Erasing or Updating Firmware on an EEPROM When the Control Panel Isn't Available

Question: How is it possible to update the firmware in the EEPROM interfaced to an FX2LP once the device is bound to a custom driver?



This can be done in two ways:

1.Remove the EEPROM enable jumper on the board.  Plug in the USB cable, and the board will be recognized as "...EEPROM missing" in the EZ-USB development tools. Replace the EEPROM Enable jumper to the enable position and reprogram the EEPROM.

2.Modify CyUSB.inf to include the new VID/PID of the device and update the device driver from device manager.. Now you can reprogram the EEPROM from the EZ-USB development tools.
