I am a novice, and I would like to try with some simple layout. I made a simple I / Q signal generator, but I can not get any output on the STM32 Discovery board.
Yes, I have read all the instructions regarding the STM32F407 discovery. It's very interesting that the demo layout works fine. I unfortunately do not know how to send my layout to the forum. However, it is very simple, only SinGenFract32 connected with HV out and ledbar meter as a sink. Bit rate is 48000 and 32 bit width. No errors , but after sending to the board, nothing happens.
I see. So the demo layout works for you and you hear audio pass through? That means the issue is likely with the layout using the SinGenFract32. You can attach an image of your layout in your reply if you would like to share it on this forum.
To debug layout issues like this, it is useful to put Meter and Sink modules at different points throughout your layout to try to find where the dropout occurs.
Do you have in input pin in your system as well? If not, re-implement your simple layout above in a new layout, but make sure that the SYS_in pin goes to a SinkFract32 module. This may be the issue.
To start the layaout, press the 'Run' button shaped like a triangle at the top menu bar of Designer.
The system input pin is required by the internal system for builds. You must have it in your layout, but you do not need to use it. Simply hook up a Null Sink module to the output of the SYS_in pin and design the rest of the layout however you'd like.

Glad to hear you got it working.

Incase of above layout, why we have to use SYS_in pin?.
I also would like to use sine wave generator as the input some thing like below. Could you please help us here
sine wave generator -> LPF -> File dump
