  1. Hello,

    When I following The Zynq Book Tutorials(exercises 5b) , I met a error unfortunately. It says that 'Timing constraints are not met.'.

    I have no idea how to solve it. Could anybody do me a favor.

  2. Hello,

    I am new in zybo.

    I am using Vivado 2018.2. The platform is Ubuntu 18.04.

    I met a trouble when I following the Zynq Book Tutorials, the first exercise , step by step. The tutorial seemed to be fine before I launched the program on hardware(GDB).  The LED didn't blink at all.  I googled for a while, but no results
