PCIe wifi card(iwl4965) not working on IMX6q sabre-sd board.

[hanseunglee]

I use LTIB system. not YOCTO.

In my case, to do below.

1. ltib$./ltib -m config

     - check Always rebuild the kernel

     - check Configure the kernel

     save and exit

2.  ltib$./ltib

     .config - Linux kernel Configuration

     -  System Type enter

          - Freescale MXC Implementations enter

               - chkeck PCI Express support

     - Bus support enter

          - check Message Signaled Interrupts(MSI and MSI- X)

          - check PCI Express support

     - Networking support enter

          - wireless enter

               - check Generic IEEE 802.11 Networking Stack(mac80211)

     - Device Drivers

          - check Network device support

               - Wireless LAN enter

                    - check iwl 4965

save end exit

I try change tar rootfs.bz2 on the linux and then copy to sabre-sd board for insert wifi card(iwl4965.ko) driver. But it also not working.

That is  all when I ready for PCIe wifi card install. But I could not success install driver(can not run on imx6q -sabresd board)

If you have a solution, please tell me.

Hi Hanseung

for configuration one can look at attached patches (L3.0.35_4.1.0)

and Linux Manual sect.35.4 Using PCIe Endpoint and running Tests.

Also check that uart5 is not enabled (it conflicts with PCIe) :

iwl4965 firmware

Hi igor!

I really appreciate for your reply.

But I can not solve the problem.

I did check your attached patches.

1. uart5 check in circuit. it's ok.

2.

In my case,

-- in the board

root@freescale ~$ lspci

00:00.0 Class 0604: 16c3:abcd

01:00.0 Class 0280: 8086:4229

anything not work.

root@freescale /lib/firmware$ ls

Android.mk                ar3k                      sdma

LICENCE.atheros_firmware  ath6k                     vpu

README                    iwlwifi-4965-2.ucode

lib/firmware on the driver.

How to get the driver ? use lspci cmd.
