The firmware used (running on the FX2 microcontroller) is normally (EEPROM switch enabled) retrieved from EEPROM when a reset occurs. It is also possible to directly write the RAM of FX2 microcontroller to change the current running firmware.

For a A general introduction to USB bulk transaction and FX2 microcontroller firmware , see section "General USB and FX2 firmware introduction"is available here. TE USB FX2 modules are shipped with a preloaded FX2 USB microcontroller reference firmware inside the EEPROM.For an introduction to the reference firmware, see section "Reference firmware (Trenz Electronic v3.02 description): preloaded USB Firmware (FX2 USB microcontroller, EEPROM)". The preloaded firmware exposes Trenz Electronic Firmware API (TE API Commands (FW APIs)) to the host computer software (through USB). To change the EEPROM content (reference firmware) from Generation 2 to Generation 3, you shall follow this procedure. You may also watch this video play list. For an introduction to recovery boot and regular/update boot, see sections "USB FX2 microcontroller's firmware configuration", "USB connection is unresponsive", "Recovery Boot (TE USB FX2 Firmware Recovery)" and "Update Boot (TE USB FX2 Firmware Update)"., recovery boot and update boot.

(1) The TE USB FX2 module (in recovery boot) is served by the
Cypress USB Generic Driver; this driver allows Cypress firmware update tools (Cypress Console, Cypress Control Center) and OpenFutNet to work with the Cypress EZ-USB FX2 microcontroller on the module.
