Describe the problem
Sketches involving the Serial.begin() will not compile, without adding #include "SerialRPC.h" at beginning of sketch. It will compile when #include "SerialRPC.h is added to the beginning of the sketch
To reproduce
From root of repository run
cd .\examples\01.Basics\AnalogReadSerial\
arduino-cli compile -b arduino:mbed_portenta:portenta_x8 -v
Output

Expected behavior
In the Out of Box (OoB) experience for the Portenta X8, it is possible to compile and run Arduino example sketches (included in the IDE) using Serial functionality without any additional modification.
The Arduino website mentions the ability to run Arduino code on the auxiliary core of the Portenta X8 in many places, including:
- Portenta Mid Carrier Docs page
- Portenta X8 Docs page
- The Arduino Pro page for the X8 mentions that the Portenta X8 combines
Arduino and Linux ecosystems
The examples version
Additional context
Repeatable with Arduino IDE 2.3.2
Issue checklist
- I searched for previous reports in the issue tracker

Hi @aliphys. The examples hosted in this repository are intended to serve as an introduction to the Arduino programming language. Although we could add support to the examples for the Portenta X8, the added added code would make the examples significantly less approachable to beginners.
Since the Portenta X8 is a "PRO" product, which is only for use by advanced users, it is not worth making harmful changes to the examples hosted in this repository in order to support that board.
