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

Hi.

Similarly to original poster vivado doesn't recognize my arty7-100t and with FT_Prog i can read serial number, vendor ID and other parameters. How do i make sure problem doesn't lie there and how do i reset it if needed? 

Thanks.

Hi everybody,

I have been using zybo z7-20 and I have erased the EEPROM. Please help to retrieve it.

Hi @JColvin,

I have same problem in Digilent Arty A7 board.  Can you share the instructions?

Thanks

Hi @JColvin ,

I'm having the same problem. I accidentally erased EEPROM attached to the FT2232H device.

please guide me to restore EEPROM.

I have Arty board!

Hi @JColvin,

I have the same issue with the FT2232H device. Can you please advise how to restore the data?

Thank you!

[JColvin]

Hi @Brian Hook,

Which board do you have?

Thanks,
JColvin

[Brian Hook]

@JColvin It's on an old JTAG-SMT1

Hi, @JColvin

I'm using the original ZYBO. Please tell me how to restore it.

Thanks, 23LbBass

Hi. 

Could you send me the instructions too?  (and sorry for double posting, I'd not seen this thread.  I was pointed to the other one by someone else).

Someone has reprogrammed our prom with stuff for a MicroSemi programmer.

Thanks.

Chris.

Hi @Sundance_Chris,

To confirm from your other post, you are looking for instructions on reprogramming the JTAG SMT1?

Thanks,

@JColvin That corect.

We have a "XMOD EEPROM" from Trenz that someone has reprogrammed with FlashPro 5 ID content.  Don't ask me why.

They pointed us to you sayng:

you can download a recovery tool there: (you need google login)

https://forum.digilentinc.com/topic/1816-digilent-smt1-recovery/

select SMT1 and reflash, this should recover the license back to XMOD

 

 

Thanks.

@JColvin Fantastic.  Thanks!

 

It was nice and simple, and we can now see the Xilinx devices in the JTAG chain. 

Thank you for your help.

I also accidentally rewrote the FTDI chip on the zybo z7-10.
Can you tell me the solution?
I'm sorry I'm not good at English.

Hello,

I'm having the similar problem. I accidentally erased EEPROM on Digilent HS2 JTAG Rev. A.

Could you help me to restore the EEPROM?

Best regards

Hi @JColvin

I have issues connecting the JTAG-SMT3-NC to my Xilinx FPGA and would like to reset the EEPROM to factory defaults (digilent board not being detected by Vivado 2020 on Windows 10 platform). The board where it is placed on also contains some other FTDI devices that were programmed using FT_PROG. Possibly, our operator wrongly overwritten the Digilent board's EEPROM. Device manager shows me the UART (how would it have to show the JTAG?).

Could you provide me the instructions to reprogram the EEPROM?

Kind regards,
Dave G.
