Table 3 lists the official NXP branded i.MX6 Reference Platforms and which Murata Adapter Version

should be used.

 NOTE: Murata strongly recommends the recommended Adapter configuration.

As Table 3 indicates, currently three (3) NXP i.MX6 Platforms are supported. There is only one

complication for default (SDIO interrupt in-band signaling) configuration. Namely the i.MX

6Quad/DualLite SABRE-SD requires rework to successfully interface with the Murata hardware. As

shipped from the factory, the i.MX 6Quad/DualLite SABRE-SD does not connect the J13 Bluetooth

ribbon cable connector to the necessary UART and control signals. Please reference the Murata

Hardware User Manual for necessary rework.

The only other optional hardware configuration is for i.MX 6SoloX SABRE-SD. The V1 adapter

requires no rework for this platform and is the default configuration. However if the V2 adapter is

desired (frees up one SD2 card slot) then rework is necessary. For specifics please reference the

Murata Hardware User Manual.

Note that the NXP Android 5.1.1 Lollipop release only supports SDIO in-band interrupts. Out-of-band

interrupts are supported by hardware but require software modifications.

2 Connecting to i.MX 6SoloX SABRE-SD (V1 Adapter)

Referring to Table 3, the V1 Adapter is the recommended adapter for this platform. No rework is

required, Murata Wi-Fi/BT EVB is oriented right-side up, and it provides both Wi-Fi and BT

functionality via SD3/SD2 slots: see Figure 2 below.

[1] Make sure no power is applied to i.MX 6SoloX SABRE-SD.

[2] Check that VIO setting on Murata i.MX6 Interconnect V1 Adapter (Part #2 in Table 1) is set to

3.3V (VBAT_SDIO). Refer to Red Rectangle for correct jumper setting in Figure 5.

[3] Insert V1 Adapter board into SD3 slot and SD Card Extender into SD2 slot. Note the

orientation as shown in Figure 2.

[4] Connect antenna (Part #4) to the SMA connector of the Murata EVB (Part #1).

[5] Now you can connect the EVB to the 60-pin Samtec connector on the V1 Adapter board.

[6] Make sure an appropriate LVDS LCD (touch screen display) is connected to SoloX as the blue

arrow in Figure 2 indicates. This is the default configuration for the SoloX binary image.

[7] Prepare SD card to boot platform per Section 5.

[8] Power on platform. If the EVB being used is not ZP (default) or additional utilities such as “wl”

tool need to be added, then refer to Section 6 on necessary file modifications (i.e. has to be

done for 1BW, 1DX, 1FX, and SN8000).

[9] Refer to Section 7 to test/verify Wi-Fi and Bluetooth functionality.

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 11 of 23 www.murata.com

3 Connecting to i.MX 6SoloLite EVK (V1 Adapter)

Referring to Table 3, V1 Adapter is the only solution that will work for this platform. Murata Wi-Fi/BT

EVB is oriented right-side up, and it provides both Wi-Fi and BT functionality via SD1 slot with control

signals connected from SD3 slot using SD Card Extender: see Figure 3 below.

[1] Make sure no power is applied to i.MX 6SoloLite EVK.

[2] Check that VIO setting on Murata i.MX6 Interconnect V1 Adapter (Part #2 in Table 1) is set to

3.3V (VBAT_SDIO). Refer to Red Rectangle for correct jumper setting in Figure 5.

[3] Insert V1 Adapter board into SD1 slot and SD Card Extender into SD3 slot. Note the

orientation as shown in Figure 3.

[4] Connect antenna (Part #4) to the SMA connector of the Murata EVB (Part #1).

[5] Now you can connect the EVB to the 60-pin Samtec connector on the V1 Adapter board.

[6] Default Android image requires MCIMX28LCD as a display and USB mouse connected.

[7] Prepare SD card to boot platform per Section 5.

[8] Power on platform. If the EVB being used is not ZP (default) or additional utilities such as “wl”

tool need to be added, then refer to Section 6 on necessary file modifications (i.e. has to be

done for 1BW, 1DX, 1FX, and SN8000).

[9] Refer to Section 7 to test/verify Wi-Fi functionality. Bluetooth is not enabled in software.

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 12 of 23 www.murata.com

4 Connecting to i.MX 6Quad/DualLite SABRE-SD (V2 Adapter)

Referring to Table 3, the i.MX 6Quad/DualLite SABRE-SD presents additional challenges. As

shipped from the factory, the i.MX 6Quad/DualLite SABRE-SD does not connect the J13 Bluetooth

ribbon cable connector to the necessary UART and control signals. Please reference the Murata

Hardware User Manual for necessary rework. NXP also details the board rework in their schematic

file (Bluetooth page). Page 15 of the NXP schematic (SPF-27516_C3.pdf) correctly captures the

necessary rework to be done.

Repeated here:

NOTE: To use J13, populate resistors R209 - R213 and depopulated the SPI NOR FLASH

U14. Resistors R214 and R215 should not be populated because both UART outputs (TXDs)

have been crossed together and both UART inputs (RXDs) have been crossed together. To

make the UART work correctly, solder a jumper wire from R215 pad 1 to R214 pad 2 and from

R215 pad 2 to R214 pad 1.

 The following steps will only pass if NXP Platform has been correctly reworked.

NOTE: The NXP i.MX6 platform has been inverted. This makes working with Wi-Fi/BT EVK

much easier. The one drawback is if Ethernet port must be accessed. To properly match Wi-

Fi/BT EVK and i.MX6 platform heights, nylon washers are added as additional spacers to

“standard” NXP i.MX6 standoffs.

[1] Make sure no power is applied to i.MX 6Quad/DualLite SABRE-SD.

[2] Check that VIO setting on Murata i.MX6 Interconnect V2 Adapter (Part #3 in Table 1) is set to

3.3V (VBAT_SDIO). Refer to Red Rectangle for correct jumper setting in Figure 8.

[3] After connecting ribbon cable to both adapter and i.MX6Q/DL, insert Adapter board into SD2

slot. Note the orientation as shown in Figure 4.

[4] Connect antenna (Part #4) to the SMA connector of the Murata EVB (Part #1).

[5] Now you can connect the EVB to the 60-pin Samtec connector on the Adapter board.

[6] Make sure an appropriate LVDS LCD (touch screen display) is connected to SoloX as the blue

arrow in Figure 4 indicates. This is the default configuration for the Quad/DualLite SABRE-SD

binary image.

[7] Prepare SD card to boot platform per Section 5.

[8] Power on platform. If the EVB being used is not ZP (default) or additional utilities such as “wl”

tool need to be added, then refer to Section 6 on necessary file modifications (i.e. has to be

done for 1BW, 1DX, 1FX, and SN8000).

[9] Refer to Section 7 to test/verify Wi-Fi and Bluetooth functionality.

5 Preparing Bootable SD Card for i.MX6 with Murata Wi-Fi/BT EVK

The current release supported is NXP Android 5.1.1 Lollipop GA BSP. This is the first GA release

from NXP which provides verified/tested Wi-Fi/Bluetooth functionality on all major i.MX6 platforms (as

detailed in this guide – i.MX 6UltraLite not supported on Android O/S). NXP provides pre-built images

for each platform that include all necessary components to get (default) Murata Type ZP EVK up and

running.

Although the Android “Demo Images” are made available here, the tool for partitioning the SD card is

only released as part of the source code (involves pulling code from “git” repository). As such

flashing the NXP Android image to SD card is somewhat complicated without a pre-partitioned SD

card (formatted for Android NXP image). For more information on SD card formatting, you can refer to

Section 5.1.1 “Storage Partitions” in the NXP Android User’s Guide.

The recommended approach to flashing the NXP “Demo Images” is to use NXP’s Manufacturing

Tool (Windows based) which allows the user to partition/flash the SD card in one step (once

Manufacturing Tool is downloaded/installed and necessary “Demo Image” files are downloaded and

copied over). These steps are detailed in the NXP Android Quick Start Guide.

To enable the remaining Murata Wi-Fi/BT EVK’s (1BW, 1DX, 1FX, and SN8000), it is necessary to

modify the Wi-Fi NVRAM (calibration file – bcmdhd.cal), Wi-Fi firmware binaries (fw_bcmdhd.bin,

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 14 of 23 www.murata.com

fw_bcmdhd_apsta.bin), and Bluetooth patchfile (Type_ZP.hcd is default). All these files reside in

“/etc/firmware/bcm” folder. The “Demo Images” are built as Android “user images” so specific steps

are required to modify the root file system. These steps are documented in Section 6.

Lastly the user may desire to add tools for specific RF testing and/or performance tests. “WL” tool and

“iperf” are integrated into the Android image. For Cypress documentation on “WL” tool please refer to

this link.

5.1 Getting Signed Up for Support Portals

You should already have access to “My.Murata” support portal. If not please download “My.Murata”

support site access guide from here.

For additional support resources, it is recommended to register at both NXP and Cypress Community

websites. Once you are registered please email imxfaq@murata.com to gain access to both

Murata/i.MX Portal (NXP site) and NXP/Murata i.MX Support Portal (Cypress site).

Turnaround for support portal access is typically no more than 24 hours.

5.2 Downloading i.MX6 Demo Image Files to Flash SD Card (or EMMC)

Table 5 provides direct download links to i.MX6 “Binary Demo File” for each NXP Platform. The

available SD card images are included in these downloads. All download links below originate on this

NXP webpage. Simply click on the hyperlink for the desired “Demo Image File” and download the

package. After downloading, extract the appropriate “full image” version from the bundle/package

(note filename underneath “demo image” hyperlink).

The final extracted package (containing u-boot, kernel, recovery, and system image) will be copied

over to NXP/Freescale MFGTool folder to flash the platform. Note that there may be multiple versions

of the aforementioned components. Please reference the NXP Android Quick Start Guide for more

details.

5.3 Flashing SD Card (or EMMC)

We recommend NXP/Freescale MFGTool to flash the Android image to SD Card or EMMC. It allows

the end user to both partition and flash image files in one step. The procedure for using MFGTool is

documented in the NXP Android Quick Start Guide. There is a different section covering the steps

used to flash each of the NXP i.MX6 platforms (refer to Sections 3, 5, and 6 for supported platforms).

The very first step is to download and install the MFGTool software to your Windows PC. Download

the Android version of MFGTool located here. Once downloaded, extract the MFGTool package to

the desired folder on your Windows PC. Now refer to Sections 3, 5 or 6 in NXP Android Quick Start

Guide to flash the Android image on i.MX 6Quad/DualLite SABRE-SD, i.MX 6SoloLite, and i.MX

6SoloX respectively.

5.3.1 MFGTool Notes

1) If after double-clicking the appropriate *.vbs file, the “MfgTool_MultiPanel” GUI does not

come up correctly (i.e. no “HID-compliant device” found) make sure you have the correct

USB driver installed. The “imxusb.inf” file is located at “<MFGTool-

Dir>\Drivers\iMX_BulkIO_Driver”.

2) If prompted by Windows’ O/S to “format drive”, click the “cancel” option.

3) After flashing platform, make sure to power down and reset boot switches.

5.3.2 Enabling Shell Console on i.MX Platform

To enable shell console and ability to modify file system, make sure to append

"androidboot.selinux=disabled" and "androidboot.dm_verity=disabled" to U-Boot’s bootargs. Sections

3.4, 5.4, and 6.4 in NXP Android Quick Start Guide provide exact bootargs’ strings. The ability to

modify file system is essential when using non-ZP EVB (i.e. 1BW, 1DX, 1FX, SN8000). It is also

important for adding utilities such as “WL” tool which is used for RF testing.

6 File Modifications Necessary When Not Using Type ZP EVB

The default Android image from NXP only supports the Type ZP EVB. To support the other Murata

EVB’s (1BW, 1DX, 1FX and SN8000) with the same Android image, we need to copy over the

necessary files to the Android file system (replacing original ones). As shown in “Original File” column

of Table 6, these files are located in the “/etc/firmware/bcm” folder.

6.1 Sourcing Replacement WLAN and Bluetooth Binary and Configuration Files

The easiest source to pull necessary files from is the NXP Linux 3.14.52 file system tarball. The file

system for any of the major i.MX6 Platforms will work: i.MX 6Quad, i.MX 6SoloX, i.MX 6SoloLite, and

i.MX 6UltraLite. Table 6 quotes the i.MX 6UltraLite file system source: easiest to download given its

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 16 of 23 www.murata.com

smaller file size. The “fsl-iamge-gui-x11-im6ul.tar.bz2” file can be extracted from the i.MX 6 UltraLite

Linux Binary Demo Files package.

After the i.MX 6Ultralite Linux 3.14.52 file system is downloaded, please extract the specified files in

the “Replacement File” column in Table 6 for the given Murata EVB: 1BW, 1DX, 1FX, and SN8000.

6.2 Setting up System to Allow File Copy/Replace

1) Connect both USB console and USB OTG connections on i.MX Platform to Linux PC (or

Windows PC with adb utility installed).

2) Ensure the shell console is enabled (refer to Section 5.3.2).

3) Boot the i.MX Platform and enable USB debugging by clicking on “Settings->About Tablet-

>Build Number” seven (7) times. This is standard procedure for Android platform.

4) Now go to “Settings->Developer options” and turn on “USB debugging”.

5) A pop-up window should now prompt you to “Allow USB debugging?” Select “OK” to confirm.

6) On shell console, enter the “mount” command to make file system writable: “mount –o remount

–rw /system”

6.3 Additional Notes on WLAN and Bluetooth File Replacement

 The 1DX and 1FX files only differ when it comes to Bluetooth patchfile. 1FX is a WLAN-only

module. The WLAN core on 1DX and 1FX are equivalent.

 “Type_ZP.hcd” is the default Bluetooth patchfile name. This is specified in

“/system/etc/bluetooth/bt_vendor.conf” file. The approach of replacing this file is done to

shorten/simplify the steps. Another option on adding BT patchfiles for other modules would be

to modify the “bt_vendor.conf” file to be consistent with the new patchfile name for the non-ZP

module.

 There are two WLAN firmware files used for either Client (fw_bcmdhd.bin) or SoftAP

(fw_bcmdhd_apsta.bin) mode. Some modules use the same file for both modes. As such the

two files only differ in name. Other modules (ZP and SN8000) have different firmware files:

typically used to optimize SoftAP mode (enhance throughput).

 The default WLAN NVRAM file used has SDIO in-band signaling enabled.

6.4 Example Command Sequence to Copy/Replace WLAN and Bluetooth Files

Given the number of different steps, this section is included to provide all the steps (line by line) to

end user. In this example, we are modifying Android file system to support Murata Type 1DX EVB.

 Follow steps 1 through 5 in Section 6.2. Now enter the “mount” command on the shell console

and verify successful response (i.e. “re-mounted”):

root@sabresd_6sx:/ # mount –o remount –rw /system

EXT4-fs (mmcblk3p5): re-mounted. Opts: (null)

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 18 of 23 www.murata.com

Now that the Android file system is re-mounted, we should be able to use “adb push” command from

Host PC to transfer files to Android “/sdcard” partition.

 Download the i.MX 6 UltraLite Linux Binary Demo Files package (assume downloads go to

“~/Downloads”). Note that in following sequence the one Type 1DX WLAN firmware is being

used for both SoftAP and Client. Also, to simplify process we are just renaming the 1DX

Bluetooth patchfile to “Type_ZP.hcd”.

cd ~/Downloads

mkdir ~/temp

mv L3.14.52_1.1.0-ga_images_MX6UL.tar.gz ~/temp/

cd ~/temp

tar –xvzf L3.14.52_1.1.0-ga_images_MX6UL.tar.gz

cd L3.14.52_1.1.0-ga_images_MX6UL

tar –xvjf fsl-image-gui-x11-imx6ul.tar.bz2

cd lib/firmware/bcm/1DX_BCM4343W

adb push bcmdhd.1DX.SDIO.cal /sdcard/bcmdhd.cal

adb push fw_bcmdhd.bin /sdcard/fw_bcmdhd.bin

cd ../../../../etc/firmware/

adb push BCM43430A1.1DX.hcd /sdcard/Type_ZP.hcd

Now all relevant 1FX files are on the Android “/sdcard” partition. We need to invoke copy command

on shell console to move them to the right location on Android file system. However prior to copying

over the original files (for Type ZP EVB), we should back the existing files up.

 On shell console, enter the following commands:

root@sabresd_6sx:/ # mkdir /etc/firmware/bcm/Type_ZP_Backup

root@sabresd_6sx:/ # cp /etc/firmware/bcm/* /etc/firmware/bcm/Type_ZP_Backup/

 Verify files copied over correctly with “ls” command:

root@sabresd_6sx:/ # ls /etc/firmware/bcm/Type_ZP_Backup/

Type_ZP.hcd

bcmdhd.cal

fw_bcmdhd.bin

fw_bcmdhd_apsta.bin

 Now copy over new 1DX files to “/etc/firmware/bcm” folder from Android “/sdcard” partition:

root@sabresd_6sx:/ # cp /sdcard/bcmdhd.cal /etc/firmware/bcm/

root@sabresd_6sx:/ # cp /sdcard/fw_bcmdhd.bin /etc/firmware/bcm/

root@sabresd_6sx:/ # cp /sdcard/fw_bcmdhd.bin /etc/firmware/bcm/fw_bcmdhd_apsta.bin

root@sabresd_6sx:/ # cp /sdard/Type_ZP.hcd /etc/firmware/bcm/

 1DX Wi-Fi and Bluetooth file setup complete!

We now have to power down the i.MX platform, connect Murata 1DX EVK and boot up again.

7 Test/Verification of Wi-Fi and Bluetooth

With Android’s polished interface, this step is definitely easier than Linux. We just use the graphical

user interface to verify both Wi-Fi and Bluetooth functionality. The shell console is quite useful for

verifying correct/expected output when bringing up either the Wi-Fi or Bluetooth interface.

If there are any issues bringing up either Wi-Fi and/or Bluetooth, then it is highly recommended to

attempt bring-up with Linux as it is easier to diagnose failures. Please refer to the Murata Quick Start

Guide (Linux) for more information regarding booting the platform with Linux.

7.1 Bringing up Wi-Fi for Quick Test/Verification

7.1.1 Associating to Access Point or Wireless Router

Standard Android interface applies. Go to “Settings->Wi-Fi” and turn Wi-Fi on. If hardware/software

configured correctly you should see the scan list of visible SSID’s.

To show more functionality you can associate to a given Access Point or Wireless Router. Once the

IP address is obtained, you can check connectivity by using “ping” command on shell console.

Otherwise if AP (associated to) provides an internet connection, you can use the Internet Browser to

pull up a desired webpage.

7.1.2 Testing Wi-fi Direct

The Murata Wi-Fi solution on i.MX supports Wi-Fi Direct. You can test both modes: P2P GO (Group

Owner) and P2P Client. Go to “Settings->Wi-Fi->Advanced->Wi-Fi Direct”. From the “Wi-Fi Direct”

menu, you can now initiate a P2P GO or respond to an “Invitation to Connect” (P2P Client). If a P2P

connection is successful, you will see “Connected” under the “Peer devices” name.

Now that we have two devices associated in P2P network, we can invoke “ping” from shell console to

test connectivity. To query the IP address of i.MX platform’s wireless connection, you can invoke

“ifconfig p2p-wlan0-0” at the shell console. Note: if “p2p-wlan0-0” does not work then look through the

shell console output for “p2p-wlan0-x” where “x” is an integer.

7.1.3 Testing Wi-Fi Hotspot (SoftAP)

The Murata Wi-Fi solution on i.MX supports Wi-Fi hotspot. Go to “Settings->More->Tethering &

portable hotspot”. Click on “Set up Wi-Fi hotspot” to customize SSID, security setting and password

required by client for authentication. Now enable the hotspot by turning on “Portable Wi-Fi hotspot”. If

successful the string “Portable hotspot <SSID Name> active” should appear below “Portable Wi-Fi

hotspot” field.

Second step is to now associate to Wi-Fi hotspot from a client. Once association is successful, you

can run a connectivity test using “ping” command on shell console. To find IP address of Wi-Fi

hotspot, enter “ifconfig wlan0” on shell console.

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 20 of 23 www.murata.com

7.2 Bringing up Bluetooth for Quick Test/Verification

To verify Bluetooth connectivity (not enabled on i.MX 6SoloLite EVK), just go to “Settings->Bluetooth”

and turn on. The visible Bluetooth devices should then come up under “Available devices”. To check

connectivity you can pair/connect with a specific Bluetooth device.

8 Verifying Adapter Boards

To ensure correct functioning of Murata Wi-Fi/BT EVK, it is of key importance to check the adapter

configuration based upon jumper settings and short pads open/closed.

8.1 Murata i.MX InterConnect V1 Adapter

Figure 5: Murata i.MX InterConnect V1 Adapter – Top

Refer to Figure 5 for default configuration on V1 Adapter board. VIO jumper should be in RED

position – set for VBAT_SDIO which is approximately 3.3V (i.e. VIO = VBAT). The adapter allows for

1.8V VIO operation (ORANGE position) but this Quick Start Guide currently does not support that

option. A future revision will support both 1.8V and 3.3V VIO signaling on platforms/configurations

that permit it. Note that there are no closed (soldered) short-pads on V1 Adapter from top view. Of

course you will see the soldered connections for WL_HOST_WAKE, WL_REG_ON, and

BT_REG_ON. Two figures are presented for the bottom side of the Murata i.MX InterConnect V1

Adapter. This is done to give unobstructed views of all the short pads. Refer to Figure 6: Murata

i.MX InterConnect V1 Adapter – Bottom #1 and Figure 7: Murata i.MX InterConnect V1 Adapter

– Bottom #2 for default configuration on V1 Adapter Board. Compare your adapter with the short

pads (open versus closed). There should be a one-to-one mapping. The short pad selections on

bottom of adapter board connect Bluetooth UART through to SD_DAT4..7 pins (TP109, TP122,

TP116, and TP130 closed/soldered). TP133 short pad is closed/soldered to connect VBAT_SDIO

(voltage supply from SD VDD Pin #4) to VBAT_IN which powers the Murata Wi-Fi/BT EVB. The other

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 21 of 23 www.murata.com

power supply option is to use an external power supply: short TP134 (with TP133 open) and connect

external supply to TP131 and TP132 (marked “EXT VBAT 4-5V” and “GND” on silkscreen – see

Figure 5. The V1 Adapter is pre-wired to SD Card Extender. This is done to provide “plug ‘n play”

interoperability with NXP i.MX 6SoloX SABRE-SD and i.MX 6SoloLite EVK. The connected signals

are BT_REG_ON (yellow), WL_REG_ON (orange), and WL_HOST_WAKE (blue). This allows direct

mapping to i.MX6 GPIO’s to these control signals. For additional specific information on default

configuration, please reference the Murata Hardware User Manual.

8.2 Murata i.MX InterConnect V2 Adapter

To ensure correct functioning of Murata Wi-Fi/BT EVK, it is of key importance to check the adapter

configuration based upon jumper settings and short pads open/closed. V2 Adapter is much simpler

than V1. However it is still important to check all connections to make sure they match defaults.

Refer to Figure 8: Murata i.MX InterConnect Adapter V2 Adapter – Top. VIO jumper should be in

RED position – set for VBAT_SDIO which is approximately 3.3V (i.e. VIO = VBAT). The adapter

allows for 1.8V VIO operation (ORANGE position) but this Quick Start Guide currently does not

support that option. A future revision will support both 1.8V and 3.3V VIO signaling on

platforms/configurations that permit it. Only two short pads are close on top: TP14 and TP13. TP14

short pad is closed/soldered to connect VBAT_SDIO (voltage supply from SD VDD Pin #4) to

VBAT_IN which powers the Murata Wi-Fi/BT EVB. The other power supply option is to use an

external power supply: short TP15 (with TP14 open) and connect external supply to TP11 and TP12

(marked “Ext/VBAT4-5V” and “GND” on silkscreen - see Figure 8). TP13 connects the BT_REG_ON

control signal.

Figure 8: Murata i.MX InterConnect Adapter V2 Adapter – Top

Figure 9: Murata i.MX InterConnect Adapter V2 Adapter - Bottom

Murata Wi-Fi/BT EVK for i.MX6 Quick Start Guide (Android) 1.1 11/13/17 Page 23 of 23 www.murata.com

Refer to Figure 9: Murata i.MX InterConnect Adapter V2 Adapter - Bottom. Both TP20 and TP21

short pads are closed to connect WL_REG_ON and WL_HOST_WAKE respectively.

WL_HOST_WAKE is an optional out-of-band interrupt signal that is not defined in this Quick Start

document. It will be documented (and optionally enabled) in future version. For additional specific

information on default configuration, please reference the Murata Hardware User Manual.
