[ts-7000] Endianess Problem

["Adriano Naspolini" <>]

Hi people,

I'm having some problems with arm endianess of floating types.

For example, the "double" value 10.0:
my PC writes it to a file:
0x00.00.00.00.00.00.24.40
while the TS-arm writes:
0x00.00.24.40.00.00.00.00

So, when arm reads a binary file written by a PC it interprets a wrong value, 
and vice-versa. This causes a lot of problems when using third part libraries 
and standards.

If anyone wants to check, I attached a program to illustrate it. Running it on 
PC and on ARM will show the numbers above.

Regards

Adriano

#include <iostream>
#include <fstream>
using namespace std;

int main() {
        double d = 10.0;

        ofstream of("teste.bin");
        of.write((const char *)&d, sizeof(double));
        of.close();

        ifstream ifs("teste.bin");
        for (unsigned int j = 0; j < sizeof(double); j++)
        {
                char c;
                ifs.read(&c, 1);
                cout << "in the file, i["<< j << "] = "<< std::hex << (int)c << 
endl;
        }
        ifs.close();
        return EXIT_SUCCESS;
}
