    I am using the CN0540 with a DE10-Nano, If I use a Kuiper Linux image osc will see the device and can connect to it, if I'm using my custom firmware (5.10 adi linux, built with yocto) osc will see the device just like with the Kuiper image, but when I click connect the window will freeze for a second, the blue LED sw_cc on the CN0540 will illuminate, then osc crashes, and nothing happens after.
    

    libiio on the device is version 0.25.
    

    osc is on version 0.16.
    

    There was a point earlier in development that osc would work with our custom firmware, but I haven't used osc in a while, and I don't know what change would have caused an issue.
    

    Some of the changes include adding support for swupdate, and adding some gpios to the HDL and devicetree.
    

    

    This is the output from iiod when trying to connect:
    

    New client connected from fe80::529a:df3:54df:bd10%end0
New client connected from 192.168.1.154
Client exited
Client exited
New client connected from fe80::529a:df3:54df:bd10%end0

New client connected from 192.168.1.154

New client connected from fe80::529a:df3:54df:bd10%end0
Client exited
New client connected from fe80::529a:df3:54df:bd10%end0
Client exited

    

    

    Is there any configuration for iiod, I missed? Are there any log files I could check?

      Hello,
      

      This was indeed a bug in osc.
      

      We fixed it here : https://github.com/analogdevicesinc/iio-oscilloscope/commit/8ae984733f07ff60b4a01567636d1bef219da41c
      

      Rebuilding osc using the branch above should solve the crash.
      

      Let me know if this fixes your issue.
      

      Thanks.

        Hello  ,
        

        I do not currently have a linux system set up to build osc, are there any build instructions for windows?
        

        Windows is where I have been using osc anyway, and would like to test on the same system where the problem originally occurred.
        

        I mistakenly forgot to mention that in my question.
        

        Thanks,

        Hi, Wyatt.
        

        We provide windows installers that you can download from our github repo, in the actions tab, in the artifact section.
        Here's the installer for that specific commit : https://github.com/analogdevicesinc/iio-oscilloscope/actions/runs/6390209340
         
        Please make sure that you are logged into github, in order to be able to download the installer. 
        Let me know if this fixes your issue.
        

        Thanks.

          Hi Cristina,
          

          I've installed the version of osc you linked, however it doesn't seem to have affected the issue, osc still crashes right after connecting to the device.
          

          Here are two outputs from iio_info, one before trying to connect with osc, and one from after, hopefully helpful when finding what is causing osc to crash.

            Hi Cristina,
            

            I've installed the version of osc you linked, however it doesn't seem to have affected the issue, osc still crashes right after connecting to the device.
            

            Here are two outputs from iio_info, one before trying to connect with osc, and one from after, hopefully helpful when finding what is causing osc to crash.
