M5 Stick C : "Guru Meditation Error: Core 0 panic'ed (LoadProhibited)"



  • Using Arduino 1.8.12 , Library: M5StickC 0.2.0

    My M5Sticks run anywhere from 2days to 3 weeks and then crash.
    The crash typically happens right after some WiFi networking call.
    For example:
    crash after: http.begin(g_wClient , g_cHttpCmd);
    or crash after : iRSSI = WiFi.RSSI();

    After the crash, the M5 Stick C does not automatically reboot , which I believe it should

    Attached is the debug output:
