    Zybo Z7 Audio Demo upgrade

    Hi @jpeyron, Thank you for your answer. After looking in what you have suggested, I tried to implement that Instructable. I found this thread: https://forum.digilentinc.com/topic/1738-how-to-use-audio-on-zybo-board/ i did manage to get everything going in Vivado. But, I got these errors when I import RTOSDemo in SDK. I tried to Regenerate BSP and also to Change Referenced BSP but nothing changes. Thanks, Melisa

    Zybo Z7 Audio Demo upgrade

    Hi everyone, After launching DMA Audio Demo successfully, I was wondering is there any way to process recorded data before playing it back? The data is stored in AXI Instance with known number of samples (prototype of function: void fnAudioRecord(XAxiDma AxiDma, u32 u32NrSamples);) I would like to measure energy of my audio signal and show it on LEDs (for example). Any suggestions are well welcomed. Thanks in advance,

    Try disconneting your board, and connecting it again. Then check in Device Manager on which port is your board, and then connect it in SDK terminal. Program your board and then run your code. I had similar issues and this fixed it. Hope it helps

    Zybo Z7 DMA Audio Demo - not working

    Hi @ArKay99, I finally did it :). Only thing after launching SDK is to create your own dma application with dma_bsp and import demo files as File System (not existing project as written there). But I don't hear anything on headphones. I tried with line input and mic input. SDK terminal is giving messages (start recording, start playback etc.) but I hear nothing. I would appreciate if anyone has advice for this problem. Regards,

    Zybo Z7 DMA Audio Demo - not working

    Hi, Thanks for your answer. 1. I did everything that is outlined in number 1 section, and I have done every step that @jpeyron mentioned above in Vivado 2018.2. 2. I don't have that much experience with SDK, so I was wondering is it possible to launch this demo on my Zybo board only with Vivado project or it has to be launched to SDK? P.S. @jpeyron has sent me step to upgrade this project in SDK, but I didn't try it yet because of my question 2. Thanks a lot in advance.

    Zybo Z7 DMA Audio Demo - not working

    Hi, I am trying to implement Audio Demo on Zybo Z7 using this: https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-z7-dma-audio-demo/start First, I wanted to do it just using Vivado 2018.2 (without SDK). I followed what is described in this comment: Bitstream is succesfully generated with two following warnings: [Labtools 27-3361] The debug hub core was not detected. Resolution: 1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active. 2. Make sure the BSCAN_SWITCH_USER_MASK device property in Vivado Hardware Manager reflects the user scan chain setting in the design and refresh the device. To determine the user scan chain setting in the design, open the implemented design and use 'get_property C_USER_SCAN_CHAIN [get_debug_cores dbg_hub]'. For more details on setting the scan chain property, consult the Vivado Debug and Programming User Guide (UG908). I tried to fix this warnings using Xilinx and Diligent forum, but wasnt successful. Device is programmed but the audio demo is not working (when I press BTN1 and after BTN2 I can not hear anything on headphones). Any suggestions/solutions are very well welcomed. Regards,
