Add Wi-Fi support to Freescale i.MX6Q based platforms

This page provide short information on how to build and install the HDG200 wifi driver on different linux platforms. Pre-built images can be found here.

Build HDG200 R2 driver

In the following we assume that the target platform is imx6qsabresd (i.e. MCIMX6Q-SDB). To build for another platform, simply replace all instances of imx6qsabresd to your-platform.

1. Ensure linux kernel configs according to defconfig-hdg200-r2.cfg are set!
2. Unpack
   $ tar -xvzf nrx900-1.0.5.tar.gz
3. Config
   $ echo "COMPONENTS := wifi sdio" > .../nrx900/driver/linux/platform/imx6qsabresd.mk
   $ echo "D+=NRX_CONFIG_SDIO_HS" >> .../nrx900/driver/linux/platform/imx6qsabresd.mk
4. Build
   $ cd nrx900/driver/linux
   $ make PLATFORM=imx6qsabresd KERNEL_DIR=/path/to/kernel ARCH=arm CROSS_COMPILE=/path/to/prefix all
   $ make PLATFORM=imx6qsabresd KERNEL_DIR=/path/to/kernel ARCH=arm CROSS_COMPILE=/path/to/prefix INSTALL_MOD_PATH=/path/to/rootfs modules_install
5. Install firmware
   $ install -D nrx900/firmware/x_mac/GENERATED-FILES/nrx2b_chip_patch/patch.fw <INSTALL_MOD_PATH>/lib/firmware/nanoradio/nrx900_wifi.fw

Use HDG200 R2

1. Insert HDG200 SDIO card into target
2. Load kernel module
   # modprobe nrx
