I am using portenta H7 with vision shield - LoRa

Trying to run this two codes didn't work for me:

• https://github.com/arduino/ArduinoCore-mbed/blob/master/libraries/STM32H747_System/examples/STM32H747_updateBootloader/STM32H747_updateBootloader.ino
• https://github.com/arduino/ArduinoCore-mbed/blob/master/libraries/STM32H747_System/examples/STM32H747_getBootloaderInfo/STM32H747_getBootloaderInfo.ino

After successfully uploading the file, I never saw the output on terminal.

When uploading different sketches, they work, just this one doesn't (I even tried to leave terminal opened for around 1 minute, just in case it will take long time to pop up)

Running the following code through different sketch:

  uint8_t* bootloader_data = (uint8_t*)(0x8000000 + 0x1F000);  uint8_t currentBootloaderVersion = bootloader_data[1];  Serial.println("Bootloader version: " + String(currentBootloaderVersion));

Resulted in me learning I am running bootloader v 21.

Now, I am unsure if this is my problem, or it's an issue with the new core update.
