Hello everyone,


When I use the example program for I2C located in <install_dir>\Freescale\Freescale_MQX_4_1\mqx\examples\i2c,I found the program stop at "result = fwrite (mem, 1, 1, fd);"

The E2PROM type is 24C02.


   mem[0] = (uint8_t)addr;
   printf ("  Write to address 0x%02x ... ", mem[0]);
      result = fwrite (mem, 1, 1, fd);
      printf("\r\n Hello World \r\n");
   } while (result < 1)


Need help,thks!
