|
This is a small Iperf demo of the high-performance NetX Duo TCP/IP stack.
|
|
|
|
|
|

|
- IAR embedded Workbench 9.30.1
|
|
- Keil MDK 5.37
|
|
- GCC ARM Embedded 10.3.1
|
|
- MCUXpresso 11.6.0
|
|
|
|
Hardware requirements
|
|
=====================
|
|
- Mini/micro USB cable
|
|
- Network cable RJ45 standard
|
|
- EVK-MIMXRT1020 board
|
|
- Personal Computer
|
|
|
|
Board settings
|
|
==============
|
|
No special settings are required.
|
|
|
|
Prepare the Demo
|
|
================
|
|
1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
|
|
2. Open a serial terminal with the following settings:
|
|
- 115200 baud rate
|
|
- 8 data bits
|
|
- No parity
|
|
- One stop bit
|
|
- No flow control
|
|
3. Insert Cable to Ethernet RJ45 port and connect it to a ethernet switch.
|
|
4. Write the program to the flash of the target board.
|
|
5. Press the reset button on your board to start the demo.
|
|
|
|
Running the demo
|
|
================
|
|
1. When the demo is running, the serial port will output:
|
|
|
|
Start the iperf example...
|
|
DHCP In Progress...
|
|
IP address: 192.168.2.10
|
|
Mask: 255.255.255.0
|
|
|
|
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
|
|
