    Zynq book - tutorial 5 Zybo Z7

    Hi @Ciprian, Yes, I tried to change dimension of the RecSamples, that is why I had the same problems as you. Thank you Yes, my idea is to put Sine Wave through PC via Line in, and then record it. I have been playing around with it and have more questions if you can help me. I wasn't able to find a way to store or see all 48000 samples, I have tried to save that variable into binary file, and I have also tried to put it as output in XSCT Console (reference: https://forums.xilinx.com/t5/Xcell-Daily-Blog-Archived/Adam-Taylor-s-MicroZed-Chronicles-Part-233-Zynq-SoC-XADC/ba-p/824170), but both ways are not working. When I try to store it as a binary file, command is executed, but I can not find file. Other way, as a output in XSCT console, I can see the data but I can not copy it from there. Sorry if this is some beginner mistake. Anyway, thank you very much for all the help provided. Regards,

    Zynq book - tutorial 5 Zybo Z7

    Hi @Ciprian, Thank you very much for your time and help. :) I tested it and it is working properly. So, I don't want to make anything more that putting my code for FFT and calculate FFT on that array. I have one following question - when I enter debugging mode, program stops at init_platform(); I left out the buttons part. Also, I am thinking if I put sine wave, and then take results of array - I can plot them using MATLAB/Octave so I can check if my data is correctly sampled. Is this right approach and did you face any problems with debugging mode? Thank you again for everything, Regards,

    Zynq book - tutorial 5 Zybo Z7

    Hi @jpeyron, I tried to follow your advice using IP core from that demo. I couldn't find any documentation, but from the demo I tried to figure out how to configure it. This is my block design (basically I just replaced zybo_audio IP core from the book with the one from demo): When I export my hardware, I first ran helloworld and it worked. However, when I try to run it with configuration I did for streaming the data, it hangs (it does nothing, program does not start at all). Can you help me with this? Regards,

    Timing constraints are not met.

    Hi @greedyhao, After you have done that, have you re-run the implementation?

    Hi @jpeyron, Hope you will find time soon to help me with this. Regarding DMA Audio Demo, I find it a bit hard and complicated for taking and processing audio data. I have already tried with it, but this Zynq book tutorial is more simpler and easier for beginners. Hope we will find solution to it Regards,

    Timing constraints are not met.

    Hi @greedyhao, Go to Implementation -> Edit Timing Constraints -> Set Clock Groups Then another window will open and you just have to put the names of clock there: Hope this helps.

    Timing constraints are not met.

    Hi, I also did tutorials but didn't occur this problem. However, you can set false path or create clock group to fix your timing error. Reference: https://www.beyond-circuits.com/wordpress/tutorial/tutorial16/

    Zynq book - tutorial 5 Zybo Z7

    Hi @jpeyron, Here it is. Thanks. adventures_with_ip.xdc edit: I have noticed the following - I program the board and Run As -> Launch on Hardware(System Debugger) and nothings happen. Then, I turn on and off board, and run program again without programming the board and I can hear sound. Also, if the board is turned off, some strange noise can be heared. If someone can help me, I would appreciate that. Regards

    Hi @jpeyron, In the attachement is my block design. I just want to stream audio data. Also, I have attached my code and here is SDK log. 21:21:55 INFO : Registering command handlers for SDK TCF services 21:21:55 INFO : Launching XSCT server: xsct.bat -interactive C:\Users\melis\Downloads\exercise5.xpr\exercise5\exercise5.sdk\temp_xsdb_launch_script.tcl 21:22:00 INFO : XSCT server has started successfully. 21:22:00 INFO : Successfully done setting XSCT server connection channel 21:22:11 INFO : Successfully done setting SDK workspace 21:22:11 INFO : Processing command line option -hwspec C:/Users/user/Downloads/exercise5.xpr/exercise5/exercise5.sdk/design_1_wrapper.hdf.

    Zynq book - tutorial 5 Zybo Z7

    Hi, I have been following tutorials from Zynq book for Zybo Z7 board. In tutorial 5, where the zybo_audio_ctrl IP core is used, I can not get any audio data through my board. The tutorials are made for Zybo board, and I followed migration guide (to Zybo Z7), but still no success. Any help would be appreciated. Thanks
