各位大哥，现在我想测试一下大端和小端的问题，可是用s3c44b0去测试的时候，编译器是ADS1.2，跑下面一段程序，发现把language setting 中的byte order改为big endian后，程序下载后就跑不了；改为little endian后，程序就可以跑，请问这是为什么啊？

    lAddress=(unsigned short)(address32&0xffff);  //should be 0x5678
    hAddress=(unsigned short)(address32>>16);   //should be 0x1234
    printf("the sizeof long is %x,the sizeof short is %x ",sizeof(long),sizeof(short));
    printf("the Address is %x ",address32);
    printf("the lAddress is %x ",lAddress);
    printf("the hAddress is %x ",hAddress);
    printf("finished");

The S3C44B0X memory controller provides the necessary memory control signals for external memory access.
S3C44B0X has the following features;
— Little/Big endian(selectable by an external pin)
