Hello friends,
I have got a not in sync problem , while uploading the program code using arduino pro mini .so I have flashed the boot loader code of uno in arduino pro mini via Arduino uno through SPI lines , thinking that boot loader of pro mini is crashed .. boot loader code is flashed successfully in pro mini and even the program code is uploaded in arduino pro mini via Uno. But if I upload the program code separately using USB cable in pro mini , I will get the same error as not in Sync .. Can any one explain me what is the problem ??
