Overview
This is a small Iperf demo of the high-performance NetX Duo TCP/IP stack.
SDK version
- Version: 2.15.000
Toolchain supported
- IAR embedded Workbench 9.40.1
- Keil MDK 5.38.1
- GCC ARM Embedded 12.2
- MCUXpresso 11.8.0
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
- Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
- Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Insert Cable to Ethernet RJ45 port and connect it to a ethernet switch.
- Write the program to the flash of the target board.
- Press the reset button on your board to start the demo.
Running the demo
- When the demo is running, the serial port will output:
Start the iperf example... MAC address: 00:11:22:33:44:56 DHCP In Progress... IP address: 192.168.2.10 Mask: 255.255.255.0
-
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.
-
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
-
In the iperf test Web page, click the "Start UDP Transmit Test" button. The test will begin.
-
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 Test Time(milliseconds): 10000 Number of Packets Transmitted: 30328 Number of Bytes Transmitted: 44582160 Throughput(Mbps):35
Note that in UDP receive test, Linux host limits the default bandwidth of UDP packet, use "-b" to specify the bandwidth, for example:
$ iperf -i 1 -u -b 100m -c 10.193.20.10
