Arduino Portenta H7 Lite with mcp2515

Official Hardware Portenta Family Portenta H7

Hi,

I'm using the autowp-mcp2515 and Arduino_PortentaBreakout library for a CAN BUS interface using the Arduino Portenta H7 Lite.

#include <SPI.h>
#include <mcp2515.h>
#include <Arduino_PortentaBreakout.h>

struct can_frame canMsg;
MCP2515 mcp2515(SPI1_CS);


void setup() {
  Serial.begin(115200);
  
  mcp2515.reset();
  mcp2515.setBitrate(CAN_125KBPS);
  mcp2515.setNormalMode();
  
  Serial.println("------- CAN Read ----------");
  Serial.println("ID  DLC   DATA");
}

void loop() {
  if (mcp2515.readMessage(&canMsg) == MCP2515::ERROR_OK) {
    Serial.print(canMsg.can_id, HEX); // print ID
    Serial.print(" "); 
    Serial.print(canMsg.can_dlc, HEX); // print DLC
    Serial.print(" ");
    
    for (int i = 0; i<canMsg.can_dlc; i++)  {  // print the data
      Serial.print(canMsg.data[i],HEX);
      Serial.print(" ");
    }

    Serial.println();      
  }
}

When I upload this sketch, the Arduino Portenta H7 Lite immediatly goes into SOS mode (4X blink red LED short, 4X blink red LED long) when going through line 5&6 of the sketch (creating the mcp2515 object).

What could be the problem here?
