An update boot  (aka TE USB FX2 firmware update) is a multi-step boot operation:

• follow the same procedure of TE USB FX2 driver installation (Generation 3);

• Check that EEPROM connection is enabled (EEPROM switch is set in a way to enable EPPROM connection to USB FX2 microcontroler);
  

  EEPROM connection shall always be enabled during EEPROM programming.

• Cypress firmware update tools and OpenFutNet can read and write the EEPROM:

  1. 1. for example using CyControl (Cypress USB Control Center);

     2. for example using CyConsole (Cypress USB Console);
     3. for example using OpenFutNet update boot.
