Overview
|
|
========
|
|
This example can do network iperf test through a USB Ethernet adapter.
|
|
|
|
|
|
Toolchain supported
|
|
===================
|
|
- IAR embedded Workbench 9.20.2
|
|
- Keil MDK 5.36
|
|
- GCC ARM Embedded 10.3.1
|
|

|
Hardware requirements
|
|
=====================
|
|
- Two Micro USB cables
|
|
- One USB A Female to Micro B Male cable
|
|
- HP USB to Gigabit RJ45 Adapter
|
|
- Target Board
|
|
- Personal Computer(PC)
|
|
|
|
Board settings
|
|
==============
|
|
This example only work with the USB high speed port (P9). Set jumpers to enable high speed mode.
|
|
Install jumper in position 1-2 pins of J6 and open J7 jumper.
|
|
|
|
Prepare the Demo
|
|
================
|
|
1. Connect the USB A Female to Micro B Male cable between the USB RJ45 adapter and
|
|
the on-board USB high speed port (P9).
|
|
2. Connect a Ethernet cable with the USB RJ45 adapter.
|
|
3. Connect a USB Micro cable between the host PC and the Debug Link USB port (P6) on the target board.
|
|
4. Connect a USB Micro cable between the PC and the on-board USB power port (P5).
|
|
5. Open a serial terminal on the PC with the following settings:
|
|
- 115200 baud rate
|
|
- 8 data bits
|
|
- No parity
|
|
- One stop bit
|
|
- No flow control
|
|
6. Compile the demo.
|
|
7. Download the program to the target board.
|
|
8. Press the on-board RESET button to start the demo.
|
|
|
|
Running the demo
|
|
================
|
|
1. When the demo is running, the serial port will output:
|
|
|
|
Start the USBX Ethernet Over USB example...
|
|
USB device: vid=0xbda, pid=0x8153
|
|
DHCP In Progress...
|
|
IP address: 10.193.20.10
|
|
Mask: 255.255.255.0
|
|
Gateway: 10.193.20.254
|
|
|
|
2. The board gets a new IP address, for example, 192.168.2.10. On a Linux PC, open a Web browser to
|
|
access the new IP address at http://192.168.2.10, and a iperf test Web page will display.
|
|
|
|
3. To start a UDP iperf test, run the iperf command in a command console on the Linux PC. For example,
|
|
|
|
$ iperf -u -s -i 1
|
|
|
|
4. In the iperf test Web page, click the "Start UDP Transmit Test" button. The test
|
|
will begin.
|
|
|
|
5. When the test is finished, click the "here" in the right side of the Web page.
|
|
It shows the test result like:
|
|
|
|
UDP Transmit Test Done:
|
|
|
|
Destination IP Address: 192.168.2.18
|
|
