Hi,

                We are using imx6-q7 module with intel centrino advanced N 6235 wifi pcie module in our project and running in linux 3.0.35 kernel. As Intel 6235 module driver  supports from 3.2+ kernel, we have downloaded backport driver iwlwifi (3.10, 3.14) from link (http://wireless.kernel.org/en/users/Drivers/iwlwifi). While loading this driver we are unable to initialize the device. When we analyzing the logs we came to know that the driver tries to send firmware from DRAM to NIC - and NIC doesn’t receive data. 

 

iwlwifi 0000:07:00.0: L1 Disabled; Enabling L0S

iwlwifi 0000:07:00.0: Radio type=0x2-0x1-0x0

iwlwifi 0000:07:00.0: Failed to load firmware chunk!

iwlwifi 0000:07:00.0: Could not load the [0] uCode section

iwlwifi 0000:07:00.0: Failed to run INIT ucode: -110

iwlwifi 0000:07:00.0: Unable to initialize device.

 

I have attached detailed log  for your reference. Could you please help us to fix this issue.

 

Note:

While taking the attached log we have enabled debug=0xffffffff
