Hello, I have a Zybo Z7-10 board, where the USB port does not seem to work at all anymore. Af far as I can remember I used it 2 Years ago and back then I could at least connect via JTAG to the Vivado HW Manager. But right now UART and JTAG do not work. I also tried the provided binary from this thread (https://forum.digilentinc.com/topic/20132-zybo-z7-usb-uart-no-longer-recognized-by-pc/). And even the "DONE" LED does not turn on. When I boot from QSPI and start the pre programmed demo, the board lights up and all the LEDs are flashing. So the board seems to work in general. But als during the QSPI demo there is no serial connection. On my host PC I don't see any message in dmesg as well. Is there anything that I could try to make it work or debug the issue further? Regards, Erik
Hello Everybody, I am new to the forum, and I am about to ask a question about a problem with my new Arty development kit. I have installed Vivado succesfully. When I connect the board for the first time, after installing the whole software, windows is installing drivers for the board, but fails in retrieving one of them (USB serial driver (COM1)). As a result, when I start Vivado and I try to open the target I get the following error: ERROR: [Labtoolstcl 44-26] No hardware targets exist on the server [localhost] Check to make sure the cable targets connected to this machine are properly connected and powered up, then use the disconnect_hw_server and connect_hw_server commands to re-register the hardware targets. I have looked around for a solution but didn't find anything. Does somebody already had this error? How can I solve it? I have already tried to uninstall Vivado, restart the PC and install it again, but didn't work. I also tried to install the cable drivers manually from consolle, but I am stuck witht the problem. Thanks in advance for your help and time. Giovanni.
