I just followed the tutorial in Get Started With Round Display
From Step1 to Step5
And after I uploaded the “HardwareTest.ino” to my board
The serial Monitor showed this error, and the display didn’t show anything.
Error Message:
XIAO round screen - LVGL_Arduino
Guru Meditation Error: Core 1 panic'ed (StoreProhibited). Exception was unhandled.

Here’s the code:
#include <lvgl.h>

void setup()
{
Serial.begin( 115200 ); //prepare for possible serial debug
Serial.println( "XIAO round screen - LVGL_Arduino" );
lv_init();
lv_xiao_disp_init();
lv_xiao_touch_init();
lv_hardware_test();
}
void loop()
{

delay( 5 );
}
Thank you!
