Hi Andy, I don't know enough about ESP32 to know whether this will be an issue on this board, but using one of the Lyra-T boards, or similar, I was not able to get much Faust code running on it before I started hitting watchdog errors etc. I outlined all of my tests and results in the ESP32 section of the Faust Slack channel about a year ago.
