    Press reset on the board and if you still see strange characters review PuTTY Configuration for com4 as suggested

    If you are testing with putty and the JTAG selected your are not going to see anything until you program the board I think

    please check the bellow video. In it, they have shown that you can access UART in JTAG boot mode via puTTY terminal. The SD card already has linux install in it.

    Yes, what I say is if you haven´t programmed anything that sends data through the uart you  are no going to see anything

    Vitis has a built in serial terminal included in its Debug view. Close any putty windows and from Vitis using the search field look for Serial Terminal, create a new one and adjust com and baud rate.

    Then try to program your board.

    In my case I have problems with JTAG if I have connected my Digilent Analog Discovery II that has an Spartan 6. I have always need to disconnect it before programming the minized.
