Fails to compile Strings declared empty on Atmega328PB about minicore HOT 3 OPEN

Hi!

Can you post the compiler error you're getting?

from minicore.

Hey! Thanks for getting into so quick

The fact is I do not receive compiler errors , but same code works differently when I compile with Minicore or Native Arduino Ide.

With Arduino Ide the string works as expected (forcing avrdude to program the 328PB as 328P), but not when I compile with Minicore, I dont receive compile errors, but the String does not work as expected, does not capture serial data.

This is some (reduced) code you can reproduce the failure, data is received thought serial port (native serial for 328P)(Not used serial 1 option for 328PB).

String inputString = ""; // declared variable

while (Serial.available() > 0) { // Under loop function

char inChar = (char)Serial.read();
inputString += inChar;
delay(20);
}

from minicore.

Just an update into the problems found into the Atmega328PB, definitely is related to the managements of Strings, none of the strings apparently works, I did a fresh installation of minicore and problem remains the same.

The problem with the Strings disappear when I compile my 328PB as 328P with the Arduino Ide standard compiler ( However other small problems arises at other areas due to different registers identifiers).
