4.2.2 Causes Nicla ME to crash when receiving input over I2C

[kdinev-IEC]

Description

I have the bare-bones configuration with Nicla ME and Portenta H7. Running the "App.ino" example from BHY2 library on Nicla ME and "Temperature.ino" example from BHY2Host library on Portenta H7. Connected as a shield configuration.

When using the latest version of the mbed core (4.2.2), whenever the Nicla receives any data over I2C, mbed crashes with the following msg:

Fix

This error does not appear when using version 4.2.1, and everything works fine.

Source Code

Portenta H7:

#include "Arduino.h"
#include "Arduino_BHY2Host.h"

Sensor temp(SENSOR_ID_TEMP);

void setup()
{
  Serial.begin(115200);
  while(!Serial);

  BHY2Host.begin(false, NICLA_AS_SHIELD);
  temp.begin();
}

void loop()
{
  static auto printTime = millis();
  BHY2Host.update();

  if (millis() - printTime >= 1000) {
    printTime = millis();
    Serial.println(String("Temperature: ") + String(temp.value(), 3));
  }
}

Nicle ME:

#include "Arduino_BHY2.h"

void setup()
{
  BHY2.begin(NICLA_I2C, NICLA_AS_SHIELD);
}

void loop()
{
  // Update and then sleep
  BHY2.update(100);
}
