Hmm some of the confusion here might be , per the comments in xdc file, the ja references in the XDC are numbered differently to the corresponsing JA references on the schematic. ie ja[0] in the XDC appears as JA1 on the schematic, i.e. the ja numbering goes [0:7] in the XDC but those 8 lines map to JA[1:4] and JA[7:10] since JA[5:6] and JA[11:12] are used for pairs of VCC and GND connections on the PMOD connectors, i.e pins 5 and 11 are GND and pins 6 and 12 are VCC3V3 on JA

Thanks for posting the update, I was just about to do so myself :). I want to reiterate that any unwanted effects of Zadig can be undone and the driver removed by persistently looking for 'libusb-win32 devices' appearing in Windows Device Manager (WDM) as you attach your board and then selecting both 'uninstall device' AND 'uninstall driver' , then after it seemed to complete ,disconnecting and reconnecting your board to see if it reappears , if so, repeat until it does not. You have to to this seperately for every USB port you ever connected to. Note - when you expand the drop down for 'libusb-win32 devices' you will see it twice as in 'interface 0' and 'interface 1' , so repeat for both. Note - on my machine 'libusb-win32 device' which starts with an 'L' was as appearing between Keyboards and Memory devices in WDM rather than under USB where you might be thinking to look for a USB device you just plugged in . I just operated on a similarly affected colleagues PC and both machines are now doing well lol !

Update - I found a link to an article 59128 about reloading the cable drivers for Digilent under Vivado and tried running the batch file but it has made no difference , my problem persists. 59128 - Is it possible to (re)install the Xilinx USB/Digilent cable drivers without a full reinstall of Vivado Design Suite? I am thinking of uninstalling the usb driver in windows device manager where it is currently displaying the USB connecytion as the Trion T20 but where do I find the correct Digilent Eclypse driver to then install?

Thanks for the inputs. I tried running Adept and unfortunately it is not recoginising the board

I had been using my ECLYPSE Z7 board successfully for several months until I had to switch and work for a few weeks on a different non FPGA related project. I have been using Vivado v2019.1 to develop my project . Today I tried to reconnect to my ECLYPSE Z7 board through Vivado hardware manager >open target so I could load and run my code but Vivado is refusing to connect to the board, reports unconnected. When I check in Windows Device manager to see if it sees the Eclypse Z7 board being connected on USB , Window's Device manager says I am plugging in a Trion T20 board?? I played with one of them last year before I moved to the ECLYPSE Z7 with the ZYNQ-7000 processor but have not connected to it for over 5 months . I do not understand why Windows is wrongly recognising the ECLYPSE board as a Trion T20 board. What got broken and how do I fix it so I can talk to the ECLYPSE and run my code ? Note I was not using Vivado to talk to the Trion board it had some other software. So I don't think it is Vivado that is getting confused, it must be a Windows thing :(. I am running Windows 10PRO v22H2. Thanks Mike
