Recording never stops in Zybo Z7-10 in Zybo Z7 DMA Audio Demo

[vivekmishra01]

I am trying to this project from https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-z7-dma-audio-demo/start . But form me recording never stops. I also, took reference from the above link of Christian, but it's still not working for me. Can anyone help to fix this thing for me. My issue is same as Christian. Also can anyone help me to set J5 to JTAG. Playback is going well, but recording never stops. Please check the images attached.

Hello,

I have asked another engineer to take a look into this thread.

Thanks,

Hi @vivekmishra01

Which version of the tools are you using? I haven't managed to reproduce the issue in 2018.2 (and don't have 2016.4 installed), but assuming that you are using the 2016.4-2 release, there's some possibility that adding the following line to the demo.h file might help:

#define DDR_BASE_ADDR       XPAR_PS7_DDR_0_S_AXI_BASEADDR

Alternatively, you can try this version: https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/demos/dma-audio

Thanks,

Hi @artvvb

I tried from the alternate link.https://reference.digilentinc.com/reference/programmable-logic/zybo-z7/demos/dma-audio

I have tried with Zybo-Z7-10-DMA-2018.2-1.zip on this link https://github.com/Digilent/Zybo-Z7-10-DMA/releases/tag/v2018.2-1?_ga=2.29388476.2004444360.1618414611-1252808221.1617825139

But for this also, I am facing the same issue.

My vivado version is 2018.3

I tried both with Line-in and mic for recording, but for both the buttons, it hangs.

The problem is fixed by setting J5 to JTAG. Now recording stops after 5 seconds. It was so frustrating. Below is the steps to set J5 to JTAG. I did it with the help of my classmate.

To change the JP5 jumper:
Pull the blue jumper cover up and off of the pins, then place it back down across the two right-most pins.
