GigaR1 + GigaDisplay on M4 Core

Official Hardware Mega GIGA R1 WiFi
1

Good morning at all ,
I' have a question , GigaDisplay it's supported by M4 Core?
because I dividing my application on 2 skecth M4 Sketch used for GIGA Dispaly and M7 used for the other.
when M4 booting , the code stopping when the Initialized Display. why?

#include "Arduino.h"
#include <RPC.h>
#include "Arduino_H7_Video.h"
#include "lvgl.h"
#include "Arduino_GigaDisplayTouch.h"
//#include <SPI.h>
//#include <DigitalOut.h>
//Arduino Giga R1 Access Point UDP

//librerie Gestione USB

  // put your setup code here, to run once:
  Serial.begin(115200);
  RPC.begin(); // boot M4
  RPC.println("M4 Avviato");
  //Display.begin();
  //TouchDetector.begin();
  //setupDisplay();
 //InizializzaVariabili();

}

  RPC.println("SetupDisplayIN");

Hello,

I have the same problem aswell but unfortunately not solution.

Hi!
With the newest update of the giga board library it boots the display from the M4, but the graphics look very bad, like interleaved layers. setting the display size to a smaller number like:

Arduino_H7_Video Display(799, 479, GigaDisplayShield);

helps the graphics, but there are still bugs.

Hope a quick solution for the issue will be available soon

HI!!
thanks for solution .
I will try
