The throughput will be displayed on the client PC every 5 seconds, as shown in Figure 3-8 . The test will run for 100
seconds and then display the average Ethernet bandwidth.
3.3 EZ-USB GX3 Parameter Configuration in Windows
The EZ-USB GX3 on the CY4701 RDK can be configured for parameters such as USB VID, PID, MAC address, strings,
and others into the external EEPROM by using the Cypress GX3 EEPROM Programming Tool. The GX3 comes with
preconfigured parameters in its internal memory. However, you have the option to choose your own parameters and store
them in the external EEPROM.
To configure the parameters, you need to bind the GX3 test driver to the CY4701 RDK before using the GX3 EEPROM
Programming Tool. The following sections provide detailed descriptions to bind the test driver manually and configure the
parameters by using the Programming Tool.
3.3.1 Connecting CY4701 RDK to Cypress GX3 EEPROM Programming Tool
Follow these steps to connect the device using the Cypress GX3 EEPROM Programming Tool:
1. Open Device Manager and right-click on Cypress GX3 SuperSpeed to Gigabit Ethernet Bridge Controller.
