SoftwareSerial.h: No such file or directory :(

Official Hardware Portenta Family Portenta H7
1

Hi guys
im trying to move a sketch from the arduino UNO over to the portenta, i wrote it on the UNO because I hadnt updated the IDE for years and was getting very slow compile times on even blinkwithnodelay for the portenta, but now I need to use the protenta,
i updated to 1.8.19
but when I compile the sketch it gives the following error:
SoftwareSerial.h: No such file or directory
i have gone through the sketch and changed all references to pin 13 to LED_BUILTIN in an attempt to avoid problem as I read that pin 13 is used for serial on the portenta?

Is there anything I can try to fix this without posting the sketch ? I cannot publically share it.

thanks in advance for any help

Some info here;

thanks for your reply, I have looked through that thread before posting, cant really work out whats going on though.

I have resorted to the example code for softwareSerial. It also gives the same error, which at least gives hope that my code will be useful once i sort the issue.

this is the error with verbose enabled:

this is what i have concerning libraries:

#include <SoftwareSerial.h>; //header file of software serial port
SoftwareSerial meSerial(0, 1); //define software serial port name as meSerial and define pins
#include <EEPROM.h>

which generates the follwing message:

SoftwareSerial.h: No such file or directory

however if i swap the eeprom library to the top line like this:

#include <EEPROM.h>
#include <SoftwareSerial.h>; //header file of software serial port
SoftwareSerial meSerial(0, 1); //define software serial port name as meSerial and define pins

then I get the following error instead:

EEPROM.h: No such file or directory

So perhaps the issue is more to do with where the Portenta looks for the libraries?

Or maybe the Portenta has no EEPROM and does not implement SoftwareSerial since it has so many hardwaree serial ports

well, the lack of eeprom isnt something I expected. thats a bummer, i guess i have to find another way to save calibration data on this board now.

as for software serial. im pretty sure others have got it working though.....
