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

Hi,

I have the same problem. I achieve to fix JTAG side with the fmt1 recovery procedure from an other digilent forum, but I unfortunatly lost the UART side maybe because fmt1 is not build with FTDI 2232...

Please, help!

Hi @julienV,

I am a little confused. Do you perhaps mean SMT1 rather than fmt1? Or, I suppose more specifically, which Digilent board are you working with?

I'm not certain which recovery procedure you are referring to since the one I am thinking of would have been sent via direct message and not posted (at least as far as I am aware of).

Thanks,
JColvin
