PlatformIO and FreeRTOS

Illerian

A little help would go a long way!

I am trying to use FreeRTOS with PlatformIO on my M5Stack Core 2

I can get it to work on cpu core 1 but not on cpu core 0. Any suggestions?

I am suspicious that it has to do with SPI communication with the LCD screen. I am hoping I am doing something wrong. It is easier to fix my faults than those of TFT_eSPI or M5Display.

Thanks in advance!

Code snippet

xTaskCreatePinnedToCore(loop,"task1",8192,NULL,1,taskHandle,1); //Works

xTaskCreatePinnedToCore(loop,"task2",8192,NULL,1,taskHandle,0); // Sets CPU in panic and reboots

void loop(void *parameters) {
    while(1) {
        M5.Lcd.println("Somthing to think about!");
        Serial.println("Something to ponder?");
        delay(1000);
}
