3 WFA certification test procedure

This section shows the sequence of operations to run in order to test the Wi-Fi features.

3.1 Set up the serial console

Set up the test. See Section 2. Follow these steps to setup the serial console and access the i.MX 8M Quad device terminal: · Open the serial console and login into the device

ubuntu@ubuntu-desktop:/# sudo minicom -s -D /dev/ttyUSBx

· ttyUSB0 or ttyUSB01 are the serial devices. The minicom setup configuration is given below:

A – Serial Device

: /dev/ttyUSBx

E – Bps/Par/Bits

: 115200 8N1

F – Hardware Flow Control : No

G – Software Flow Control : No

Note: The baud rate is set to 115200 in the given minicom setup configuration. · Save and exit.

3.2 Copy the required files
· Connect the device to the control network · Give the control network IP to the wired interface · Use SCP to copy NXP_WTS_AGENT_IMX_bin repository to i.MX 8M Quad EVK board. The command on Linux host is as follows:
# scp -r <absolute_path>/NXP_WTS_AGENT_IMX_bin root@192.168.X.X:/home/root/
Where 192.168.X.X is the board IP which you set in the previous step. · Set the permission to the files within NXP_WTS_AGENT_IMX_bin repository copied to i.MX 8M Quad EVK
board using the command:
chmod 777 * -Rf
· Copy the driver file set [bin_wlan/*] to NXP_WTS_AGENT_IMX_bin repository · Copy the firmware file set [FW_Image/*] to /lib/firmware/nxp/ repository of i.MX 8M Quad EVK board

3.3 Cross compilation of WTS DUT agent
This section shows how to cross compile the certification agent for Linux Yocto. · For how to set up the toolchain, refer to the section i.MX 8M evaluation platform with Yocto in ref.[3]. · Extract the content of the zip file.
ubuntu@ubuntu-desktop:/# unzip NXP_WTS_QTT_AGENT_R2_1.zip
· Source the toolchain. ubuntu@ubuntu-desktop:/# source /opt/fsl-imx-wayland/5.10-hardknott/environment-setupcortexa53-crypto-poky-linux
· Go to WTS-R-2.1 directory. ubuntu@ubuntu-desktop:/# cd WTS-R-2.1/
· Extract the content of the zip file. ubuntu@ubuntu-desktop:/# unzip NXP_WTS_AGENT_SRC_R2.1.zip
· Open Makefile.inc file and disable static compile. ubuntu@ubuntu-desktop:/# gedit Makefile.inc #CC = gcc
· Compile the source code. ubuntu@ubuntu-desktop:/# make
At the end of the compilation, the directory NXP_WTS_AGENT_IMX_bin is created at the current path. The files in NXP_WTS_AGENT_IMX_bin directory are used on the target android platform.

3.4 Load the driver
Use the cd command to go to NXP_WTS_AGENT_IMX_bin repository where the driver files are located on i.MX board. Note: By default the turbo mode is enabled in the firmware. But turbo mode must be disabled for all the certification programs because turbo mode requires to update wmm parameters as per the specification. See Section 3.4.1. Run the shell script load.sh script to install the driver located in NXP_WTS_AGENT_IMX_bin repository.
./load.sh
Note: The shell script changes with the device and respective features being tested. Refer to the program specific data for the script to use. Check the version of the build with the following command:
./mlanutl mlan0 version

3.4.1 Disable Turbo mode · Edit turbo_mode.conf configuration file to change the value for turbo mode enablement.

#File : turbo_mode.conf

## WMM turbo mode config command

turbo_mode_set={

CmdCode=0x0016 # do NOT change this line

Action:2=1

# 1 – SET

OID:2=0x27

# OID_WMM_TURBO_MODE

Size:2=128

Value:128=5

# 1 — Enable turbo_mode_1; 2 — Enable turbo_mode_2; otherwise,

disable turbo_mode

}

· Use mlanutl utility to update the settings for turbo mode Command syntax:

./mlanutl <wireless interface> hostcmd <conf file name> <config structure name>

Command example:

root@imx8mnevk:~# ./mlanutl mlan0 hostcmd config/turbo_mode.conf turbo_mode_set

Command output example:

HOSTCMD_RESP: CmdCode=0x16, Size=0x8e, SeqNum=0x26, Result=0000 payload: len=134 01 00 27 00 80 00 05 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
