Hey,

I want to analyze a Wi-Fi signal with the zcu111, but can't figure out how to reach the max sampling frequency of 4096. Cloud you maybe provide me some assistance with that?

Hi,

since the zcu208 rfsoc is supported officially in pynq. you consider to add support for this dev board?.

With or without the CLK104 board.

Hi,
I am experiencing strange behavior of the spectrum analyzer overlay implemented with the RFSoC2x2 module. Regardless of whether the inputs are connected or not, I observe a signal about 100 MHz wide on the spectrum. I am using a standard, freshly installed image version 2.7.
Additionally, when I turn on the spectrum analyzer, the program stops working. The spectrogram cannot be turned on. The signal spectrum is static, it does not refreshing.
For comparison, I have no such problems on the ZCU111 module.
Are there any additional tools to verify correct operation of the module?

I want to compile this project completely for ZCU216 kit. Can anybody list the detailed instructions to do this ??

Hello,

I've tried viola without my board having internet access. It pulls up the loading screen but then afterwards nothing shows up. Has your group tried viola without internet access? Is there a way for this operate without internet?

thank you.

Dear @dnorthcote / @LewisMcL / @lbrown65 ,

I'm working on developing a spectrum analyzer using the RFSoC 4x2 board in conjunction with MATLAB. I'm aiming to increase the FFT size to 16384 samples for improved frequency resolution, but the current maximum in my implementation is 8192.

Specific questions:

1. Feasibility: Is it technically possible to achieve an FFT size of 16384 on the RFSoC 4x2 using the available MATLAB IP? Are there any hardware or software limitations to consider?
2. Approach: If feasible, could you please guide me on the steps or modifications I need to make to my current implementation to achieve this 16384 FFT size? Are there specific code changes, configuration adjustments, or alternative IP blocks I should explore?
3. MATLAB IP: If you're familiar with suitable MATLAB IP options for this purpose, any recommendations or insights would be greatly appreciated.

Hello,

Thank you so much for providing the VHDL code of this project. I watched the youtube video (https://www.youtube.com/watch?v=PqPdfnbNxyY) where you described the block design of the project (rfsoc_sam.xpr). However, I couldn't fine the corresponding file in this github repo. Could you please upload it as well?

Thanks,
Ali

The following does not work for XUPRFSoC board ...

# check whether board is supported
def check_env():
    if not board == 'ZCU111':
        raise ValueError("Board {} is not supported.".format(board))

I get this error when trying to PIP install on the XUPRFSOC board ...

I'm currently working with your Pynq image 2.6 and have successfully implemented the rfsoc_qpsk build. I'm wanting to implement the rfsoc_sam but my ZCU111 does not have a WiFi dongle and I am unable to create a shared internet connection. As a result, the I cannot do a pip3 install of the repository, is there a PYNQ image containing this build already on it like the rfsoc_qpsk? Or, is there a way to target the ZCU111 with the bitstream?

Hello,

According to PYNQ website, they used Vivado 2020.2 for Pynq 2.7. However, when I ran rfsoc_sam, seems like you guys are still using vivado 2020.1. Will there be any compatibility issues with Pynq 2.7 and Vivado 2020.1? Will you be upgrading to Vivado 2020.2?
