Simple webserver working on ESP32, not on Core2

  • I have a simple code that draw data from a csv file on a webpage.

    The server used is ESPasyncwebserver.

    Loading this code on ESP32 alone is working fine, but when loading on M5core2, it crash every time I try to load the webpage...

    Any idea where this problem comes from?

    Here is the watchdog error :

    ERROR: Too many messages queued
    ERROR: Too many messages queued

  • Hello @Leo05

    does the simple server example also crash? If not, the issue probably is related to the csv file reading?


  • Hi @felmue

    No, the example server works fine. You are right, it was probably an issue with csv reading.

    Thank you
