Open CyControl

The firmware actually changes (it runs on USB FX2 microcontroller's RAM) only when

you reset the TE USB FX2 module;
you power off and power on the TE USB FX2 module;
you write the USB FX2 microcontroller's RAM (but the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle).

To start CyControl (Cypress USB Control Center) you should double click the file CyControl.exe.

After this one of this two windows appears.

Programming failed

Programming succeeded

The RAM can be programmed even if EEPROM switch is disabled.

If you don't also write the IIC EEPROM ("Program>FX2 64KB EEPROM"), the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle.

EEPROM programming

To program the Large (64K) EEPROM you should click "Program FX2" and select "64KB EEPROM". Then you should select the .iic file to download.

Programming failed:
it happens when EEPROM
switch is disabled.

Programming succeeded:
it happens when EEPROM
switch is enabled.

If the TE USB FX2 module exit from reset or is powered on, the IIC EEPROM content programs/configures the USB FX2 microcontroller RAM
