Hi igorpadykov ,

     I checked board and found  700-27142-REVX4  & SCH-27142-REV B1 . May be i am using older version board.  But i have another board with 700-27142-REV A & SCH-27142-REV C.  Will this board support pcie.

REV A in "700-27142-REV A" is cofusing !!

"700-27142-REV A" is assembly revision, not board revision.

Hi igor ,

                  Thank you very much for your quick responce. I am trying to enable pcie. I am trying this on i.Mx6Q sabreauto with SCH-27142-REV C.

As i have browsed on forum and found that this board should support pcie.  But i am getting following error!!

iMX6 PCIe PCIe RC mode imx_pcie_pltfm_probe entering.

PCIE: imx_pcie_pltfm_probe start link up.

link up failed, DB_R0:0x001f3e00, DB_R1:0x08200000!

IMX PCIe port: link down!

I have used L3.0.35_4.1.0_130816_source.tar.gz. pcie device is of Atheros. 

what could be the possible reason for this issue?
