MAX98090 crash on Omega2+



  • Good morning to all,
    I need audio on my Omega2+, so I connected a MAX98090 chip to it. The operating system recognize it, but, after enabling i2s with the omega2-ctrl command, when I try to use it (for example with aplay), the entire system crashes and I need to switch off and on.
    I tried different build version (B200, B232, B193,B180...) but the result is the same.

    Please can some one help me?



  • Please post details on the crash. Might be a good idea to have a serial connection to the console so you can see specific info on a kernel panic, etc., etc., etc.

    Thanks William, I didn't think to connect the serial console (the ssh console crashes without any message). I will do as soon as possible.

    Good mornig Bill,
    I reproduced the issue and this is the console trace, after entering aplay message.wav:

  • @Maurizio-Messa Here is grasping at straws, but..... The time or three I've seen a failure to sync I was able to fix the problem by reflashing the device. See https://docs.onion.io/omega2-docs/factory-reset.html. Ought to take just a few minutes.

    Again, grasping at straws. If that doesn't help I'll take a more detailed look at it.

    take care!
