It does not matter which operating system I am working in, EITHER windows 10 or ubuntu 18.04.
I have made sure that I have loaded the proper board file. Recently downloaded it and then I opened the xml file to make sure that it was referring to the zc7020.
When I check the ip in the block design, it shows a number of ip peripherals checked.
I'm using vivado 2019 and SDK 2019.
I followed the directions given in the post quoted below, for creating a bitstream in vivado and launching the SDK.
Programming the FPGA shows an acknowledgment that the FPGA was programmed successfully. In addition, the "DONE" light on the zybo board is lit after the programming step, so I know that the FPGA at least thinks that it is programmed with something. That does imply that PC to board communication is happening. I know that when the FPGA is programmed the software checks to see if the FPGA on the zybo is the one that the bitstream is written for. Therefore, I know that there is some backward communication, from the board to the PC.
I did choose the "Hello World" application program.
On the linux machine I am connected to "/dev/ttyS0 at 15200". On the windows 10 laptop I am connected to "Com 8 at 115200".
After run as -> launch on hardware, I see no "Hello World" in either the console window or the SDK terminal. I get no errors.
Please help. I am out of ideas at this point.
