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

I think I accidentally reprogrammed the FT2232 chip on my Arty S7 board. Any chance to reprogram the chip?

Best regards,

Hi, I think I am having the same issue as others here.

While I was programming a custom FT232H based board, I had my HS-2 programmer connected as well - and now it shows up with the same configuration as my custom board.

Is there a way to restore my HS-2 programmer? Thanks for any assistance!

I'm having the similar problem i accidentally erased EEPROM attached to the FT2232 device on JTAG-SMT3-NC.

Could you help me to restore the EEPROM?

Hi,

 

it seems I managed to erase the eeprom on my HS1 as well. ?

Can you help me?

Hi,

I have the same issue with the XILINX Digilent Genesys2 board. I erased by mistake the EPROM.

Can I please have the restoring instructions, too.

Many thanks,

Hello,

I am having a similar problem where I have accidentally erased the EEPROM on a JTAG-SMT2-NC. Can you help me with restoring it?

Hi,

I'm afraid I did the same fail with FT-PROG on my arty-a7 ? Could you help me revive the operations with Vivado?

Hello,

Through the miracle of lack of sleep i've managed to erase the EEPROM on my JTAG-SMT3-NC... i know.. not great...

Any solutions to get it up and running again?

P.S. if anyone uses these modules... don't mux this board with other usb ICs... it doesn't end well quite fast :)

Thanks.

Hi @jfranz-argo, @kharoonian, and @Franky32,

I apologize for the delay. I have sent each of you a PM about this.

Thanks,
JColvin

P.S. to other readers, be sure not have Digilent boards attached when you are reprogramming other FTDI devices. A long list of users will tell you it's an easy mistake to accidentally select the wrong device.
