M5Stack Core 2 guru meditation during sprite create

PlatformIO IDE
,
1

Hi,

I’m using a M5Stack Core 2 board and the Arduino framework and need to use sprites for display but my code (simple demo code from M5Stack) always crashes with Guru Meditation Error. The crash occurs in the line:

 img.createSprite(320, 240);    //Create a 320x240 canvas

I don’t understand what I’m doing wrong?

platformio.ini

[env:m5stack-core2]
platform = espressif32
board = m5stack-core2
framework = arduino
lib_deps = m5stack/M5Core2
monitor_speed = 115200

main.cpp

#include <M5Core2.h>
#include <Arduino.h>

TFT_eSprite img = TFT_eSprite(&M5.Lcd);

void setup() {
    // Init Serial
  Serial.begin(115200);
  Serial.println("Starting...");
  
  // Sprite Test
  M5.begin();  //Initialize M5Core2
  img.createSprite(320, 240);    //Create a 320x240 canvas
  img.fillSprite(RED);    //Fill the canvas with red
  img.fillCircle(100,100,20,GREEN);
  img.pushSprite(0, 0, GREEN);    //Push the canvas to Screen(0,0) and set white as the penetration color
}

void loop() {
  // put your main code here, to run repeatedly:
}

Please activate the backtrace decoder and debug mode so that we know where it crashes.

monitor_filters = esp32_exception_decoder
build_type = debug

Reupload + monitor again

Here is the output with activated backtrace decoder & debug mode:

Hm, calling ps_calloc crashed.

Are you using the new Arduino-ESP32 2.0.1 core with PlatformIO? Did a CLI → pio platform update espressif32?

5

Uh, I’m very sorry!
After updating the Espressif Platform from 3.5.0 to 4.2.0 everything works fine!

Thanks @maxgerhardt
