Nexys Video DMA Audio Demo is broken

[bklopp]

https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-dma-audio-demo/start

Importing the project and following the instructions to the-T yields build project errors. I had to import the individual files into a fresh SDK project, instead of importing the project itself in order to get it to build and compile.

I managed to get it to run, but it after pressing the record button it never ends the recording after 5 seconds-as if the interrupt handler is never getting called.

I am using Vivado 2018.1. Any help will be greatly appreciated.

Hi @bklopp,

The projects are dependent on the version. In this case it is made in vivado 2016.4. We have not had time to update our projects to vivado 2017.4. To use this project in vivado 2018.1 i would suggest to start with fresh project using the most recent release here.  Load the project into vivado 2018.1. Next update/generate the ip cores by clicking tools->reports->report ip status. Then create a wrapper. Next generated a bitstream. Now export hardware including the bitstream and launch sdk. Once sdk is open import the DMAaudio   DMAaudio_bsp. Next program the fpga and run the application by right clicking the DMAaudio and selecting run as -> launch on hardware(system debugger). Let us know if this fixes this issue.

thank you,

Jon

Upon importing the SDK project, I get these errors:

@bklopp, you are getting version errors as expected. Use the Vivado version the project was published in and tested for. If you still want to do the upgrade yourself, this particular SDK error can be fixed by manually updating each driver and OS version to the current one, or re-creating the BSP and manually importing all the settings from the old one.

[bklopp]

I created a new empty application project, imported the folders and files from the DMAaudio folder into my project.

I could use some clarification on what you mean by "manually importing all the settings from the old one"

What settings are you referring to? The settings under the Board Support Package settings?

If so, which ones need changed to what?

 

system.mss

system.mss

It looks like the interrupt is never being triggered by the DMA. I put a breakpoint inside of the interrupt handler and it never hits it.

Hi @bklopp,

Please attach a picture of how you are connecting the Nexys Video. Also are you waiting the 5 seconds before hitting another button as discussed in 2. Recording from an input of the demo page here?  It might be easier to download vivado 2016.4 to use this demo with the version that it was made to work with.

thank you,

Jon

I followed your suggestion and just downloaded Vivado 2016.4. I tested it and it works on that version.

Hi @bklopp,

Glad to hear you were able to get the demo to work.

thank you,

Jon
