You can use CyConsole ("Options" > "EZ-USB Interface" > "Download" and a .hex or .bix file) or CyControl ("Program FX2 > RAM" and a .hex or .iic file) to directly program the firmware file (.hex, .bix or .iic file) into the USB FX2 microcontroller's RAM.

If you don't also write the IIC EEPROM ("Options" > "EZ-USB Interface" > "Lg EEPROM" for CyConsole and "Program>FX2 64KB EEPROM" for CyControl), the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle. |

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

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

If you don't also write the SPI Flash memory, the new bitstream image is lost if the TE USB FX2 module goes under reset or power off/on cycle. |

If the TE USB FX2 module exit from reset state or is powered on (in the default state of switches), the SPI Flash content programs/configures the FPGA. |
