在文件common/cmd_load.c文件中

U_BOOT_CMD( loadx, 3, 0, do_load_serial_bin, "load binary file over serial line (xmodem mode)", "[ off ] [ baud ]\n" " - load binary file over serial line" " with offset 'off' and baudrate 'baud'" );
在do_load_serial_bin函数中增加对loadx命令的处理

else if(strcmp(argv[0],"loadx")==0) { printf ("## Ready for binary (xmodem) download " "to 0x%08lX at %d bps...\n", offset, load_baudrate); addr = load_serial_xmodem (offset); }
