Zynq7 Processing System UART problem

Hi,

 

I'm designing with Zynq and encountered a problem.

The target is to configure a project, to export it to SDK and to print "Hello world" using UART.

I took reference design that works and 'minimized" it, i.e. just  Zynq7 Processing System IP, DDR external ports, with UART and ENET enabled only. I do synthesys, export hw to SDK, create "Hello world" project and it prints "Hello world" on Terminal window.

When I create a new Vivado project, with exactly same block diagram, with identical settings, it doesn't work, the Terminal window is empty.

 

Thanks for help.

The problem solved, the difference was in DDR Configuration, DQS to clock delays.

Hello  ilya1976,

 

Can you please explain in detail what you changed exactly, because I still get can't see nothing in the terminal when I use the more advanced examples in that tutorial?

 

Sincerely,
