  1. I am trying to generate a signal off the audio output of pynq z1. For a while, I had a board and it was working fine. Then suddenly it stopped working. I tested everything is ok. I send the right PWM signal to the output. But no analog signal is detected from the audio output. I thought maybe the board hardware is damaged. So I buy a new board. But still I cannot get any analog signal from audio output. Any clue what may be the problem?

  2. I just got the Eclypse z7 board. Installed Vivado 2019.1 and built and compiled DAC demo. When I try to program the FPGA I get a message done pin is not high on target fpga. I tried making a simple hello world program and it give me same message although it print the0 "hello world" message on the UART terminal. But I do not see any output on DAC. Any clue what might be the problem.
