undefined reference to `BlockDevice::get_default_instance()' and other problems with flash examples

[mirkopac]

Hi, I'm trying the various examples for the flash features of the Uno R4 but a recursive compilation error is as follows:

undefined reference to `BlockDevice::get_default_instance()'

The problem is caused by the lack of the right tag for the architecture in the BlockDevice file.cpp :

ArduinoCore-renesas/libraries/BlockDevices/BlockDevice.cpp

Line 20 in 149f78b

#ifdef ARDUINO_PORTENTA_C33

by correcting and putting adding the right platform macro for example ARDUINO_UNOR4_MINIMA, the problem moves to compiling and defining parts of the QSPIFlashBlockDevice library.

Is this a known problem? I can't use the flash features of the board.

I use the last core 1.0.1 for Arduino Uno R4.
