Running two tasks on M5Stack

[malbrook]

Hi
I am working on a project that uses M5ez as the screen handler with the main screen giving access to the M5ez menus through a button but with the initial screen containing live data updated from a second task running on the other core in the M5. When I moved the code that displays new data on the screen from the main task which is also handling the web server to the second task I ran into an exception problem with the exception pointing to the call to clear the canvas.
0x400e1191: ezCanvas::clear() at Arduino Sketchbook\libraries\M5ez\src/M5ez.cpp line 2118
0x400d506f: appUpdateTemperature() at menu_functions.cpp line 53 (discriminator 2)
0x400dc17c: Task2Main(void*) at task2.cpp line 183
0x400897e1: vPortTaskWrapper at esp-idf-public/components/freertos/port.c line 355

Moving the calling code back to the main task removes the problem, any thoughts on why it only works in the main task and not in a task running on the second core. The code to start the second task is included below.

// Start task for second core
xTaskCreatePinnedToCore(
    Task2Main,      /* Task function. */
    "TaskCore2",    /* name of task. */
    3072,           /* Stack size of task */
    NULL,           /* parameter of the task */
    1,              /* priority of the task */
    &TaskCore2,     /* Task handle to keep track of created task */
    0               /* Core */
);
