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

Hello - I have accidentally erased the FT2232H on my Zynq Zybo Z7 (7020).  May I please have the recovery instructions?

 

Thanks.

Hello,

I have problem with ft2232h.

I changed and erased the eeprom 93lc56. The board doesn't recognize the eeprom after.

Please tell me the solution how to do it. @jpeyron, @JColvin

Thank you

Hi @JasonMoon,

Are you using a Digilent board of some kind? Our solution is only compatible with Digilent boards.

Hi, @JColvin

I'm using ZYBO Z7-020. Please tell me how to restore it.

Thanks

Hello @JColvin,

I am having the same issue as rest of the users here. I accidentally erased the EEPROM on my "JTGA-HS2 Rev A". I have another one that works fine. I tried saving its template using FTDI's FT_Prog, but that didnt seem to work. There is a significant difference between how FT_Prog reads these two devices. Hence, Vivado no longer recognizes my "JTAG-HS2 Rev A".

After reading above comments, I tried using Digilent's Adept, but that didnt recognize it either.

Thanks in advance,

BR,

Hello @JColvin,

I join the long line of people, unfortunate enough to trash their eeprom in the attempt to enable the serial port.

Vivado doesn't like my CMOD-S7 anymore... ?

I believe I accidentally wiped the EEPROM on my ARTY A7 board. Can you help me restore it?

Hello,

luckily I found this post here. I have the same problem as most people here.
I wasn't giving attention and accidently erased the EEPROM on my JTAG-SMT3-NC through FT_PROG. It seems there is a way to restore it.

Please can someone assist me with restoring the EEPROM?

Thanks,
Jens
