Hi all,


I am testing iwl4965 on mini pcie port of MX6Q SABRESD. After linux boot, I can see noting using 'lspci',and I find these messages during boot up:



iMX6 PCIe PCIe RC mode imx_pcie_pltfm_probe entering.

PCIE: imx_pcie_pltfm_probe start link up.

link up failed, DB_R0:0x002f0200, DB_R1:0x08200000!

IMX PCIe port: link down!

IMX usb wakeup probe



My BSP is  L3.0.35_4.1.0_130816 downloaded from freescale,and I add support of pcie in kernel:

System Type  --->Freescale MXC Implementations  --->[*] PCI Express support

Bus support  --->  PCI Express support

Device Drivers  ---> Network device support --->Wireless LAN ---> <*> Intel Wireless WiFi 4965AGN (iwl4965)


Adding EC and RC support have no help.


Anyone knows the reason? Are there some places I need pay attention to?

Thanks in advance!
