Hi, I have a similar problem with my Nexys Video. It was fine yesterday, but today, suddenly, is not working anymore. Vivado, in the hardware manager, is able to recognize the board but unable to effectively open the target (the error " [Labtools 27-2269] No devices detected on target localhost:... " is reported). Similarly, the Adept software recognizes that it is a nexysvideo but the initialization failed (in the console I read " ... Found device ID: ffffffff, Found device ID: ffffffff, Initialization Failed. "). I already tryed to use Vivado in another pc or with other cables and it gives back the same error. Is it possible to recover in some way the board? Regards, Carlo

Hi Zygot, thank you very much for your support! In my project I need 20 I/O single-ended signals (in particular I need 12 inout, 5 outputs and 1 inputs plus an input and an output clock) in the order of 8 MHz, a USB-UART and an ethernet port. Do you have (or any other user has) an FPGA board to suggest?

Hi Zygot, thanks for your reply. I saw from the schematics that most of the FPGAs have not the protection resistances on the PMOD differential pins, so they should better for high speed signals. However, in my project, I have to use the output pins as single-ended, is it possible and "safe" to do this with differential PMODs? In your past projects did you ever use them as single-ended? Did you see unwanted cross-talk effects? Regards, Carlo

Hi all, I am interested in Nexys A7-100T FPGA board. In the datasheet I do not find the maximum recommended frequency for input and output signals, trough the PMOD pins. I need to handle signals in the order of 10 MHz. Does anyone know if the PMOD pins of Nexys A7-100T are capable to correctly handle this frequency? Which is the maximum recommended frequency? Thank you in advance! Regards, Carlo
