Zedboard starttup guide tutorial for Linux

carlitos.cespedes@gmail.com


Would like to develop on Zedboard under a linux environment. However I have had problems for setting JATG cascaded mode and programming FPGA from SDK.

Can you please provide a guide, driver and setup instructions for developing for the Zedboard under a linux environment?

    The posts dont help.

    I cannot see any console output from my Zedboard device on ttyUSB0 port.

    I watched dmesg output to determine /dev/ttyUSB0 is the proper port for minicom.

    carlos@Bulldozer:~$ dmesg | grep tty

    Every time I power cycle the ZEDBoard I get the FTDI USB SErial converter attached and "now disconnected" messages.

    This makes me suspicious but not sure what is going wrong here.

     

    I also followed this tutorial and installed Digilent Adept 2 runtime, utilities and was able to see my ZED device listed. So I know my device is alive, UARTing and connecting properly.

     

    Really need help. I have tried on both windows and Linux platforms and I cannot connect to micro USB port.
