• SD Card (2GB minimum)
• 5V Power supply
• microUSB cable

Preparing the Environment

Configure your Host PC - Serial Terminal

In order to communicate with the SABRE board and run the WLAN/BT demos, a serial port terminal program must be installed on your host PC. For Windows, you could use Teraterm or PuTTY. For Linux, we recommend Minicom.
Open PC's serial port terminal program and use the following settings:

Baud rate: 115200
Data : 8 bit
Parity: None
Stop: 1 bit
Flow control: none
Transmit delay msec/char: 1
Transmit delay msec/line: 1

Setup your SABRE board

This section will walk you through setting-up your SABRE board for use with the WiLink8 Demos:

• Plug the WL18xx SDIO Board into the SD2 port of the SABRE board, and connect provided "flat cable" between the adapter J13 FPC connector and SABRE J13 connector
  

SABRE setup Bottom view

SABRE setup Top view

   Important Note: when purchased the J13 port on the SABRE is not routed to the host processor. 
   In order to use J13, the resistors R209,210,211,212,213,214 and 215 need to populated on the SABRE board.

Addon Resistor location

   The adapter board comes with [default] jumpers assembly to work with a host.
   One exception: J10, J11 jumpers should be placed as in the picture below for the HCI UART CTS/RTS to function correctly with SABRE board.

J8, J10 Jumper Settings

• Plug the WL18xxMOD COM8 Kit into the WL18xx SDIO Board.
• Insert the SD card loaded with the latest image to the SD3 port of the SABRE board.
• Plug the USB cable into your host PC and plug it to the SABRE board USB port J509.
• Plug the 5V Power supply into the SABRE board power socket and power on the EVM.

Integration with Freesacale Linux BSP

To build and integrate the WiLink8 related software components into your own file system, you need to start by getting the official imx linux kernel source. The kernel source code is available at the following git:

git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git

fetching and building the imx kernel source code

1. create a working directory on you linux host 2. clone the git to this location 3. Checkout the release tag (currently rel_imx_3.14.28_1.0.0_ga)

mkdir ~/imx
cd ~/imx
git clone http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git
git checkout rel_imx_3.14.28_1.0.0_ga

Patching the kernel for WiLink8 build

The WiLink8 drivers are built out of tree using the build script provided here. These scripts now also provide the option to apply all the patched required to the i.Mx kernel to add WiLink8 Wifi and Bluetooth as well as patching the device tree files for the EVK and SABRE boards to enable them. So initial step is to download the script (step 1 on link) and then modify setup-env for your configuration (step 2). They key item here is to add KERNEL_VARIANT to setup-env in order to get the script to patch the rel_imx_3.14.28_1.0.0_ga release.

...
export KERNEL_VARIANT=imx-3.14.28
...

Next step is to apply the required patches to the kernel

./build_wl18xx.sh patch_kernel

Now the kernel can be built with these patches applied as follows from inside the kernel source directory:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make imx_v7_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make zImage modules dtbs

Installing build artifacts into the file system

Assuming your sdcard has two partions (boot and rootfs) and is mounted at /media/boot and /media/rootfs the following commands can be used to install all build artifacts into your sdcard:

• from the kernel source directory run the following command to install the kernel modules into your file system

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make modules_install INSTALL_MOD_PATH=/media/rootfs

• copy the zImage and .dtb file for the SABRE board to your boot partition

cp arch/arm/boot/zImage /media/boot
cp arch arm/boot/dts/imx6q-sabresd.dtb /media/boot

Building WiLink8 related artifacts

Now the kernel has been built the next stage is to do a full build of the WiLink8 related components using the build script. This is done by following step 3 (download code) and step 4 (build drivers) from WL18xx System Build Scripts page.

Installing WiLink8 build artifacts into the rootfs partition of your sdcard

Once a full ./build_wl18xx.sh has been completed, a tar file containing all build artifacts is created inside the outputs directory inside the build-utilites directory. This tar file is called fs_skeleton.tbz2
extract the content of this tar file on top of your rootfs sdcard partition. See the following example:

cd /media/rootfs
sudo tar xf ~/build-utilities/outputs/fs_skeleton.tbz2
depmod -a

Required Connection for HW Integration design

NOTE The connection is based on the i.MX Sabre board with MCIMX6Q6AVT10AC device

Following pin to pin connections are required in order to integrate smoothly WL8 TI module with IMX6Q device.

IMX6Q Line name	IMX6Q pin	WL8 module pin	WL8 Line name
KEY_ROW4	V5	51	HCI UART CTS
KEY_COL4	T6	50	HCI UART RTS
KEY_ROW1	U6	52	HCI UART TX
KEY_COL1	U7	53	HCI UART RX
KEY_ROW6	T1	41	BT EN
KEY_ROW0	V6	40	WL EN
KEY_COL0	W5	14	WL IRQ
SD2_DATA3	B22	13	WL SDIO D3
SD2_DATA2	A23	12	WL SDIO D2
SD2_DATA1	E20	11	WL SDIO D1
SD2_DATA0	A22	10	WL SDIO D0
SD2_CLK	C21	8	WL SDIO CLK
SD2_CMD	F19	6	WL SDIO CMD

Running the Demos

Boot the Board

To boot the board, simply apply power to the board by plugging in the 5V Power Supply. If the USB cable is plugged in and the serial port is configured correctly, you should see the output on your serial terminal(will take 1-2 min to load). You will see the board reach u-boot, and then automatically boot into the Linux kernel.

When prompted for a login, use root.

Demo Guide

The demos for both BT & WLAN is available on the main WL18xx page

make BUILD_TARGET_DEVICE=sd

Program the sabre platform SD Card with the updated android image that includes the wl18xx support

Note:The following sequence assumes that the android image is booting from SD Card Use the following sequence for updating the SD Card that is already running the standard L5.0.0_1.0.0-ga image:

• Power off the sabre platform and remove the SD Card mounted into the SD3 port
• Plug the SD Card into your Linux host and check its mount point (/dev/sd<x>) using mount
• Assuming the SD Card has been mounted as /dev/sdc use the below sequence to upate the system and boot images:

cd $OUT
sudo umount /dev/sdc1
sudo umount /dev/sdc5
sudo dd if=boot.img of=/dev/sdc1
sudo dd if=system.img of=/dev/sdc5
sync

• Eject the SD Card from the linux host
• Pluig the SD Card into the sabre platform SD3 port
• Power on the platform and wait for the android image to boot
• You should now be able to got into the settings page and enable wifi and bluetooth

export CROSS_COMPILE=${MYDROID}/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
export KERNEL_DIR=${YOUR_PATH}/kernel_imx/
export KLIB=${KERNEL_DIR}
export KLIB_BUILD=${KERNEL_DIR}
cd ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/
make defconfig-wl18xx
make

Installing the compiled modules into the android file system

The modules are installed into /system/lib/modules as part of the rebuild done below and are loaded from init.rc when the android image is booting

Building the final android image

Use the follwing seuence for rebuilding the android images that now includes all the added wl18xx releated components

cd $OUT
rm *.img

rm -fr root/
rm -fr recovery/
cd $MYDROID
make BUILD_TARGET_DEVICE=sd

Program the sabre platform SD Card with the updated android image that includes the wl18xx support

Note:The following sequence assumes that the android image is booting from SD Card Use the following sequence for updating the SD Card that is already running the standard L5.0.0_1.0.0-ga image:

• Power off the sabre platform and remove the SD Card mounted into the SD3 port
• Plug the SD Card into your Linux host and check its mount point (/dev/sd<x>) using mount
• Assuming the SD Card has been mounted as /dev/sdc use the below sequence to update the system and boot images:

cd $OUT
sudo umount /dev/sdc1
sudo umount /dev/sdc5
sudo dd if=boot.img of=/dev/sdc1
sudo dd if=system.img of=/dev/sdc5
sync

• Eject the SD Card from the linux host
• Plugthe SD Card into the sabre platform SD3 port
• Power on the platform and wait for the android image to boot
• You should now be able to go into the settings page and enable wifi
