System Setup

Hardware Requirements

• AW-CU300V2-EVB
• Windows system (OS later than Windows XP) for Labtool.
• Vector Signal Analyzer/WLAN analyzer for transmit measurements.
• WLAN signal generator for receiver measurements.
• RF isolation chamber for receive measurements.
• RF attenuators
• RF cable
  

Environment set up

Download and Install FTDI VCP Drivers (FT2232D)

Install the driver manually. You can get the driver from FTDI’s web site.
https://www.ftdichip.com/Drivers/VCP.htm

Verifying Driver Installation:
To verify that driver installation has completed successfully, you can open the “Device Manager” (right-click My Computer, select Properties). In the System Properties windows, select Hardware, Device Manager. Two “USB Serial Port” should be listed under MY-PCPorts (COM & LPT)

Normal Link Test

Open OS terminal and set USB comport (reference to the page9), set baud-rate as 115200 Enter cmd “help” on the screen to see a full list of commands available for use

Re-write Flash for Other Purpose

For other MCU test purpose, user has to re-write the flash to update the MCU function. To re-write flash, programming through MCU JTAG interface is the suggested method.

Download Libusb-win32

To identify the COM port of FT232 for JTAG interface, libusb is needed.

You can get the driver from libusb-win32’s web site.
https://sourceforge.net/projects/libusb-win32

Install Libusb-win32

Verifying Driver Installation:
To verify that driver installation has completed successfully, you can open the “Device Manager” (right-click My Computer, select Properties). In the System Properties windows, select Hardware, Device Manager. One “USB Serial Converter A” should be listed under MY-PCPorts (lib usb-win32 devices)

Download and Install Cygwin

Install Cygwin:

1. Download Cygwin from: https://www.cygwin.com/setup-x86.exe (for x86 32-bit systems) or https://www.cygwin.com/setup-x86_64.exe (for x86 64-bit systems)
2. Select the option Install from Internet
3. Use default installation path: c:cygwin. If you chose an alternate installation directory, please make sure that there are no spaces in the path.
4. Pick the Local Package Directory (this is the download cache directory)
5. Select the option Direct Connection
6. Select any mirror you want to use
7. Add additional packages to the default selection:

Click “Next”. The Cygwin Setup window will show the progress as each package gets installed.
Note: If you are not familiar with cygwin, please visit https://cygwin.com/ for additional information and details. In particular, the Cygwin User Guide (https://cygwin.com/cygwin-ug-net/) is a good resource for new users.

Insert file “OpenOCD.zip” for FW burn in.

Unzip “CU300_OpenOCD.zip” and put “readelf.exe” to C:cygwinbin

Unzip “CU300_OpenOCD.zip” and put them to C:cygwin

Execute Cygwin,bat

Move to working folder

Burn in FW for RF testing

Example

Link test with RF normal FW(default):

Check config_normal_RTC.txt, layout.txt … 6 files in the Open OCD folder

Key in cmd to burn in normal FW.

Now you can perform normal link testing. (Needs to re-boot the EVB after burning in)

RF test with MFG FW:

For RF testing with MFG FW, you needs to re-burn in the FW as below. Check config_mfg.txt, layout.txt … 5files in Open OCD folder

Key in cmd to burn in MFG FW.

Check if all files are burn in correctly

Now you can perform MFG RF testing. (Needs to re-boot the EVB after burning in)

RF Test (w/MFG FW)

Run Lab tool in Windows OS.

Generate 802.11b/g/n Packet commands

a. Tx on CH 6 at 10 dBm with a CCK-11Mbps data rate in 20 MHz BW mode on WiFi

25 // Stop Tx112 0 // Set to 20 MHz BW 12 6 // Set to CH 6 22 6 10 0 // Set to CH 6 at 10 dBm Output Power with CCK/BPSK Data Rate on WiFi
b. Tx on CH 100 at 8 dBm with a MCS7 Data rate in 20 MHz BW Mode on WiFi

25 // Stop Tx 112 0 // Set to 20 MHz BW 12 13 // Set to CH 13 22 13 8 1 // Set to CH 13 at 8 dBm Output Power with OFDM Data Rate on WiFi 25 1 22 // Tx at MCS 7

Data rate set up

B mode & G mode:

1Mbps	5.5Mbps	11Mbps	6Mbps	9Mbps	12Mbps	18Mbps	24Mbps
1	3	4	6	7	8	9	10
36Mbps	48Mbps	54Mbps
11	12	13

N mode:

MCS0	MCS1	MCS2	MCS3	MCS4	MCS5	MCS6	MCS7
15	16	17	18	19	20	21	22

After you type above command, you can measure the 802.11b/g/n packet by your RF test instrument (exp:  Agilent 4010, IQview…).

Generate 802.11 b/g/n continuous symbol Commands

a. Cont. Tx on CH 7 at 8 dBm with a MCS7 Data rate in 20 MHz BW Mode on WiFi

17 // Stop Cont. Tx 25 // Stop Tx 112 0 // Set to 20 MHz BW 12 7 // Set to CH 36 22 7 8 1 // Set to CH 36 at 8 dBm Output Power with MCS Data Rate on WiFi 25 1 22 // Tx at MCS 7 25 // Stop Tx 17 1 22 // Cont. Tx at MCS7 17 // Stop Cont. Tx

Others Commands

1. Command 45-Check the MAC
2. Command 99-Quit the test mode/ Quit the MFG tool
