Preparing the Environment

Setup your SAMA5D2-Xplained platform with the WL18XX based module

This section will walk you through setting-up your SAMA5D2-Xplained platform for use with the WL18XX based module, which is connected using the SDMMC1 port:

• Plug the WL18xx SDIO Board into the SDMMC1 port of the SAMAD52-Xplained platform.
  

The adapter board comes with [default] jumpers assembly to work with a host.

• Plug the WL18xxMOD COM8 Kit into the WL18xx SDIO Board.
• Connect a wire used as GPIO for controlling the WL18xx WLAN_Enable between pin 2 of the J12 (WL_EN_COM) of the WL18xxMOD COM8 Kit, and J22 pin 15 (PA23) on the SAMA5D2 platform.
• Connect a wire used for interrupts gpio from the WL18XX chip (WL_IRQ) WL18xx between pin 1 of J19 (HOST_WL_IRQ_3V3) of the WL18xxMOD COM8 Kit, and J22 pin 14 (PA24) on the SAMA5D2 platform.

See pictures of the connected platforms below:

Integration with the linux4sam 4.1 based Linux kernel

fetching and the kernel source code

To build and integrate the WiLink8 related software components into your own file system, you need to start by getting the Linux4SAM kernel source code.
Please refer to the Getting Kernel sources link.
Follow the instructions for cloning the kernel git and checking out the linux-4.1-at91 branch

Patching the kernel for WiLink8 build

The WiLink8 drivers are built out of tree using the build script provided here.
These build scripts also provide the option to apply the patches required on top of the linux-at91 kernel, for adding WiLink8 WLAN support.
The initial step is to download the script (step 1 on link) and then modify setup-env for your configuration (step 2).
One key item here is to add KERNEL_VARIANT to setup-env in order to get the script to patch the linux-4.1-at91 kernel branch with the additions needed for the wilink8 integration.

...
export KERNEL_VARIANT=linux-4.1-at91
...

Next step is to apply the required patches to the kernel

./build_wl18xx.sh patch_kernel

Once you have run the above command, the kernel can now be built with these patches applied.

Building the updated kernel and device tree file

Important Note: Before building the kernel make sure the following modules will not be built intree.
Edit the ".config" file after running "make ARCH=arm sama5_defconfig" but before you build the kernel:

# CONFIG_CFG80211 is not set
# CONFIG_MAC80211 is not set

Use the method described in Configure and Build section.
Once the kernel and device tree builds are completed, you need to use the updated arch/arm/boot/zImage and arch/arm/boot/dts/at91-sama5d2_xplained.dtb.

Building WiLink8 related artifacts

Now that 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 and step 4 from the WL18xx System Build Scripts page.

Important Note: When using the build-script for building with the linux-at91 4.1 kernel, you may see a build failure during the wl18xx drivers build.
This is due to a redundant backports patch that breaks the drivers build with this kernel and can be deleted
In case this happen, you need to remove this patch and run the script again (with no parameters this time), in order to complete the build.
See the sequence below that should be used in case of failure during the build script build:

rm src/backports/patches/collateral-evolutions/network/0053-possible_net_t.patch
./build-wl18xx.sh

Booting the platform using the updated zImage and device tree file at91-sama5d2_xplained.dtb

By default, when powering up the platform, the kernel and device tree files are already present inside the nand flash of the target. The defualt boot command is copying them from NAND to ram and using them for boot.
You can use the following command to tftp the kernel and device tree file and use them for boot instead of the ones that are inside the flash already.

U-Boot> setenv bootcmd_tftp "tftp 0x22000000 zImage; tftp 0x21000000 at91-sama5d2_xplained.dtb; bootz 0x22000000 - 0x21000000"
U-Boot> run bootcmd_tftp

Note: once you are satisfied with the updated kernel and device tree file you can use u-boot for updating the kernel and device tree in the platform nand flash.

Installing WiLink8 build artifacts into the platform root file system

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

Follow the following steps for installing this tar file into the internal flash file system of the platform:

• boot the board and connect it to your network using an Ethernet cable.
• Use tftp for downloading the "fs_skeleton.tbz2" to your platform.
• Extract the tar file on top of the root directory of your file system.
  

See the example below:

tftp -g -r fs_skeleton.tbz2 <tftp_server_ip>
tar xf ./fs_skeleton.tbz2 -C /
depmod -a
reboot

Running the Demos

Boot the Board

Power up the platform and use the commands above for booting the platform using the kernel and device tree file downloaded using tftp.
In case the updated kernel and device tree file were used, during boot you should see an SDIO module being detected:

mmc1: queuing unknown CIS tuple 0x91 (3 bytes)
mmc1: new high speed SDIO card at address 0001

and next you should see the wl18xx driver loading:

bring up the wlan0 interface, connect and ping

Use the following basic sequence for bringing up the wlan0, connecting to an open AP, dhcp and ping:

ifconfig wlan0 up
iw wlan0 scan | grep SSID
iw wlan0 connect <open_ap_ssid>
udhcpc -i wlan0
ping <ap_ip>

Expected output:
