Other Steps to Reproduce

connect to usb, send SERIAL, crash

I have checked existing issues, online documentation and the Troubleshooting Guide

lbernstone commented 1 month ago

TL;DR. This looks a lot like a problem with your code. Make a minimal example. This is a pointer memory violation, so those strcpy are almost certainly the problem.

Red-Owl commented 1 month ago

i have disabled a final code strcpy,
this code create a crash: 

String gatto_get_serial(){
  String str = NVS.getString("serial");
  return str;
}

if(com=="ass"){
        String ass = gatto_get_serial();  // call a function
        USBCOM.write(ass.c_str());  
      }

-------------this code not crash:-----------------------------


if(com=="ass"){
        String ass = NVS.getString("serial");   // this non crash
        USBCOM.write(ass.c_str());  
}

Pass pointers, not Strings. You are making lots of extra copies of the objects, and then attaching a local stack variable to your heap function result. In this case, keeping things as char (or even const char) all the way through will be much more efficient.
