lspci didn't show any device in i.mx6sl evk

[yyw1981]

I use Atheros AR9K in i.mx6sl evk with ltib which use linux 3.0.35.

I set CONFIG_PCI, CONFIG_IMX_PCIE enabled.

The lspci command can work but no pci device displayed.

Any patch file about pcie existed for i.mx6 solo evk?

Hi yan

i.MX6SoloLite has not PCIe module.

EVK has MINI PCI EXPRESS slot, it is used for some

WiFi cards which actually do not use PCIe.

Hi igor

Thank you for your reply.

I couldn't understand the means of "EVK has MINI PCI EXPRESS slot, it is used for some WiFi cards which actually do not use PCIe.".

I think EVK has mini PCIe slot, so it should be identified if a mini wifi pcie module be attached.

Hi yan

MINI PCI EXPRESS slot has also usb signals. They are used for some

WiFi cards made in mini PCIe connector form-factor.

Hi igor

Thank you for your reply. Do you mean the mini pcie slot in i.mx6sl evk only support usb signal and DO NOT support x1 PCI-E?

Both Mini PCI Express Form Factor and Express Card Form Factor support x1 PCI Express signals and USB and SMBus interfaces.

Any other form factor with the mini pcie slot in i.mx6sl evk?

Hi yan

yes, it is used for some mini PCIe form-factor cards like:

UHMC-GNB-AR-01 (ARS63-SB / ARS63-S)

802.11gn+BT Coexistence Wireless Module
