How to restore FT2232 EEPROM back to factory settings?

Question

When I used the FT_PROG tools to config the VCP port for debugging my application, I accidentally erased the EEPROM attached to FT2232H. After that, Minized board could not be recognized by Vivado hardware server.

How to restore it? Could you please help me in some ways?

Unfortunately, as stated in https://www.xilinx.com/support/answers/68889.html, "the proprietary solution is not documented or supported, and cannot be provided to customers as a reference."

Please do NOT use the FT_PROG tool in conjunction with the MiniZed. The only way to fix it after erasing it is to send it back to the factory, which is more expensive than just buying a new MiniZed.

Hi Xuan,

It appears you wiped out the proprietary firmware on the FTDI Chip that controls the JTAG/UART Access. It is not something that is publicly published. We do not recommend using the FT_PROG tool in conjunction with the MiniZed.

Please refer to your private messages Xuan.
