iMX6Q - PCIe

iMX6Q - PCIe

[John Tobias]

Hi All,

I am trying to use the PCIe on iMX6Q and I am using kernel 3.15.2 and
AEH-AR9462-LC WFI-BT module.

The said module were able to detect by the kernel, able to bring up
the wifi and bluetooth interface and able to scan bluetooth devices as
as scan wifi.

When, I run /usr/sbin/wpa_supplicant -Dnl80211 -iwlp1s0
-c/tmp/wpa_supplicant.conf, I got the following logs (please see
below). The wpa supplicant keeps trying to connect but for unknown
reason, it keeps disconnecting.


Any idea?.

Regards,

john

you can try to disable MSI (at least that's how I got ath9k working in
FSL's kernel)

Hi Eric,

I have a few questions:

1. May I know what FSL's kernel version you are using?.
2. Did you make changes in your device tree for PCIe?.
3. Can I have the model/part # of your ath9k?.

Regards,

john

was 3.0.35 + backport from 3.14 for 802.11 + ath9k from
http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/

> 2. Did you make changes in your device tree for PCIe?.
no DT on this kernel

tested with Mikrotik R11E & Ubiquiti SR71

Hi Eric,

Thanks for the info.

I tested 3 PCIe modules and one of them got working properly on kernel
3.15.2 and the fsl kernel 3.10.17.

john
