Warningnote

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 program the RAM you should click "Download" button in "EZ-USB Interface" window and select the desired file to download.
Unfortunately, you couldn't actually use .iic files but only .hex or .bix files.

 

Warningnote

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

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

 

EEPROM programming
