WL18xx First Time Getting Started Guide (Hawthorn)
Contents
Hardware[edit]
The following componets are used for this demo setup:
- Hawthorn development platform with the wl18xx module mounted
- TI WiLink™ WL18xx WLAN SDIO/BT UART adapter Board: wl18xxcom82sdmmc Adapter kit
- TI - WL1835MOD COM8 Kit ,* or TI WL1837MOD COM8 Kit
Preparing the Environment[edit]
Setup your Hawthorn platform with the WL18XX based module[edit]
This section will walk you through setting-up your Hawthorn platform for use with the WL18xx based module, which is connected using the SD Connecion/SDIO Slot port of the Hawthorn board
- Plug the WL18xx SDIO Board into the SD Connecion/SDIO Slot port of the Hawthron platform.
The adapter board comes with default jumper assembly to work with a host.
- Plug the WL18xxMOD COM8 Kit into the WL18xx SDIO Board.
- Connect a wire used for interrupts from the WL18XX chip (WL_IRQ) WL18xx between pin 1 of J19 (HOST_WL_IRQ_3V3) of the WL18xxMOD COM8 Kit, and GPIO14 on the Hawthorn platform (the 15th pin from the left in the picture below).
Integration with the Ambarella s2l_purelinux_sdk_2_6[edit]
Getting the kernel Ambarella BSP[edit]
To build and integrate the WiLink8 related software components into your own file system, you need to start by getting the Ambarella SDK source code directly from Ambarella. Follow the SDK instructions for setting up you build environment.
Patching the kernel for WiLink8 build[edit]
The WiLink8 drivers are built out of tree using the build scripts provided here. The initial step is to download the script (step 1 on link) and then modify setup-env for your configuration (step 2).
Updating the Hawthorn device tree file for adding wl8xx support[edit]
This is the device tree file required: (hawthorn.dts)
It is derived from the original file that is part of the ambarella BSP: …/s2l_purelinux_sdk2_6/ambarella/boards/hawthorn/bsp/hawthorn.dts The difference is the addition of wilink8 WLAN support into this file.
Updating the kernel defconfig file[edit]
In the default defconfig: …/s2l_purelinux_sdk2_6/ambarella/boards/hawthorn/config/kernel/hathorn_xxx_defcnfig
The following switch is not selected:
CONFIG_CRYPTO_GCM is not set
Please make sure it is selected:
CONFIG_CRYPTO_GCM=y
Building the updated kernel and device tree file[edit]
Build the updated .dts file and kernel (zImage) using the SDK build instructions
[edit]
Next step 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.
Note: When setting the build script “setup-env” use the below settings for pointing the build script to the location of the hawthorn “kernel” and root filesystem (fakeroot):
export ROOTFS=<your_prefix>/Ambarella/S2L_IPCAM/SDK2.6/Pure_Linux/s2l_purelinux_sdk2_6/ambarella/out/hawthorn/fakeroot export KERNEL_PATH=<your_prefix>/Ambarella/S2L_IPCAM/SDK2.6/Pure_Linux/s2l_purelinux_sdk2_6/ambarella/out/hawthorn/kernel/linux-3.10_s2l
Setting the ROOTFS to your fakeroot directory allow the build script to install all the build output (wl18xx modules, wpa_supplicant/firmware etc.) directly into the file system used with the target.
Running the Demos[edit]
Boot the Board[edit]
Power up the platform and let the system boot up. In case the updated kernel and device tree file were used, during boot you should see an SDIO module being detected:

and next you should see the wl18xx drivers loading:
