USB FX2 microcontroller Configuration (RAM Firmware)

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

...

Warning
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.

IIC EEPROM Configuration (EEPROM Firmware)

Tip

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

...

Warning

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 (RAM for CyConsole and xxx for CyControl), but the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle).
