  1. I'm running the Nov. 18 build of Vivado 2015.4 (not 2015.2) and it runs fine. It got synthesis and implementation licenses successfully.
  2. I have a new Windows 10 laptop to host my new Arty. The first time I plugged in the USB the Arty's 7A35 FPGA appeared as expected in Vivado HW Manager. I programmed the FPGA apparently successfully, but then the laptop crashed with an error starting with ftdi. Now when I plug in the USB, Vivado HW Manager does not recognize the Arty. Windows Device Manager lists the Digilent USB device, and reports a driver error. Driver properties reports "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)" Is there a device driver for Windows 10 I should install now? Thanks! --Mike
