How to restore FT2232 EEPROM back to factory settings?

[mixsemi]

Hi Everyone,

Just accidentally flashed the EEPROM attached to the FT2232 device on the Arty. The board is dead without the USB connection. Been using for 2 months without issues until today.

In Vivado it is showing:

 "ERROR: [Labtoolstcl 44-469] There is no current hw_target.". 

when trying to Auto Connect with the target in Hardware Manager.

Within FT_Prog (FTDI's flash tool), the registers (e.g. serial number, vendor ID, D2XX/VCP driver ...) can all be read and modified. How can it be restored back to Digilent factory setting? Is there an FT_Prog template that we can use?

Thanks,

Robin

Thank you very much! It's working again! 😃

Hello, JColvin!

I am facing the same issue. I'm using the Genesys2 board, and I have incorrectly programmed the EEPROM of the FT2232H, which now prevents access from Vivado. Could you help me?"

Hi JColvin,

Good morning!

I have same problem for my Cmod_A7 dev board, Vivado can't recognize it again after FT_PROG programmed. Could you help me?

Dear,Engineer and friend:

   my chip is FT2232HL which is used to program Xilinx XC7A15T with openOCD, I rewirte the EEPROM Product Description and Manufacture with MProg, and the FT2232H could not be identified by computer(win10-64) any more. please email me this program or some way to re-write the FT2232H.

yours

Jack

Hi @CJtech2023,

Which Digilent product do you have? Your screenshots indicates that you might have the Nexys 4 DDR board, but you also mentioned having an Artix-7 15T FPGA, which is not present on any of the Nexys boards. I want to make sure I do not give you faulty instructions to avoid any chance of accidentally damaging the device.

Thanks,
JColvin

Hello, JColvin. I have a problem here. I used FT2232HL development board to burn the firmware of FT232, but now I cannot recognize the development board of FT2232HL normally. Now I want to ask how to erase the firmware burned before.

[JColvin]

Hi @dsdsd,

From what I can recall, no Digilent device uses a FT2232HL. Digilent's programming solution is made exclusively for Digilent boards and so will not be able to restore a different development board from a different manufacturer.

In terms of just generically erasing material, FTDI's FT_PROG application may be able to help you, though it is also likely a common reason for the many users that ended up posting on this thread to begin with.

Thanks,
JColvin

Hi JColvin! how to flash the eeprom of FT2232 to make it work on the way of jtag？I flash the EEPROM by the FT_Prog，but I cant scan the FPGA by Vivado😮‍💨

[JColvin]

Hi @lee123,

Are you using a custom board and want to license Digilent's solution on how to get Vivado to recognize the board, or do you already have a Digilent board that you erased the EEPROM configuration on?

Thanks,
JColvin

[lee123]

I have a Digilent board and It was normal until I made a mistake with the EEPROM configuration；Now,I cant connect the board.

[JColvin]

Which Digilent board do you have so that I can provide the correct instructions?

Thanks,
JColvin

[lee123]

Arty A7

Thanks,

Hi @lee123,

@JColvin can you provide me with the EEPROM configuration instructions for a Genesys 2 dev board?

Also, is it possible to make any configuration changes to the EEPROM without erasing the jtag functionality? I want to use the non-jtag channel on the FT2232H for data transfer in 245 FIFO mode with the FTDI virtual COM port driver. This is referred to in the Genesys 2 manual in section 10. PC - FPGA Data Transfer (DPTI/DSPI). I think I need to reconfigure the FT2232H EEPROM to do this. I tried to make the necessary configuration changes and it caused my board to stop being recognized by Vivado.

Thanks!

After using FT_PROG to re-program the device, the Hardware Manager Vivado cannot find the target.

@JColvinCan you send me the instruction to restore the EEPROM configuration on Arty A7 board?

@JColvin Can you support me on this question?

[Hernanrl1]

@JColvin Likewise, I used the FT_PROG program and after that my cmod s7 board is no longer recognized by the vivado program, how can I solve this problem?

[JColvin]

Hi @lhphuc_mrvl and @Hernanrl1,

I have sent you both a PM with some instructions.

Thanks,

Hello,

I have an Arty a7 35 board (rev. E) and seem to have some issues with the FTDI chip too. I have not erased the EEPROM, but somehow I get wrong data when I try to use the USB as uart input for my FPGA. I also have a different FPGA (ulx3s, which has the FT231XS chip) and there my design works as intended.
I cannot pin down the problem at the moment, but maybe reflashing the EEPROM might be one step closer to finding the problem and exclude that from the possible problems.

So is it possible to get the instructions, too? Thank you!

[JColvin]

Hi @BlazeIt,

I suspect this may more likely be the source of a different issue (driver, baud rate, etc), but I have sent you a PM.

Thanks,
JColvin

Hello,

I have a zybo z7-20 that is no longer recognized by vivado.

Would it be possible to get instructions on factory resetting the board?

 

Thank you,

Eric
