I have a custom IMX6Q board in which I am not able to get PCIe up. I am using LTIB environment.
I have looked into other posts regarding the clock enable in RC mode, which seems to be enabled linux-3.0.35. I am trying to connect a dual port NIC card from Intel (0G174P) which is supported by the igb driver in kernel.
I always get this error during the kernel boot.
iMX6 PCIe PCIe RC mode imx_pcie_pltfm_probe entering.
PCIE: imx_pcie_pltfm_probe start link up.
link up failed, DB_R0:0x00d5f700, DB_R1:0x08200000!
IMX PCIe port: link down!
I had initially only connected PCIe RX, TX and CLK (driven by IMX6). I tried connecting a GPIO for PCI_Reset but that didn't help my cause.
Can you please suggest me what should I do next in order to get PCIe interface checked out?
