  1. Dear Support, I am trying to implement a Microblaze in the Arty S7 with 50T FPGA board revision E. (yes Rev E not B). I instantiate GPIOs, Switches, LEDs, pushbuttons, UART and SPI at J7. I want to write c code to control the LEDs and talk to an SPI device. Attached is my implementation in picture format. The design verifies, synthesizes, and implements, but I get timing is negative. ISSUES 1. I am not sure how the GPIOs route from the block diagram to constraint file. I downloaded the constraint file, and uncomment the clock, and GPIO switches, etc...However, in the blo
  2. Anyone else experienced a problem with communicating to an HP laptop running Windows 7 SP 1 from an Arty S7 50 through the UART port? I boiled the application down to just two simple modules, but I still get an extra character (x"FF") added to every character sent from the board to the laptop. In other words, trying to send "01234" from the board results in "0ÿ1ÿ2ÿ3ÿ4ÿ" being received (ÿ has ascii value xFF). I've tried reinstalling drivers using files from the FTDI site, and tested with two different terminal programs (PuTTY and Termite), but the result is always the same. Communica
