  System Type enter

          - Freescale MXC Implementations enter

               - chkeck PCI Express support

     - Bus support enter

          - check Message Signaled Interrupts(MSI and MSI- X)

          - check PCI Express support

     - Networking support enter

          - wireless enter

               - check Generic IEEE 802.11 Networking Stack(mac80211)

     - Device Drivers

          - check Network device support

               - Wireless LAN enter

                    - check Atheros Wireless Cards

                         -  Atheros 802.11n wireless cards support (just my case)

save end exit

That is  all when I ready for PCIe wifi card install. But I could not success install driver(can not run on imx6q -sabresd board)

If you have a solution, please tell me.
