The wl12xx driver is used by the Wi-Fi/Bluetooth chip present on the APF6 module. Before using the Wi-Fi, you have to calibrate the chip. This page details how to do it.

Installation

On APF6, all needed tools/drivers are installed by default. You can directly switch to calibration.

Linux

Be sure to have CONFIG_NL80211_TESTMODE enabled.

Networking support --->
 Wireless --->
  <*> cfg80211 - wireless configuration API
   [*] nl80211 testmode command

Buildroot

You need the calibrator tool from the ti-utils package.

Target package --->
 Hardware handling --->
  [*] ti-utils

Calibration

Note: Following instructions are only needed the first time after you flashed your rootfs.

To calibrate the chip use the S30wifi script with a MAC address

# /etc/init.d/S30wifi calibrate 00:1E:AC:00:51:22
Calibrating
wlcore: down
mmc0: card 0001 removed
sdhci-esdhc-imx 2190000.usdhc: card claims to support voltages below defined range

wlcore: loaded
wlcore: power up
wlcore: firmware booted in PLT mode PLT_ON (PLT 6.3.10.0.133)
wlcore: testmode cmd: radio status=0

The path to NVS file not provided, use default (/lib/firmware/ti-connectivity/wl1271-nvs.bin)
wlcore: power down
mmc0: card 0001 removed

Daily use

The WiFi is started automatically at boot thanks to the /etc/init.d/S30wifi script.

To stop the WiFi

# /etc/init.d/S30wifi stop
wlcore: down
mmc0: card 0001 removed

To start the Wifi

# /etc/init.d/S30wifi start

wlcore: loaded
wlcore: firmware booted (Rev 6.3.10.0.133)
IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

Going further

Now you can use the general instructions here to setup your Wi-Fi network (as client/station (STA)).
If you want to use your APF board as an access point then take a look at APF as Wi-Fi Access Point (AP).
It should be possible to use this chip in Multi-Role (STA+AP), but currently we have a firmware reboot problem when following [1]. If anyone knows how to proceed, please send us an email or join us on IRC ;-).

Tips

To have more debug messages of firmware loading/boot process, one may load drivers this way:

# modprobe wlcore debug_level=4; modprobe wl12xx; modprobe wlcore_sdio
