How to restore FT2232 EEPROM back to factory settings?


Question

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 @JColvin, @Bianca

I accidentally modified the EEPROM of my device "Xilinx Kintex UltraScale FPGA KCU105 Evaluation Kit" via FT prog software. I have changeg values in "Produc Desc" and "Manufacturer Desc" fields and now, Vivado 2021 ISE don't recognize the FPGA to program it trough the hardware programmer. 

May I please have the recovery instructions?

Thank you very much.

Hi @druiz,

I'll have to find out which Digilent programmer the KCU115 uses before I can help you; UG917 from Xilinx unhelpfully just calls it a "Digilent onboard USB-to-JTAG configuration logic module". I'll post back here once I learn what it is.

Thanks,
JColvin

Help, I was using FTDI FT_PROG to reprogram the uart chip on an fpga board and I forgot that my JTAG-HS3 cable was still attached.  I erased the JTAG-HS3 cable by mistake. 

Can I get an FTDI template file to reprogram my JTAG-HS3 cable?
