Step-by-step: How to setup TI Wilink (WL18xx) with iMX6 Linux 3.10.53

[erezsteinberg]

Hello everyone,

I'm sharing my experience bringing-up a TI Wilink Module (WL18xx) on iMX6 Linux 3.10.53

You can find a lot of information here: WL18xx - Texas Instruments Wiki

And iMX6 instructions here- WL18xx First Time Getting Started Guide (IMX6) - Texas Instruments Wiki

Hardware setup -- iMX6 communicates with WL18xx over SDIO (WiFI) and UART (Bluetooth).

On iMX6, the tricky part is correct connection of the UART lines, especially the RTS/CTS lines.

In DCE mode (default) the signals should be connected as follows:

     WL18xx Module                         iMX6 Port

    [Out] Pad 50 (BT_HCI_RTS)   ---->       UART_RTS

    [In ] Pad 51 (BT_HCI_CTS)   <----       UART_CTS

    [Out] Pad 52 (BT_HCI_TX)    ---->       UART_RX

    [In ] Pad 53 (BT_HCI_RX)    <----       UART_TX

If the RTS/CTS lines are connected incorrectly, the BT driver won't be able to load.

Software setup-

You should have Linux 3.10.53 and a Root file-system ready.

(Make sure you don't have any uncommitted changes)

To build the WiFi drivers, follow the steps in WL18xx System Build Scripts - Texas Instruments Wiki

In the setup-env file :

TOOLCHAIN_PATH    -- Either use your iMX6 toolchain, or leave as default (it worked for me).

ROOTFS                     -- Point to your root filesystem

KERNEL_PATH           -- Point to you Linux kernel sources

KERNEL_VARIANT     -- Set to 'imx-3.10.53'  (This will apply patches to your kernel !)

Steps to build the WL18xx software:

git clone git://git.ti.com/wilink8-wlan/build-utilites.git

cd build-utilites/

cp setup-env.sample setup-env

<edit setup-env>

./build_wl18xx.sh init          (This will take a long time)

./build_wl18xx.sh patch_kernel

The last step applies several patch to your kernel. The patches include updates to the sources files, configuration files, and device tree files.

If you use a different kernel configuration than imx_v7_defconfig, make sure to make the same kernel changes to your configuration.

Also, update your device tree files according to the patches.

In your device tree, make sure to setup the BT_EN_SOC, WLAN_EN_SOC, and WL_IRQ GPIOs correctly, and provide them in the correct nodes in the device tree.

Here's an example -

    // BT and WiFI Enable [OUT]

    MX6QDL_PAD_EIM_D16__GPIO3_IO16  0x13059   // BT_EN_SOC

    MX6QDL_PAD_EIM_D17__GPIO3_IO17  0x13059   // WLAN_EN_SOC

    MX6QDL_PAD_SD3_DAT4__GPIO7_IO01 0x13059   // WL_IRQ

    wlan_en_reg: fixedregulator@2 {

        compatible = "regulator-fixed";

        regulator-name = "wlan-en-regulator";

        regulator-min-microvolt = <1800000>;

        regulator-max-microvolt = <1800000>;

        /* WLAN_EN GPIO for this board – Bank4, pin7 */

        gpio = <&gpio3 17 0>;

        /* WLAN card specific delay */

        startup-delay-us = <70000>;

        enable-active-high;

    };

    kim {

            compatible = "kim";

            nshutdown_gpio = <80>;  /* GPIO3_IO16 */

            dev_name = "/dev/ttymxc2";

            flow_cntrl = <1>;

            baud_rate = <3000000>;

    };

    btwilink {

            compatible = "btwilink";

    };

&usdhc3 {

    pinctrl-names = "default";

    pinctrl-0 = <&pinctrl_usdhc3>;

    no-1-8-v;

    keep-power-in-suspend;

    enable-sdio-wakeup;

    vmmc-supply = <&wlan_en_reg>;

    non-removable;    /* non-removable is not a variable, the fact it is */

                      /* listed is all that is used by driver  */

    cap-power-off-card;

    status = "okay";

    #address-cells = <1>;

    #size-cells = <0>;

    wlcore: wlcore@0 {

        compatible = "ti,wlcore";

        reg = <2>;

        interrupt-parent = <&gpio7>;

        interrupts = <1 0>;

        platform-quirks = <1>;

    };   

};   

&uart3 {

    pinctrl-names = "default";

    pinctrl-0 = <&pinctrl_uart3>;

    status = "okay";

    /* enable rts/cts usage on uart3 */

    fsl,uart-has-rtscts;   

};

Now -- build you kernel -

   make -j4 uImage modules dtbs

Install the modules in your root filesystem

    make modules_install INSTALL_MOD_PATH=<rootfs path>

Now, run the last step in the Wilink build script:

./sudo_build_wl18xx.sh update R8.5

This will build and install the Wilink drivers and software in the root filesystem.

That's it! -- it should work.   The wifi modules should load automatically when the kernel boots.

How to test?

WIFI -

>   ifconfig wlan0 up

>   iw wlan0 scan

(This should display a list of access points).

Bluetooth -

>    hciconfig hci0 up

>    hcitool scan

(This should scan for bluetooth devices).

Additional comments-

1. You can also use Linux 3.14.28, but you'll have to apply the patches manually.

2. If you have an issue with RTS/CTS, you can disable it. :

  (a) Change flow_cntrl to <0> in kim.

  (b) Change the baud rate to 115200 in kim.

  (c) Remove  fsl,uart-has-rtscts;   in the uart node.

  (d) Remove the CTS and RTS in the IOMUX

  (e) Comment out line 208 in src/uim/uim.c (in the build-utilites folder)

         ti.c_cflag |= CRTSCTS;

   NOTE 1: Without RTS/CTS you must bring up the Bluetooth driver first

   NOTE 2: You really should use RTS/CTS -- otherwise expect problems due to sync lost between host and module.

Good luck!

Hi Dave

I have brief experience to build the WiFi drivers for wl1837 for my Linux kernel 3.13.9

Maybe it will be useful

There is a link: https://e2e.ti.com/support/wireless-connectivity/wifi/f/968/t/819135 

best regards

[jasonl]

I believe this is for WiLink7 right? Is there any device tree instruction for WiLink8? Thanks.

[danielbujak]

Is there support for later versions of the kernel for this? I'm on 4.1.15 and don't see a patch directory for it.

[khangbui]

I can’t figure out what to map the BT_EN_SOC, WLAN_EN_SOC, and WL_IRQ  GPIOS to for the i.MX6 Solo X. Any
help would be greatly appreciated!

[ivannikolaenko]

Hello Khang Bui

You have to reserve this pins in the device tree like this at first:

     MX6QDL_PAD_EIM_D16__GPIO3_IO16  0x13059   // BT_EN_SOC

     MX6QDL_PAD_EIM_D17__GPIO3_IO17  0x13059   // WLAN_EN_SOC

     MX6QDL_PAD_SD3_DAT4__GPIO7_IO01 0x13059   // WL_IRQ

BT_EN_SOC is used in "kim" node, it is "nshutdown_gpio = <80>;  /* GPIO3_IO16 */"

(3-1)*32 + 16 = 80 - it is an order number of gpio3_16 pin.

WLAN_EN_SOC is used in "wlan_en_reg: fixedregulator" node, it is "gpio = <&gpio3 17 0>;"

<&gpio3 17 0> is "gpio bank 3", "gpio3 pin 17", "ENABLE_ACTIVE_HIGH (0)"

WL_IRQ is used in the "wlcore: wlcore@0" node, it is

        "interrupt-parent = <&gpio7>;

        interrupts = <1 0>;"

You can read about interrupts in the Documentation/devicetree directory.

Best regards,

Ivan

[khangbui]

Ivan,

Do you have an example of implementing the device tree for the Solo X? It looks like the quad uses uart4, I'm assuming the SoloX uses uart5 correct? An example would help me out a lot in figuring out the differences between that the quad device tree and the solox device tree for this TI driver. Thanks!

[ivannikolaenko]

Devicetrees of quad and solo differs, by and large, only in #include "imx6q.dtsi" string. For solo it will be #include "imx6sl.dtsi".

As of the UART's: see "aliases" node in your .dts or .dtsi file. UART5 is the /dev/ ttymxc4 device in the Linux, because Linux devices starts from 0, not the 1.

[khangbui]

Ivan, Thanks that's really helpful! Is this the case for the solox as well? I only ask because there's a seperate dts/dtsi file for it seperate from the solo.

[ivannikolaenko]

I guess that for SoloX you have to use imx6sx.dtsi and for SoloLite imx6sl.dtsi instead.

Hi Erez,

I have applied patch to the BSP 3.10.53 but having compilation error when i try to compile the modules.

The log file is attached. Any input is much appreciated.

When I do "lsmod" I see a compat and wlcore_sdio modules loaded.

I successfully load a missing modules cfg80211, mac80211, wlcore and wl18xx and nothing happened.

ifconfig wlan0 up

ifconfig: SIOCGIFFLAGS: No such device

/usr/sbin/wlconf script changes nothing.

BT_EN pin also low and hciconfig falling with timeout.

Have you encountered such problems?

Hi All,

I am using Jorjin WG7831D0 Wi-BT combo module and trying to support on i.Mx6 with linux kernel 3.10.53.

I have referred above post to backport the wl18xx driver to linux 3.10.53

We have configured WLAN_EN, BT_EN and WL_IRQ as per the link.  I am able to build successfully.

But during boot,

But We are getting following messages while booting:

Checked lsmod and only compat.ko and wlcore_sdio.ko getting loaded. We tried to manually insert wlcore,cfg80211,mac80211 and  wl188x drivers.

But wlan0 is not listing in iwconfig.

If I try rfkill list, only hci0 is listing.

even bluetooth init is failing

Let me know if I am missing anything.  I saw that Similar error message faced by Ivan too. How it is resolved?

Hi Ivan,

It would be helpful if you can also send the relevant parts in the device tree.

I'm running with Linux 3.14.28, so maybe there are some differences in the output.

First -- UIM is for Bluetooth.

On my port, the SYSFS Node is /sys/./devices/soc0/kim.15/install

Not sure why kim appears under the regulator node in your case (Suggest you check the device tree).

Also, when I build I issue the command:

./sudo_build_wl18xx.sh update R8.5

R8.6 is a new release -- See details WiLink8 Release Notes/R8.6 - Texas Instruments Wiki

Seems to be only for Linux 3.14.26+ ...

Try R8.5

Hi Erez!

I cleaned "wl8-build" directory and did as you advised, ./sudo_build_wl18xx.sh update R8.5

All compiled successfuly, but I got this message when modules were compiling:

Apply patches ...

However, alll modules loaded successful.

But when I tried to test wlan, I got:

root@~# ifconfig wlan0 up

ifconfig: SIOCSIFFLAGS: Operation not possible due to RF-kill

root@~# rfkill unblock all

root@~# wlcore: ERROR timeout waiting for the hardware to complete initialization

wlcore: ERROR timeout waiting for the hardware to complete initialization

wlcore: ERROR timeout waiting for the hardware to complete initialization

wlcore: ERROR firmware boot failed despite 3 retries

Can you suggest what causes it?

Hi Everyone!

Wi-Fi works after the following manipulations:

1. Delete all firmware from /lib/firmware/ti-connectivity at your target

2. ./sudo_build_wl18xx.sh update R8.5

    After that you will get two files in /lib/firmware/ti-connectivity: wl1271-nvs.bin and wl18xx-fw-4.bin

    At this step I had my WiFi working, but  I got this messages while booting:

     wl18xx_driver wl18xx.0.auto: Direct firmware load failed with error -2

     wl18xx_driver wl18xx.0.auto: Falling back to user helper

     wlcore: ERROR could not get configuration binary ti-connectivity/wl18xx-conf.bin: -2

3. Copy wl18xx-conf-default.bin from /usr/sbin/wlconf to the /lib/firmware/ti-connectivity and rename it as wl18xx-conf.bin

4. I have WL1837 module, so I downloaded WL1837MOD_INI_FCC_CE file from  .INI/wlconf Overview - Texas Instruments Wiki.

     I copied the contents of this file in /usr/sbin/wlconf/official-inis/WL1835MOD_INI.ini (additionally I had to remove blank lines), but You just can copy WL1837MOD_INI_FCC_CE anywhere at      the target.

5. Now You have to go /usr/sbin/wlconf and do this:

     /usr/sbin/wlconf# ./wlconf -o /lib/firmware/ti-connectivity/wl18xx-conf.bin -I /path/to/ini/WL1835MOD_INI.ini

Hi all,

Platform : IMX6SL

Bluedroid on Android kitkat 4.4.3

I have another 2 issues one while data transfer, the other while enabling via GUI.

   1) After enabling bluetooth, while transferring file from third party mobile to IMX_6SL board, file is getting transferred(TX), but vice versa (RX) is not happening, it is giving the error message :

   File not Received

   File : sample.jpg

   Reason : Storage issue

  2) And presently I am inserting my driver via GUI, I am getting an error message while enabling bluetooth via GUI   ie Operation not permitted while loading .ko (driver)Please suggest me what to do?? whether I need to install my driver at boot by adding in init.rc?? if I do it always on boot bt will be in ON State only??  OR Do i need to build my driver along with android source code???

Please suggest me how to proceed further???

Thanks and Regards,

Mutyala Rao.

Please move you question to a new discussion.

[erezsteinberg]

Hi Ivan,

The error you get are because the patches cannot be applied again (they were already applied before). Ignore it -- doesn't make a difference.

I suggest you double-check the SDIO interface IOMUX and declaration in the device tree. Also, check the WIFI Enable GPIO and IRQ.

Use an oscilloscope to see whether the WLAN_ENABLE signal toggles.

Have you tried Bluetooth?

  hciconfig hci0 up

  hcitool scan
