Reset Board ID after accidental erase in FTDIprog?


mfarrar

Question

Hello,

I recently was exploring with my ArtyBoard and whether the FT232HQ chip could allow for reconfiguring of the Port B for use as a USB 2.0 (D2XX driver) for faster data rates (several MBaud vs. <1 MBadu) than a virtual COM port would allow. In the process, it looks like I have lost the Arty board signature of my device. I have 2 Arty Boards, and when I compare the "Device Output" of the unmodified board, I see some output above the identification of "Digilent USB Device" which looks something like (....V...5j .Q...rAyt" etc. The modified device now only shows a "V" and the "Digilent USB Device" output. As a result, Vivado is no longer seeing the device.

1) Is there any way to reprogram the FTDI chip to include the device ID so that it can be recognized by Vivado? I can provide device serial number if that helps.

2) Is there a way to accomplish my desired goal without having this happen again?

 

Thanks,

Matt
