...

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), the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle).
