How to restore FT2232 EEPROM back to factory settings?

mixsemi · November 29, 2016

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 from me as well @JColvin

I am having trouble with the FT2232 chip as well, but am unsure what exactly the issue is. First it would only be detected in Vivado, but I got no serial ports in Device Manager. After removing the device from Device Manager, the serial port works, but now the board is invisible to Vivado.

The EEPROM content, as exposed by the FT Prog program, is:

Device: 0 [Loc ID:0x111]

Hi @JColvin,

I have an ArtyS7-50 Board with the FT2232 chip on it. After changing the JP1 jumper position while the board was running it now isn't recognized by Vivado any more. The FPGA itself still works fine from SPI flash.

Would you please provide me with instructions, how reprogram the EEPROM of the FTDI?

Best regards,

Christan

Hi @DaveGeerardyn-AS,

I have sent you a PM with some instructions.

-------

@jb9631,

Which board are you using so I can provide the proper instructions?

-------

@cbmarco,

I'm surprised to hear that this is what caused the issue on the Arty S7. Changing that jumper only affects how the FPGA device is programmed on power-up (though you can still reconfigure the FPGA via a bitstream if the jumper is set and the device was already reprogrammed over flash (and I'm presuming that you did not change the jumper in the middle of the configuration process).
My gut reaction to this (I don't know what you have already tried, so maybe this is not the case) is that Vivado has not released it's previous connection to the device. I would recommend either restarting Vivado or checking the task manager (presuming you are on Windows) to see there is an active hw_server process running and then kill that process so that Vivado "releases" its previous JTAG access.
If this does not resolve the problem, let me know and I can provide some further instructions.

--------

Thanks,
JColvin

cbmarco · June 30, 2022

Hi JColvin,

sorry, my bad. I was trying to program the FPGA under Linux without Vivado using openocd-0.11. At first I succeeded two times using "sudo openocd ...", then I changed the jumper, changed the command and continued without sudo. So the program didn't find the board anymore and I thought something would be damaged. In fact openocd was missing the rights to access the USB. Then I tried with my Windows Vivado installation. It didn't recognize the board.

Then I transferred the EEPROM Contents of a second Arty S7-50 board to my first board with an old installation of FT_Prog_v3.6.88.402.

Later I found out my Windows Vivado doesn't recognize any Boards. On a second Windows PC our second board is recognized fine, while the first board now isn't recognized by any Vivado any more. And I found I still can program the first board using "sudo openocd ..." under Linux.

So what's the missing magic to make my board appear as a programmer in Vivado again?

jb9631 · June 30, 2022

Hi @JColvin thanks for the response. I'm using an Arty S7-50 board. Revision B, I think, if my eyes can read the silkscreen correctly.

I've found a relevant procedure over on GitHub (link), where somebody has shared a working dump of the FT2232HQ EEPROM, and flashed it using `ftdi-eeprom` on Linux. Still, if you would be kind enough to forward me the proper procedure, I would be delighted.

Thanks in advance

Felippe · September 2, 2022

Hi everyone, I did the same mistake with a FT4232H embedded in the Xilinx Virtex UltraScale+ VCU129, mistakenly programmed using the FT_progr and losing the serial number descriptor.

Can someone provide me support to have Vivado recognizing the chip again?

Thanks,

Felippe

goodness24 · December 19, 2022

Hi, I accidentally lost the FT2232H EEPROM information of my Cmod A7-35T board, and Vivado did not recognize the board anymore. It seems a common problem here. Can you give me your advice to recover the information? Thanks, Goro

Dvir · December 26, 2022

Hi,

I accidentally change the VID and PID with FT_Prog and cant restore to default value.

Now when I try to scan in Ft_Prog I see

“no devices found” and cant change the VID and PID cause its I did not see nothing

Please help me how to restore to default value of Ftdi to read from EEPROM the default values

JColvin · January 3, 2023

Hi @Dvir,

Which Digilent JTAG programmer are you using so I can send you the correct instructions?

Thanks,
JColvin

Hi Everyone,

I have a BASYS-3 board and I have the same issue.

By mistake i have changed the config of FTDI FT2232H eeprom. And now Vivado doesn't detect the FPGA.

Is there any way to restore the FT2232 configs to factory defaults? Please help.

Thank you.

I accidentally overwrote the firmware of the JTAG HS2 cable. After the accident, JTAG HS2 cable is not recognized.

I'm afraid i must also ping @jcolvin :(

i have a Zybo z010 Rev B (2013) booting it up i have a PGOOD light and no DONE light and can't see it as a device on any combination of machines, ports, USB cables etc.

Hi, @JColvin

I accidentally erased the EEPROM on my "JTAG-SMT3-NC".

Now the system sees the device with ID ffff:fffff

Can you please PM me instructions to correct it? Thanks.I accidentally erased the EEPROM on my "JTAG-SMT3-NC". Can you please PM me instructions to correct it? Thanks.
