i have this error

Low memory available, stability problems may occur. Does it affect the processor? atmega128

[lshw]

The stack length may be insufficient.

This is problem with your code not core. You must use micro with more ram or optimise yout code. Anyway we need more informations about your hw setup and your code

Does this affect the operation of the processor?

The code is very private, it cannot be published and is too large

[tomaskovacik]

Then you must simply test it

[MCUdude]

Optimize your code to use less RAM, or choose a larger, pin compatible microcontroller with more RAM such as the Atmega1281 or ATmega2561.

[fadi0albaghdadi]

Does that mean I can replace the atmega128 processor with atmega1281

[MCUdude]

Yes, as long as your hardware setup doesn't depend on anything unique to the ATmega128.

[lshw]

use F(string) to put string into ROM.

Serial.println("hello"); // use 5 byte ram, Serial.println(F("hello")); // use 0 byte ram

F(string) can save a lot of ram.
