How to copy the firmware from one chip to another using the Silicon laboratories IDE

In the silabs IDE Use tools / upload memory to file, and save it as hex

convert it to binary (ex. the code below)
convert from binary to intel-hex
 sudo apt-get install srecord
 srec_cat file.bin -Binary -Output file.hex -Intel

use silabs ide Debug/dowload object file to write the file



====FROM HEX TO BINARY====

#include <iostream>
#include <fstream>

using namespace std;

int main(int argc,char** argv){
  if (argc<3){
    cout<<"Usage "<<argv[0]<<" infile.hex.txt outfile.bin"<<endl;
    return 0;
  }
  fstream in(argv[1], ios::in);
  fstream out(argv[2], ios::out | ios::binary);
  int h;
  while(in){
    in>>std::hex>>h;
    unsigned char c=h;
    if (in){
      out.write((char*)(&c),1);
    }
  }
  out.close();
}
