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.
