Board v3c shipped with PID=0x7780

Postby jluc » Tue May 23, 2017 4:59 am

Hi all,
I just received a v3c board, but installing drivers fails. It appears the board was pre-configured with VID=0x403, PID=0x7780, and not the usual PID=0x6010. This is confirmed by lsusb on linux and usb-view on Windows.
FT_Prog fails to scan the device and consequently I cannot reprogram the EEPROM of the FT2232...
Any hint on how to change the PID ? (beside asking WHY my board was shipped like that...).
Thanks.

I see someone else had the same problem: https://forum.creatordev.io/t/bus-blast ... ems/237/18 Probably some problem on the sourcing end.

If you have any other SPI adapters, you can use it to erase and reprogram the EEPROM via JP3. But I believe that it's already empty. Can you verify this?

I could successfully change the PID using ftx_prog on linux (specifying the old PID). My board is now detected under Windows as well. I could write the CPLD from Linux and it now works like a charm.

Glad you solved it. Can you post the command you used over here? It may help other people as well.
